Mojave River flows through Barstow for first time since 2011

BARSTOW — Recent rains allowed surface water in the Mojave River to flow through the city for the first time in eight years, signaling good news for recharge in regional aquifers, according to Mojave Water Agency officials.

MWA Senior Hydrogeologist/Engineer Tony Winkel told the Daily Press inflow to the Mojave River at its headwaters on Thursday peaked at approximately 15,000 cubic feet per second, according to provisional estimates.

That inflow surged through the inlet within the Mojave River Dam, sometimes called the Forks Dam, where the Deep Creek and West Fork tributaries converge.

Winkel said previous storms in recent weeks allowed the river to soak up water “like a big dry sponge.” Because the river can only absorb water so quickly, though, water from last week’s storm subsequently “skirted” along through Barstow, petering out just beyond Minneola Road in Yermo late last week.

“Minneola Road is kind of the upper end of the Baja subarea, but it was kind of a trickle,” Winkel said. “So right at the headwaters, it’s raging. You get down to the tail end of it, it’s just trickling because that much water has soaked in, which is a good thing because that’s water supply.”

Amid the worst drought in California history several years ago, the High Desert finally received some wet weather in 2017. But that water didn’t reach Barstow, which makes last week’s storm significant because it was the city’s “first influx of water since 2011,” Winkel said.

To understand just how much water flowed into the Mojave River on Thursday, MWA Water Conservation and Forecast Manager Nick Schneider said to imagine 15,000 basketballs bouncing through the inlet — in one second.

The analogy isn’t precise, according to Schneider and Winkel because a basketball isn’t exactly one cubic foot. Schneider, however, said the “industry conversion idea” is fair for visualization purposes.

“For the layman, if you think of a basketball, that’s a good way to process it,” Winkel said. “For an engineer, it drove me nuts.”

While 15,000 CFS is impressive and welcome, Winkel said last week’s storm, historically, pales in comparison to older weather events that brought significant inflow at the Mojave River’s headwaters.

On March 4, 1978, inflow peaked above 35,000 CFS, according to data Winkel provided. Some 40 years earlier, during what’s been called the “flood of the century” that ravaged the High Desert in March 1938, inflow peaked at nearly 75,000 CFS.

The data, which included estimates as far back as December 1859, showed at least 16 peak events with a magnitude above 25,000 CFS, including a Jan. 22, 1862, incident during which inflow is estimated at more than 100,000 CFS.

That peak came during the Great Flood of 1862, which started with a series of storms in December 1861 and is considered the largest flood in California’s history. It’s unknown how much damage occurred locally, but Sacramento was underwater for months. Schneider said newly elected Gov. Leland Stanford had to travel by rowboat to and from his inauguration in January.

Winkel said last week’s storm was nowhere near even the peaks seen in the wet winters of 2010 and 2011, which were also below 25,000 CFS. That said, it’s important in its own right because it equals recharge for the High Desert’s water supply, he said.

Consequential weather events occur, on average, every six to eight years, but that cycle isn’t consistent and the peaks are “very variable”, according to Winkel. Still, the High Desert, insofar as water supply is concerned, relies on peak events like the one experienced last week, he said.

“So how significant is it that the water made it to Barstow?” Winkel said. “Very. Because that’s the natural supply that we depend on.”

Specific recharge data for last week’s storm is not yet available because “we’re still in the storm swell,” according to Winkel, who said he’s hoping for more rain this year.

“Aside from the excitement factor of a river that’s actually flowing, which is very exciting because it usually doesn’t, I want to see more for water supply purposes.”

LADWP scrambling to prepare dusty Owens Valley for possible floods

Lone Pine, Calif. -- As snow continued to fall on the eastern Sierra Nevada on Monday, platoons of earth movers, cranes and utility trucks fanned out across the Owens Valley, scrambling to empty reservoirs and clean out a lattice-work of ditches and pipelines in a frantic effort to protect the key source of Los Angeles’ water.

With snowpack levels at 241% of normal, Los Angeles Mayor Eric Garcetti a week ago issued an emergency declaration allowing the Department of Water and Power to take immediate steps to shore up the aqueduct and its $1-billion dust-control project on dry Owens Lake, which L.A. drained to slake its thirst in the last century.

DWP activities have always elicited concern in the Owens Valley, given the history of a water war that began when Los Angeles agents posed as ranchers and farmers to buy land and water rights in the area. Their goal was to build the aqueduct system to meet the needs of the growing metropolis 200 miles to the south.

The stealth used to obtain the region’s land and water rights became grist for books and movies that portrayed the dark underbelly of Los Angeles’ formative years, and inspired deep-seated suspicions about the city’s motives that linger to this day.

Officials insist that the current emergency poses a real threat not just to urban Los Angeles’ residents, but to the ranchers, farmers, outdoor enthusiasts and small-business owners living in the sage-scented high desert gap between the fang-like peaks, some taller than 14,000 feet, of the Sierra Nevada to west and the White and Inyo ranges to the east.

“Conditions of extreme peril” threaten residents and ecosystems, Garcetti said. The 1 million acre-feet of water expected to flow through the century-old aqueduct system this spring and summer could possibly overflow the web of concrete channels, spilling into fields, homes and businesses.

The danger of destructive flooding and the utility’s responses to it are raising tensions between Los Angeles and the Owens Valley towns along a 110-mile stretch of U.S. 395 in a rural region defined by water wars since the early 1900s.

The crews swarming the valley are focused on protecting DWP infrastructure and U.S. 395, the principle route between Southern California and eastern resort areas, leaving some townsfolk fretting they are being overlooked.

The emergency is already taking toll on the tourism industry in a stunning landscape of snow-capped peaks, cascading streams, dormant volcanoes, small towns and sage plains dotted with irrigated pastures — most of them leased from the DWP.

The Bishop Chamber of Commerce & Visitors Bureau, for example, was forced to cancel the 50th annual Blake Jones Trout Derby scheduled for March 11 after the DWP rescinded its permission to hold the event because of dangerously high waters spilling over the banks of the Owens River, just north of town.

“Losing the derby was a $300,000 hit to the local economy,” said Tawni Thompson, director of the chamber. “We’ll never know how many vacationers decided not to come through Bishop because they were scared of dying in a flood.”

