Auburn Dam a Torrent of Doubts Tempting fate: A torrent of doubts Project backers expect electricity, water and flood protection, but critics call it pie-in-the-sky By Matt Weiser -- Bee Staff Writer Published 2:15 am PST Sunday, February 19, 2006 Story appeared on Page A1 of The Sacramento Bee American taxpayers have had an unsteady relationship with the Auburn dam: $400 million spent so far on a dam that was never built; another $30 million through the end of this year to restore the former construction site; and now $1 million more to study whether to build the dam after all. Since Hurricane Katrina swamped New Orleans, Auburn dam supporters have rallied behind the project anew, suggesting it should be revived to protect Sacramento from a similar disaster. The debate over the dam has always been politically charged, but an analysis by The Bee found an Auburn dam also could be an expensive mistake. Tony Firenzi, an engineer with the Placer County Water Agency, stands in the midst of the Auburn dam constrcution site, where work was Supporters want to build a multiuse dam, which would rely halted decades ago. on water sales, hydroelectric power and recreation fees to Sacramento Bee Photo, Bryan Patrick offset a likely cost of $5 billion. But as a reservoir, an Auburn dam would create a limited new water supply, producing too little water and electricity to pay for itself, and at prices one potential buyer likened to champagne. And that's only the beginning of the contradictions between dream and reality. "It has become kind of like a religious site," said Butch Hodgkins, a member of the state Reclamation Board who once lobbied Congress for the dam as executive director of the Sacramento Area Flood Control Agency. "The dam is incredibly controversial because it runs flat into the fundamental beliefs of fiscal conservatives and environmentalists. It is, in effect, financially and politically impossible at this time, so you better get a good pair of water wings, or you better find something else." Earth-moving equipments sits silent, above, at the site of the Auburn dam’s east foundation, where construction stopped in 1979. For more than two decades, Rep. John Doolittle, R- Sacramento Bee Photo, Bryan Patrick Roseville, has led the Auburn dam faithful. It was he who persuaded the government to spend $1 million on another dam study by attaching it to an energy and water appropriations bill in November. In an interview Friday, Doolittle dismissed every criticism of the dam, from earthquake risk to the cost of the water it would provide. "Any dam will eventually pay for itself," Doolittle said. "If you build a multipurpose dam, it's a moneymaking machine because it generates the sale of electricity and of water. The project is alive and well, and it begs to be completed." But most water and flood-control experts consider the Auburn dam a fantasy. "It's a dam that makes no economic, environmental or flood-control sense, given the realities of California's water situation," said Peter Gleick, president of the Pacific Institute, an independent water- policy think tank in Oakland. "The attraction of building big concrete things is palpable. But it's just no longer realistic, and it's no longer necessary." The Auburn dam may end up being the most expensive dam that never was, with $400 million and counting spent since the project was authorized by Congress in 1965. Earthquake risk halted the project in 1979, leaving behind a gravel pit where a wild left-hand bend in the river used to flow. The dam's problems, culled from dozens of interviews and thousands of pages of public records reviewed by The Bee, include the following: * Auburn dam capacity could reach 2.3 million acre-feet of water, but it would be able to sell, at most, 350,000 acre-feet in an average year because someone else owns the rest. Although this could serve 700,000 homes, a recent state study found that California can meet its needs through 2030 by maximizing conservation and recycling, producing five times more water than an Auburn dam at a fraction of the cost. * Water out of an Auburn dam would be very expensive. A decade-old federal study estimates it could cost almost $1,000 per acre-foot; dam supporters say it could run to $2,000 per acre-foot. The going rate for water today rarely exceeds $500 per acre-foot. * It would be the most costly dam in American history. Supporters use $3 billion as a working estimate; others say $5 billion. The U.S. government pays only 65 percent of the flood-control portion of a new dam, requiring a local sponsor to pay for everything else. There is no local sponsor. * The dam faces numerous environmental obstacles. In 1996, the U.S. Geological Survey said earthquake risk may be far greater than originally thought. And the dam might hurt recreation more than it helps because an average of 1 million people a year now enjoy the canyons that the dam would submerge. Economic challenges An Auburn dam's biggest challenges have always been economic, in part because its location, just east of the city of Auburn, was never a great place for a dam. The best spots allow a small dam that creates a vast reservoir. Hoover Dam on the Colorado River, for instance, blocks a narrow slot canyon, storing 28.5 million acre-feet of water. Auburn dam would be as tall as Hoover, but more than three times as wide. Yet it would store just 8 percent of Hoover's water because the canyons behind it are so short and narrow. William Graf, professor of geography at the University of South Carolina, has assembled one of the most extensive inventories of American dams. He said that by 1980, the United States was built out in terms of dams, with all the good sites taken. More recently, the nation has gone the other direction, demolishing an average of 100 dams annually. "That's the context Auburn dam is still floating around in," Graf said. "I would say it's swimming upstream." Even one-time potential customers are no longer interested. East Bay Municipal Utility District was among the potential buyers of Auburn dam water 40 years ago, when the dam was a $280 million proposal that would have been funded entirely by federal taxpayers. During a hearing at the Legislature in the early 1990s, utility district lobbyist Randy Kanouse recalled, "Not a single utility in the state would get up to testify in support, because of the fear that there would be some expectation created that they were prepared to contract for water out of that reservoir." "All of them said at the time that it's way too expensive," Kanouse added. "It's like champagne behind that dam and it's too rich for our blood." In the ensuing years, the East Bay district has found other ways to meet its water needs, including a diversion canal on the Sacramento River at Freeport, and a seawater desalination project. Both are cheaper than buying water out of an Auburn dam. As a water supply machine, Auburn dam is disappointing in another way: though it can pose a mean flood threat, the American River is not a very rich or reliable water source. A 1991 study by the U.S. Army Corps of Engineers estimated the average annual runoff from the watershed behind the dam at a modest 1.6 million acre-feet. Most of that already belongs to someone else. "The American is a very highly engineered system, and it captures the bulk of the (water) yield out of that watershed," said Barry Nelson, a senior policy advocate with the Natural Resources Defense Council. Nelson, like other environmentalists, is hardly unbiased about dams. But studies show he is right about the water supply. There are about 20 dams in the American River watershed, which store 75 percent of the average annual runoff. As a result, a 1987 study by the U.S. Bureau of Reclamation estimated a multipurpose Auburn dam could deliver, at most, 350,000 additional acre-feet of water in an average rainfall year. That means only about 15 percent of an Auburn dam's capacity would be available for sale. In comparison, 50 percent of Folsom Dam's capacity is available for sale, even though that reservoir is half as large. The volume of water affects the dam's ability to