“I’m going to declare a state of emergency,” she added, “if our tourism industry goes down the toilet.”

Bernadette Johnson, superintendent of the Manzanar National Historic Site on U.S. 395, has been getting nowhere with requests for additional flood control measures along streams on DWP land just outside the boundaries of the location that was a Japanese American internment camp during World War II.

“We were hit by destructive flooding earlier this year, and in 2013 and 2014,” Johnson said. “But the DWP is saying that when all hell breaks loose they won’t have enough resources and manpower to help us. We have to wonder about their priorities.”

In long legal battles spanning decades, the DWP was eventually forced to give up significant amounts of water to steady water levels in Mono Lake, re-water parts of dry Owens Lake to help prevent dust storms and restore a 62-mile stretch of the Lower Owens River.

Many residents suspect that the DWP plans to use emergency declarations to bypass rules and regulations that have prevented it in the past from constructing paved roads, for example, on Owens Lake, which is owned by the State Lands Commission.

Richard Harasick, head of the DWP’s water system, dismissed that notion: “The department is not using this emergency declaration to take some sort of advantage or build special projects that would otherwise have to go through the normal regulatory process.”

“It is as much to help us manage the anticipated floodwaters as to aid in public safety,” he said. “It allows us to get goods, services and contracts faster, from heavy equipment to riprap needed to shore up banks and channels.”

This week, Inyo, Kern and Mono counties were expected to issue their own emergency declarations, making them eligible for state and federal assistance in the event of flooding.

“My proclamation will ask for critical resources,” Inyo County Administrator Kevin Carunchio said. “In the meantime, I want every DWP facility, ditch, diversion bypass, canal and conveyance structure available and operating as soon as possible.”

The region has a history of destructive floodwaters rushing off the High Sierra.

In August 1989, for example, cloudbursts driven by 60-mph winds gouged out the underpinnings of the aqueduct near Cartago and closed a 63-mile stretch of U.S. 395.

Jon Klusmire, administrator of the Eastern California Museum in Independence, isn’t taking any chances with the little institution located along a usually docile creek.

“I’ve devised a survival strategy for a worst-case scenario,” he said. “I’m going to jam some boards in a nearby DWP diversion gate, then dig a ditch to divert the water away from the museum and into the streets.”

The big question for Kathy Jefferson Bancroft, tribal historic preservation officer for the Lone Pine Paiute-Shoshone Reservation, is this: “How could it be that Los Angeles never developed a plan B in a place where massive snowpack and destructive flooding go with the terrain?”

Standing on a berm overlooking on the plots of vegetation, gravel and shallow flooding the DWP has constructed across 50 square miles of dry lake bed over the past 20 years, Bancroft said, “They’ve reduced dust pollution here by 96% with these projects, and they’re all going to be underwater soon.

“Honestly, I’m looking forward to seeing this lake filled up again, like it is supposed to be,” she said.

That vista will be short-lived. The runoff is expected to evaporate within 12 to 18 months, leaving behind an already existing repair job for dust abatement and system improvements expected to cost up to $500 million, officials said.

The rebuilding effort will be done in cooperation with state and federal regulatory agencies, local authorities and stakeholders, the State Lands Commission, which owns the lake bed, and the Great Basin Unified Air Pollution Control District, which is responsible for protecting the health of Owens Valley residents.

“When we’re done, it’ll be something different than what exists today,” Harasick said. “That’s because we plan to make it more flood-resilient.”

Feds to flood Grand Canyon to distribute sediment

PAGE — Campsites along the Colorado River through the Grand Canyon will be in shorter supply as federal officials flood the waterway.

The high-flow release from Glen Canyon Dam in northern Arizona is scheduled to start Monday and end Friday. It's the third under an innovative science-based experimental plan approved in May 2012.

Tons of sediment from river channels will be re-deposited along downstream reaches as sandbars and beaches along the river. Grand Canyon officials say most campsites will be smaller and some low-lying sites might not be usable.

Most of the sediment once deposited throughout the Grand Canyon now is trapped behind the dam near the Arizona-Utah border. The intent of the flooding is to mimic pre-dam conditions.

The Arizona Game and Fish Department says the release should enhance trout fishing.

Feds begin high-flow releases from Glen Canyon

Experiments will occur yearly in hope of restoring Grand Canyon’s ecological vitality.

Page, Ariz. -- Federal water mangers and scientists Monday began ratcheting up releases from Glen Canyon Dam as part of a five-day experiment to push sediments down the Colorado River in hopes of restoring sandbars that play a vital ecological role in the river channel.

This week’s high-flow releases, designed to mimic the pre-dam natural flooding, mark "an historic milestone" for river management, according to Interior Secretary Ken Salazar.

"It was an honor to open the door to a new era for Glen Canyon Dam operations and the ecology of Glen Canyon National Recreation Area and Grand Canyon National Park — a new era in which we realize that the goals of water storage, delivery and hydropower production are compatible with improving and protecting the resources of the Colorado River," Salazar said after he personally triggered releases at noon through the dam’s outlet tubes that bypass the turbines.

The federal Bureau of Reclamation began experimenting with high flows in 1996; this week’s event is only the fourth experiment. The others occurred in 2004 and 2008.

But the frequency of future releases will increase — to the delight of conservationists — under protocols Salazar announced in May.

"We have been pitching Interior for years to do these as often as the sediment in the system warrants. They rejuvenate all the sediment-related resources," said Nikolai Lash, a program manager with the Grand Canyon Trust. Under the new protocols, high-flow releases are expected to occur as often as once or twice a year, depending on the accumulation of downstream sediments.

Scientists led by Utah State University geomorphologist Jack Schmidt will closely monitor the effects of these high flows for the next several years. Their findings will help guide a long-standing "adaptive management" strategy for the Southwest’s signature river, which has carved one of the world’s most scenic landscapes. Damming the river produced a windfall of electrical power, but it also wrecked the river’s ecology and pushed warm-water fish species toward extinction.

"By early 1990s, the scientific community recognized it would be impossible to restore native ecosystems without controlled floods because they reintroduce disturbance into the ecosystem," said Schmidt, who now works for the U.S. Geological Survey. A professor of watershed sciences, Schmidt remains on unpaid leave from his USU appointment while he leads the Grand Canyon Monitoring and Research Center in Flagstaff, Ariz.

By disturbance, Schmidt was referring to the massive floods that once roared through Glen and Grand canyons, with flows in excess of 50,000 cfs (cubic feet per second) occurring most years and in excess of 125,000 cfs every eight years on average. Before the 1966 completion of the 710-foot-high Glen Canyon Dam, which forms Lake Powell, the Colorado pushed millions of tons of eroded sediments downstream, creating a rich network of sandbars that supported fish and riparian communities along Grand Canyon’s floor, not to mention great camping spots for river runners.

The dam impounds 95 percent of the natural sediment flow, then releases water at a steady rate of 7,000 to 9,000 cfs, which prevents sediments building up at the mouths of tributaries from being pushed downstream, according Schmidt.

Storms flood parts of Vegas, Navajo land, Calif. desert communities, Utah town

Residents in four Southwest states were drying out Wednesday after thunderstorms flooded Las Vegas streets, stranded Navajo families in northern Arizona, left two mobile home communities in Southern California deep in water and caused a dike to fail in a Utah town.

In the Las Vegas area, the Tuesday storms delayed flights, snarled traffic and prompted helicopter rescues of stranded motorists. A golf course worker was reported missing and a search for the man resumed Wednesday, NBC affiliate KSNV-TV reported.

Television news video showed school buses inching along roads after school east of downtown Las Vegas, and muddy water up to the lower sills of windows of stucco homes in other neighborhoods.

In southeast Las Vegas, authorities urged the residents of about 45 homes damaged by flooding to leave in case electrical fires are sparked.

Dozens of cars were swamped by water up to their headlights in a parking lot outside the Thomas & Mack sports arena at the University of Nevada, Las Vegas.

Firefighters responded to more than 20 calls about people in stalled cars .

A Las Vegas police helicopter was dispatched during the height of the storm to pluck several people from swamped vehicles on roadways.

More than 1.75 inches of rain were reported in downtown Las Vegas. The rainfall amounts put the region on pace to exceed the 4.5 inches of rain it normally gets in a year.

Tuesday was also the wettest September day on record in Las Vegas, weather.com meteorologist Nick Wiltgen reported.

Calif. mobile home parks hit hard

In California's Coachella Valley, a thunderstorm on Tuesday dropped more than the average annual rainfall there in one night alone, settling for six to eight hours over Mecca and Thermal, desert towns 150 miles southeast of Los Angeles.

In Thermal, the downpour flooded the Desert Mobile Home Park better known as Duroville, a community of mostly migrant workers with about 1,500 people, including 900 children, that has long been the subject of legal fights as Riverside County officials attempt to relocate residents.

More than a foot of water stood in the southern end of the park, knocking out power to about 800 people for much of the day.

"None of us had ever been through anything like this," said Tom Flynn, the court-appointed receiver for Duroville. "That much water in a dilapidated mobile home park was something to see."

The lack of power knocked out electric motors on both of the park's wells, leaving no fresh water until one was revived and county workers brought several tons of bottled water.

The park has no paved streets or drainage, and health officials were concerned about overflow from two ponds that serve as the community's sewers.

Between 60 and 80 people had evacuated from the park and were spending the night at a high school. "The poorest of the poor were hit the hardest," Flynn said.

St. Anthony's Mobile Home Park in Mecca also was affected, but fared better than Duroville. Video clips showed residents wading through knee-high water and cars creeping through flooded residential streets.

The storm dropped 5.51 inches of rain near Mecca and 3.23 inches of rain near Thermal, meteorologist Mark Moede said. The average annual rainfall in arid Thermal is just shy of 3 inches, he said.

"That's an amazing amount of rain," Moede said. "It's unusual anywhere to get a storm that sits stationary for five to eight hours."

Arizona and Utah flooding

On the Navajo Nation reservation in northeastern Arizona, many of Tuba City's roads were underwater and residents stuck in their homes. State Route 264, one of two main arteries in and out of town, was closed after a bridge washed out about a mile outside of the community, Tuba City Chapter Manager Benjamin Davis said.

Flooding was reported in some homes but no residents were displaced, Davis said.

Meanwhile, a dike that broke during heavy morning rain flooded nearly four square blocks in the southern Utah city of Santa Clara. More than 30 homes and business were evacuated after the break.

City Manager Edward Dickie said the dike along a retention pond sent a deluge of water into downtown.

"It didn't just breach. It broke. It's gone," he said, adding that the flooding quickly receded as water drained into rivers and creeks.

Such a wide area across the Southwest was hit, Wiltgen told NBCNews.com, because moist, unstable air interacted with a disturbance in the upper atmosphere.

"The disturbance helped to trigger the scattered thunderstorms that popped up across a broad swath of the Southwest," he said, "and these storms translated that very moist air into flooding downpours."

Finding a fix for dying Salton Sea

After years of inaction by state, lawmaker wants to put regional group at helm

NORTH SHORE — As state lawmakers held their first summit in more than four years on the looming death of the Salton Sea, Sonia Herbert gazed out the window at the North Shore Beach & Yacht Club marina, where squawking seabirds swooped across the glassy sea surface, fishing for tilapia.

Like most of the 60 people who attended Monday's hearing, Herbert, who has lived in Bombay Beach since the 1970s, fears the worst: that time is running out on efforts to repair the sea and sustain its wildlife, and that overwhelming public health and economic crises will follow.

“All we've seen is studies, studies, studies and nothing has been done,” a visibly frustrated Herbert told Assemblyman V. Manuel Pérez and two Assembly budget committee members. “What's going to happen if we don't do something?”

The state remains broke, and its preferred $9 billion sea restoration plan has languished since 2007.

Sticker shock over the restoration cost has led to political paralysis, but Pérez, a Coachella Democrat whose district includes the sea, has called its restoration his top priority for the rest of his legislative tenure.

At the hearing, which Pérez's office organized, he listened to county supervisors, residents and environmental advocates call for the state to relinquish control and to let locals settle on the best plan to restore the sea and the best way to pay for it.

“The sea needs help and it needs it now. The answer isn't big brother riding to the rescue, because he's not coming. There is no rescue,” Imperial County Supervisor Gary Wyatt told Pérez and two other Assembly members, Republican Brian Jones of Santee and Democrat Richard Gordon of Menlo Park.

“We need to drive this train,” said Wyatt, quoting longtime Riverside County Supervisor Roy Wilson, who died in 2009.

Wyatt and others pushed public-private partnerships on new geothermal and solar energy projects at the sea as a realistic way to tap dollars for Salton Sea restoration.

Wyatt proposed taking a 7,000-acre former military test site at the sea's south shore, now controlled by the federal Bureau of Land Management, and converting it into a renewable energy depot that he said could provide 700 megawatts of power and produce at least $40 million a year in restoration funds.

Unlike redevelopment funds, that money would be exempt from state seizure, Wyatt said after the meeting.

“The interest is here, not there,” Riverside County Supervisor John Benoit said, referring to Sacramento. “What we need is the authority. If we fix this sea… the economic advantages to this area (are) nearly unlimited.”

Pérez said he hoped the hearing would help drum up support in the Legislature for his AB 939 bill, a proposal to switch the authority from the state's Salton Sea Restoration Council — a body that has never met — and place it in the hands of the local Salton Sea Authority, a joint-powers authority of the local counties and local water districts, along with some state presence.

“I'm optimistic that we can find a way if we work together and there's a political will from all levels of government including grassroots,” Pérez said. “Part of the reason why we have not been able to move forward is we're all moving in so many different directions. We need to find consensus to what the issues of the Salton Sea are.”

As runoff from irrigation and other water transfers evaporate, the Salton Sea's salinity has risen while its mass has shrunk. By the end of this decade, its retreat will be even more dramatic.

Created by flooding in 1905 and without a new source of water to replenish it, California's largest lake will grow uninhabitable to fish and the thousands of migratory birds that feed on them.

The exposed lakebed and the dust it generates could be disastrous in an area that already has one of the nation's highest rates for youth asthma, officials say. It also would damage agriculture and tourism.

State budget analysts at the hearing Monday reported that tens of millions of dollars in state bond funds from Propositions 50 and 84 have been spent on proposals for the sea's multi-billion-dollar fix, though exactly where the money went wasn't made clear.

“We've spent more than half our bond money … We don't have much to show for it, frankly,” said Kimberley Delfino, California program director of the national nonprofit Defenders of Wildlife.

“This is shameful and frightening,” Delfino said. “When you've lost 95 to 98 percent of the wetlands in California, the birds don't have any other place to go. The situation at the Salton Sea is grim and the stakes are high. We need a new governance structure, now. There isn't a lot of time left.”

As for the immediate next step, Pérez said he hopes for a meeting between Defenders of Wildlife, the Salton Sea Authority, the state's Legislative Analyst's Office, and other stakeholders.

“The sea still has its strong supporters, fighters and believers,” Wyatt said. “There are ways to make the revenues happen.”

Mudslide Clean-Up Continues; Highway 395 Open



Thunderstorm-caused mudslide at Dunmovin, California, pushes a big rig off the northbound U. S. Highway 395 and into a culvert on Thursday, August 26, 2010. Video captured by Jeff Bradshaw of Laguna Niguel shows mud flowing from the southbound lanes and across the divided highway.

Sierra Wave


After last Thursday's horrendous flood and mudslide across Highway 395 south of Olancha, Caltrans and others have worked constantly to clear the highway and now to free a big rig that was pushed down into a culvert by the flood.

Susan Lent, PIO of Caltrans, said that the roads are open, but there is a lot of clean-up to do. Intermittent lane closures continue as crews work to clean things up.

Lent said that an Incident Command meeting would take place at the mudslide site on Tuesday among representatives of Caltrans, the CHP, BLM, the Forest Service and DWP. Officials planned to discuss completing clean-up and removal of the big rig which is blocking a culvert.

The initial mudslide had caused complete closure of Highway 395 for several hours. Some motorists headed back to Ridgecrest and detoured through Death Valley although initially Highway 190 was closed due to flooding.

Crews were able to restore northbound and southbound traffic flow, although restricted, by Friday.

Hoover Dam's Perpetual Power

Franklin Roosevelt's signature project created more than jobs and energy—it incited one of our nation's greatest transformations

By MICHAEL HILTZIK
Wall Street Journal


Seventy-five years ago this summer, President Franklin Roosevelt journeyed west from Washington to place the New Deal's indelible stamp on an outstanding symbol of governmental might.

The occasion was the official dedication of what is today known as Hoover Dam. As FDR told 10,000 spectators at the Colorado River dam site and 20 million more via radio, the dam meant gainful employment, cheap hydroelectric power, reliable irrigation and protection from the obstinate elements, all ripped from a forbidding desert canyon by the hand of a visionary federal government. Eleanor Roosevelt, who accompanied her husband on his visit to the Colorado River, would tell friends that the trip brought home to her the sweeping achievement of his administration as if for the very first time. That the project had originated with Republicans—indeed, it was originally conceived by her own Uncle Theodore—went unmentioned.

It is customary to think of Roosevelt's New Deal as the driver of the social and economic changes that gripped America after 1945. But this transformation really began a decade earlier, when the completion of Hoover Dam heralded a period of explosive industrial development and population growth in the West that would reverberate nationwide. The story of America in the last half of the 20th century should be seen as the story not of the postwar era, but the post-dam era.

The dam did more than contribute to the physical and economic remaking of its region; it prefigured and inspired a fundamental change in American values—political, ideological, even psychological. The path from an America of self-contained localities, each one trying address its problems and needs in local isolation, to one in which every state or local issue is seen as a piece of a broad national agenda points us back to Hoover Dam.

Yet the history of Hoover Dam warns us, too, that the nationalization of regional public works can come at a cost. As the Sept. 30 anniversary of FDR's dedication approaches, the country is debating, even more vehemently than it did 75 years ago, the place of the federal government in our lives. It was people's concerns about ceding their personal relationships with doctors to a remote government bureaucracy that animated the opposition to the health-care reform bills in Congress. State and municipal officials complain about the strings that almost always come attached to federal program funding—whether it's minimum benefit standards imposed on federally subsidized health and relief programs, or wage or employment rules attached to federally funded public works.

Then there's the infiltration of national politics into local contracting. Consider the case of a $54 million rail project in California's Napa Valley, which went, without competitive bidding, to a contractor owned by an Alaskan Native American tribe in 2008 because of a preference written years ago into federal law by former Sen. Ted Stevens of Alaska.

These sorts of conflicts and concerns will only become more common as the federal government takes more of a role in upgrading the nation's infrastructure, whether through stimulus funding or by other means. As the Government Accountability Office determined in 2008, the vast majority of the nation's roads and highways are owned by state and local governments, as are the nation's bridges, ports, transit lines and water systems. Few of these can be repaired or even maintained without some federal funding. Indeed, it is hard to conceive of a major public construction project that can be launched without a huge federal appropriation, whether it is an aqueduct, flood-control levee, highway or transportation link.

Hoover Dam made the West but also confined it in a straitjacket. The growth of such great regional urban centers as Los Angeles, San Diego, Phoenix, Salt Lake City and Denver was driven by the water and hydroelectricity it promised. But the millions of residents drawn to those metropolises over the decades have had to confront the realization that its promise was equivocal. Today the Colorado River cannot provide enough water to fulfill all the expectations that the building of Hoover Dam excited in the seven states of the river basin. Even taking advantage of its actual capacity comes at a price—as the federal government controls the water, states and smaller communities must cede to it a large measure of control over their own politics and policies.

The dam that would wield national influence was born in a quintessentially local crisis: a series of floods that devastated Southern California's Imperial Valley in 1905.

The valley had been converted from an arid desert into an agricultural Eden by water irrigated from the Colorado via a 50-mile canal. When the river burst its banks that winter, the private company managing the canal proved itself unequal to the engineering challenges and the financial demands it entailed. The Southern Pacific Railroad stepped into the breach, rescuing the valley from almost certain catastrophe at a cost of some $3 million. But the episode underscored for conservation-minded President Theodore Roosevelt—at a time when "conservation" connoted not only the preservation of nature, but the exploitation of natural resources—that the U.S. government alone could marshal the resources and the authority to manage the river for the public good. In 1907 he proposed that the government undertake "a broad, comprehensive scheme of development" for the Colorado "so that none of the water of this great river which can be put to beneficial use will…go to waste."

Roosevelt's successors expanded on his vision, to the point that Woodrow Wilson's interior secretary, Franklin K. Lane, would proclaim in 1916 that "every tree is a challenge to us, and every pool of water and every foot of soil. The mountains are our enemies. We must pierce them and make them serve. The sinful rivers we must curb."

The Colorado was the most sinful of rivers, unpredictable and destructive in its violent moods. In the 1920s, curbing it became a Republican cause, promoted in Congress by Sen. Hiram Johnson of California, whose Boulder Canyon Project Act was signed into law by Calvin Coolidge in 1928.

Even then, the government's traditional fiscal conservatism stood in the project's way. Federal spending, focused largely on the nation's standing Army and Navy and the payment of obligations incurred in wartime (such as interest on war debt and the upkeep of veterans), amounted to roughly 2% of gross national product. By the end of the 20th century, that figure would be closer to 20%.

What changed the political calculus was the onset of the greatest economic crisis in modern history. By 1930, President Hoover was contemplating a vast increase in federal public works spending to combat unemployment. The problem then was the dearth of "shovel-ready" projects to absorb the additional money. Only one stood out, already authorized by Congress, approved by Calvin Coolidge, and nearly designed and engineered: the great dam on the Colorado.

Hoover's successor, Franklin Roosevelt, instinctively recognized the power of great public works to inspire and encourage. Within a year of his 1935 dedication, three more dams would be under construction in the West, all ranking with Boulder Dam as among the world's grandest. (The dam was christened with Hoover's name by his friend and interior secretary, Ray Lyman Wilbur, at its 1930 groundbreaking, renamed "Boulder Dam" by the Roosevelt Administration, and restored to its original name by a Republican Congress in 1947.) The New Deal's Tennessee Valley Authority would eventually encompass 29 hydroelectric dams. FDR began to see himself as the nation's premier dam builder, calling constantly for more projects, like a man under a spell. Seven more dams would rise on the Colorado itself, exploiting it so completely that its once mighty flow into the Gulf of California has been reduced today to a brackish dribble, runoff from Mexican farms.

Hoover Dam inspired more than irrigation works. Even before its final concrete was poured, construction of the Golden Gate Bridge was under way, involving some of the same contracting firms working in the Colorado gorge. The power of America's concerted will and financial resources, demonstrated so decisively by the raising of the dam in such inhospitable conditions, would continue to assert itself over the succeeding years. This was true in times of acute crisis, as after Pearl Harbor, at D-Day, and in the Manhattan Project; and in times of more placid if not entirely tranquil aspiration, as during 1950s and 1960s, which bequeathed us the interstate highway system and the moon landing.

The rationale for nationalizing public works is largely a sound one: in our mobile, interconnected world even regional infrastructure projects produce nationwide benefits. Westerners and Easterners, Northerners and Southerners fly in and out of each others' airports and ship and receive goods over roadways and rail lines binding the nation together from the rocky coast of Maine to the Pacific shore. Who would begrudge the coastal communities of Louisiana, Mississippi, Florida, and Texas the federal assistance contributed to the efforts to combat the Gulf of Mexico oil spill?

But as the residents of the West well know, the price is a loss of local self-determination. The Colorado River Compact—the interstate treaty that cleared the way for Hoover Dam in 1922 by balancing the water rights of the seven states of the Colorado basin—created a precedent for federal oversight of the river. But its full implications did not become clear until four decades later, with the Supreme Court's 1963 ruling in Arizona v. California.

In that decision, nominally concerned with a dispute between those two states over water rights on the Colorado, the Justices awarded the authority to apportion surpluses and shortages from federal reclamation projects to the Department of the Interior. Farm regulations, urban growth policy, industrial development—on these and myriad other issues, any state that depended on water from a federal reservoir henceforth would have to defer to Washington. This was so astonishing an expansion of federal power over the states that the liberal Justice William O. Douglas excoriated the majority for what he labeled "the baldest attempt by judges in modern times to spin their own philosophy into the fabric of the law."

And so Hoover Dam, born in an effort by Southern California farmers and ranchers to bring willful nature under control, became the instrument by which they ceded control over their destinies to a higher governmental authority. A new set of internecine conflicts over water—between cities and farms, big cities and small towns, wet regions and arid zones—would be decided not in the chambers of state capitols and city halls, but in Washington, D.C. That situation continues to this day: For the citizens of the seven states of the Colorado watershed, the most important cabinet appointee in any new administration is not the secretary of defense or state, but the secretary of the interior.

For all that, Franklin Roosevelt envisioned the Boulder Canyon Project in a way that his predecessor Herbert Hoover would have found entirely alien: as a symbol. The dam signified not only man's mastery over nature, Roosevelt observed, but also a people's ability to find greatness by coalescing into a social and economic community.

Roosevelt was fully alive to the totemic significance of what he called "the greatest dam in the world," its elegant machine-like beauty and alabaster majesty. He understood the spell it would cast on every visitor: Hundreds of thousands of visitors had preceded him, peering over the canyon rim during the construction phase at the ant-like workers 700 feet below; afterwards, a million tourists a year would heed his call "to come to Boulder Dam and see it with your own eyes."

Movie companies would set their melodramas against the improbable backdrop of the exploding cliffsides and pouring concrete; novelists would nudge their plots into motion with mysterious events unfolding in the dam's shadows; advertisers would pose their models against its elegant lines; poets would sing of its flawless beauty.

The United States after the construction of Hoover Dam was very different from the United States that built it. The nation was transformed from one that glorified individualism into one that cherished shared enterprise and communal social support. Public construction projects put millions of people to work creating long-lasting community improvements—hospitals, schools, parks and bridges such as New York's Triborough (now Robert F. Kennedy Bridge) and the San Francisco Bay Bridge. From the end of the war to the 1970s, America's economic growth was broad-based and income inequality suppressed, and socially inclusive federal policies such as civil rights, affirmative action and Lyndon Johnson's Great Society were enacted with popular, if not unanimous, support.

To be sure, that change was not all the making of the dam itself; Social Security, the Works Progress Administration, and other New Deal programs forged in the crucible of Depression all played an essential role, as did four years of war. But the dam remains the physical embodiment of this great transformation, a remote regional construction project reconfigured into a symbol of national pride.

Grand Canyon flood results erode

Some of the sandbars and beaches built up in the March high-flow release are back to pre-flood levels.

By CYNDY COLE
Arizona Daily Sun


A half-year after a manmade flood built bigger sandbars and beaches in the Grand Canyon that are boon to native fish and plants, U.S. Geological Survey researchers say beaches are again eroding.

The data at this point is incomplete, researchers say, but some of the photos to date point to eroding sand bars as water releases from Glen Canyon Dam vary to meet peak power demands and interstate water-sharing agreements. A group of federal agents, tribes, environmentalists and power agencies that advises the Interior Department on how the Colorado River in Grand Canyon should be managed is meeting in Flagstaff Tuesday and today to discuss the latest research and propose next steps.

A budget up for discussion by the group today could determine whether there are any more experimental floods in the next five years. The next one called for in an earlier report by the Bureau of Reclamation is not until 2012.

About $3.3 million is projected to be spent on USGS research related to the flood this year and next.

The amount of sand in the Colorado River is of interest because it is believed to be linked to the creation of backwaters that could help promote the survival of some fish species, and because boaters use beaches for camping.

All of the sand that once flowed into the lower Colorado River upstream of Lake Powell is now trapped by the dam, leaving it to the remaining tributaries to supply sand to the main channel during periods of high water.

The advisory group did some battle publicly this spring, when Grand Canyon Superintendent Steve Martin proposed more regular floods to improve the canyon's ecosystem, to the disagreement of power producers and his bosses.

The floods are conducted as part of an experimental program to manage the Grand Canyon ecosystem to allow for power generation at the dam, while offsetting the dam where possible.

USGS researchers say it is possible to maintain some sandbars and beaches along the Colorado River with the dam in place.

But for that to happen, according to researchers' findings, power production would often suffer.

Environmental groups, including the Grand Canyon Trust, have litigated over dam operations, saying what's beneficial for peak power production puts some of the canyon's few remaining endangered fish species in jeopardy.

Trust employee Nikolai Lash, who works on this issue, said it's hopeful that the coming presidential election could change the Colorado River.

"The orientation has been completely backwards," he said. "This dam has been operated not for the benefit of Grand Canyon, but for the benefit of hydropower interests."

The third experimental flood since 1996, the March experiment was timed to move around three times more sand than was available in the tributaries to the Colorado River in 2004.

County funds repairs for ‘railroad bridge’

Residents still waiting on Rock Springs Road motorist bridge

VICTORVILLE — With no word on a Rock Springs Road “bridge” to bypass the Mojave River during flood season, the San Bernardino County Board of Supervisors Tuesday approved $100,000 to repair the railroad bridge just north of the road.

For years Rock Springs Road — connecting unincorporated Apple Valley to Hesperia — was washed out during heavy rains, cutting off at least 11,000 motorists who use the road daily.

In 2005, the county constructed a new reinforced concrete culvert underneath Rock Springs Road, which diverted some of the river’s flow toward the railroad bridge, causing damage, said David Zook, spokesman for San Bernardino County 1st District Supervisor Brad Mitzelfelt.

The affected portion of the railroad structure now must be reconstructed by using deeply driven steel piles to replace the original timber piles, according to the Board of Supervisors’ agenda.

The county will contribute $100,000 from the County Road Funds budget to the railway project. In return, BNSF will design and construct the project and release the county from liability for any further damages to the affected portion of the railroad bridge.

“A request for funding to construct the (motorist) bridge for Rock Springs Road has been a part of our federal legislative platform for several years,” Zook said.

As recently as January, Rock Springs Road was closed for more than a day due to flooding. However, since the construction of the new culvert the road hasn’t been “washed out” and reopens as soon as water recedes, Zook said.

The San Bernardino County Public Works Department estimates that the road has been closed five times since 2005 as a result of flooding.

The 2005 project was built with $1.1 million in federal funds awarded in response to the flooding, and the county was prohibited from using it for any reason other than simply repairing the road, Zook said.

In a previous interview Mitzelfelt said he has been wanting to build a bridge over the river on Rock Springs Road since he was appointed, but the cost is too high.

Original estimates to build a permanent bridge when it was washed out in 2004 came in at $15 million.

Zook said the county has requested a $2 million earmark from its congressional delegation to get the project started and estimates the entire project will cost $20 million.

“However, the appropriations have not been made yet and we don’t expect Congress to complete that process until after the presidential election,” Zook said.

Woman killed in flash flood in San Bernardino County identified

by Richard Brooks
Press-Enterprise


The motorist killed during last night's flash flooding near the Colorado River was a 51-year-old woman from Big River, according to San Bernardino County coroner's officials.

Rosemary Sebring Genc was pronounced dead soon after being pulled from her 1990 gold Honda Accord. A county road worker said he saw her drive into a flooded area at 9:15 p.m. Monday near Rio Vista Road and Tenaya Court. The water pushed the car to the edge of the roadway where it overturned in a wash, trapping the woman underwater, coroner's investigators said.

Flash flooding in the same general region also closed portions of Highway 95 from Vidal Junction south to Interstate 10 in Blythe. At 3 a.m., heavy rain had limited visibility to 20 feet in some places, according to the California Highway Patrol website.

With forecasts of possible thunderstorms and flash flooding through this weekend, officials point to the apparent drowning death as an example of the dangers of driving through floodwaters.

"Turn around. Don't drown," says the written warning issued Tuesday.

"Despite repeated warnings, some people continue to risk their lives by driving through running water," county analyst Roni Edis said in a written statement. "Be aware of flood hazards, no matter where you live."

PHOENIX — Rescue crews have located a handful of hikers who were missing after flooding struck a remote part of the Grand Canyon, authorities said today.

The 11 people from two families were tracked down in the canyon on Monday, Coconino County Sheriff's Department spokesman Gerry Blair said. They were the last to be accounted for after creeks overflowing with runoff from severe thunderstorms washed away trails during the weekend, stranding dozens of tourists.

"We have met them, and they're OK," Blair said.

Authorities were receiving more calls from people who believe their loved ones may still be in the canyon, Blair said. But everyone who followed the rules and signed in at the bottom of the trail into the remote area had been evacuated.

Rescue crews checked the hiking trails and surrounding gorges by helicopter and foot again today, and crews will do a more comprehensive ground search when the flood waters recede in a few days, Blair said.

Helicopters ferried about 255 people out of the canyon Sunday and Monday from the Havasupai Tribe's village of Supai, a remote community near the bottom of the canyon in an area west of Grand Canyon National Park headquarters. Many of the stranded tourists made their way to Supai before catching a helicopter ride to the rim.

Thunderstorms dumped 3 to 6 inches of rain on the entire region Friday and Saturday and about 2 inches more on Sunday. The storms sent a rush of water through parts of the canyon, uprooting trees and washing out trails and footbridges.

Mimi Mills, 42, of Nevada City, Calif., was stranded with 15 other river runners Saturday afternoon after a flash flood washed away their rafts. Mills said the group took shelter overnight under an overhang, but had to scramble up a cliff when another flash flood occurred in the middle of the night.

The Havasupai tribe is one of the smaller Indian communities in Arizona with some 679 members, according to Bureau of Indian Affairs estimates from 2003, the latest statistics available.

The tribe's Supai village sits in a region that's popular for hikers and river runners, with towering blue-green waterfalls. About 400 people live there year-round.

No one needed to be rescued, and all of the vehicles were able to get out by the time officials arrived.

It Was 'Crazy' Out There

Storm left stores flooded, drivers stranded, mother and son hurt by lightning

By MAGGIE LILLIS
Las Vegas REVIEW-JOURNAL


Boys play in floodwaters Thursday after a storm dumped varying amounts of rain over the southern valley.

After weeks of do-nothing clouds and teasing humidity, the valley was pounded by a storm cell Thursday that forced road closures, stranded motorists and left a Henderson boy and his mother injured by a lightning strike.

More than 3 inches of rain fell in some mountain areas, but only about 0.16 inches accumulated within the valley, the National Weather Service in Las Vegas reported.

Meteorologists at the weather service's offices experienced the brunt of the storm without some of their radar equipment, which was struck by lightning during the action.

But the heavy rain added only a few drops to the annual total, which now stands at 1.04 inches.

"Normally at this time of year we are at 2.92 inches. We are definitely below the average," said meteorologist Edan Lindamen.

The powerful storm swept across the southern part of the valley, flooding businesses and creating swift-water rescue situations for emergency responders in Henderson and elsewhere.

State Route 160 was closed for about an hour after 3.05 inches of rain fell near Mountain Springs. Backups also occurred on U.S. Highway 95 and on Boulder Highway, where some spots were under 2 feet of water and stranded motorists had to be rescued.

The storm didn't just make its mark with rising floodwaters and muddy debris.

A lightning strike in Henderson knocked a 4-year-old boy unconscious and left his mother with temporary numbness on one side of her body.

Henderson Deputy Fire Chief Steve Goble said the woman and her son were watching the rain from the front lawn of their home near Green Valley Parkway and Warm Springs Road when lightning struck nearby about 3:20 p.m.

Goble said the "ground surge" apparently knocked the boy out and caused the woman to experience some paralysis on one side of her body. But both of them "came out of it" as they were treated at the scene by paramedics, he said.

They were sent to the hospital for observation.

Henderson firefighters also rescued a 12-year-old boy from a wash near Patrick Lane and Stephanie Road. Goble said the boy was pulled from the water unharmed.

"The report was he was skateboarding down there," Goble said. "He was having a good old time, until the water came."

The Henderson Fire Department received several other reports of people in the water, but no other rescues were needed.

The storm also brought a flurry of reports of fallen trees, electrical fires and "four or five dozen stranded vehicles," Goble said. "It's been crazy."

Businesses also got caught up in the storm.

The Circle K convenience store and gas station near Tropicana Avenue and Andover Drive closed for a few hours when an inch of water crept inside. Employees said this has happened five or six times in the past as they swept about a foot of cloudy water around racks of potato chips and newspapers.

Officials with the Clark County Regional Flood Control District said their gauges reported almost 2 inches of rain falling within 30 to 40 minutes in areas near Henderson.

The weather service in Las Vegas said more storms are possible today. Conditions will start to dry out by the weekend, it said.

Wind rips off roof








By Jimmy Biggerstaff
Hi-Desert Star







MORONGO BASIN — Heavy rain in Twentynine Palms and the Joshua Tree National Park Monday caused road closures, washouts and wind damage to several structures.

A powerful and well-formed dust devil took the roof off a house on Ocotillo Road in Johnson Valley about 2 p.m. Monday, including plywood and cross members on one side. The home’s carport also was damaged.

John Jones, a local emergency medical services volunteer, was about a mile away from the meteorological oddity, and confirmed it was not a tornado. Jones described the funnel as about 250 feet high and 300 feet wide.

The thermal originated from the ground, not from clouds, Jones said.

Johnson Valley’s fire station sustained damage to a light fixture and television antenna.

Megan Blaney, a public information officer with the San Bernardino County Fire Department, said the emergency operations center [EOC] in Rialto was activated in response to an emergency declaration by the City of Twentynine Palms.

The EOC was still active Tuesday afternoon.

Robert Eland, the field representative for county supervisor Brad Mitzelfelt, was at work in Twentynine Palms Tuesday assessing damage to help determine how San Bernardino County could best help Twentynine Palms with clean-up and recovery efforts.

Park closes road, camps

Strong thunderstorms across the north central area of Joshua Tree National Park damaged a number of park facilities. The storm forced park officials to temporarily close a number of park facilities. Roads and camping areas affected by the closures are open to day-use hiking.

Due to flash flood damage, the following park facilities are closed until further notice:

The Indian Cove Area, including;

  • Indian Cove Road south of Indian Cove Ranger Station

  • Indian Cove Campground

  • Indian Cove group campsites

  • Rattlesnake Canyon Day Use Area
Additionally, Park Route 12 is closed from the park’s North Entrance south five miles to the Pinto Wye Junction.

While 0.77 inches of rain were recorded at park headquarters in Twentynine Palms, rangers estimate that storm-affected areas in the park may have received from 3 to 5 inches of rain

Torrential floodwaters were observed crossing one section of park road just south of the North Entrance, resulting in the complete loss of 30 feet of roadway, according to Joe Zarki, the park’s public information officer.

The North Entrance Road will be closed for about 48 hours while temporary repairs are made, Zarki wrote in an e-mail Tuesday.

In the Indian Cove area, floodwaters scoured steep drop-offs along the edges of about one-third of the road leading to Indian Cove Campground and significant flood damage occurred in portions of the campground as well.

Park service officials estimate it will take about two weeks to make the necessary repairs before the Indian Cove Campground and Indian Cove Road can be reopened for public use.

The park’s other main entrances, the West Entrance, five miles south of the community of Joshua Tree, and South Entrance, near Interstate 10, remain open for public use.

Park trails are open, but hikers and equestrians should exercise caution as many trails have not yet been assessed for flood damage.

“Please observe all road closures,” Zarki said. “These have been put in place for your safety.”

Strong storms pound San Bernardino County







The Associated Press
San Jose Mercury News







TWENTYNINE PALMS, Calif.—Strong storms have pounded the area around Twentynine Palms in San Bernardino County, causing widespread flooding, road closures and power outages.

KCDZ-FM in Joshua Tree reports heavy rain began pelting the area around noon Monday. The station says firefighters rescued a woman whose vehicle got stuck in water and mud on Morongo Road at Indian Trail near the back gate of the Marine Corps Air Ground Combat Center.

The station says strong winds blew the roof off of a carport in Twentynine Palms. Lightning strikes also left parts of Twentynine Palms, Amboy, Yucca Valley, Johnson Valley and Landers without power. Southern California Edison crews are working to restore service.

Mojave River Flooding closes Rock Springs Road


2,400 gallons of water per second being released

ROCK SPRINGS — Rock Springs Road has been over taken by Mojave River flood waters and now looks more like a lake, cutting off at least 11,000 vehicles per day who use it.

Due to the recent heavy rains more than 366,000 gallons of water per minute is being released into the Mojave River, which has caused the closing of Rock Springs Road.

The low-lying road which connects Apple Valley to Hesperia is often flooded out during heavy rains.

The recent storms caused the California Department of Water Resources to release water from Silverwood Lake.

“Cedar Springs Dam is not a flood control dam so any natural resources that come in, we have to let out,” said John Bunce, operations superintendent for the department.

Starting Sunday, the department began releasing 320 cubic feet of water from the dam per second, or 2,400 gallons.

By Sunday night it was up to 4,500 gallons per second being released, said David Zook, spokesman for San Bernardino County 1st District Supervisor Brad Mitzelfelt.

Monday morning they increased the flow again up to 815 cubic feet per second, or 61,000 gallons, Zook added. It will continue at that rate indefinitely he said.

The Cedar Springs Dam holds water in Silverwood Lake. The lake is a state water project retaining water from the California Aqueduct.

“That water belongs to us, not the state water project,” Zook said of the natural rainfall.

The Mojave Forks Dam, located further down river from Silverwood lake but still before Rock Springs Road was reportedly releasing 5,700 cubic feet of water per second Sunday or 42,750 gallons of water.

The National Weather Service released a flood warning Sunday saying significant water was expected to be released into the Mojave River.

As a result of the alert, Mitzelfelt initiated the telephone emergency notification system to alert residents in the area of the possible flood dangers.

Zook said about 3,000 residents were notified.

Monday afternoon, eight inches of water was still flowing over Rock Springs Road, Zook said.

Zook said public works officials didn’t expect the road to be badly damaged from the flooding.

According to the San Bernardino County Department of Public Works, no other roads down stream required closure, due to the water being released.

Mitzelfelt said he has been wanting to build a bridge over the river on Rock Springs Road since he was appointed but the cost is too high.

Original estimates to build a permanent bridge when it was washed out in 2004 came in at $15 million.
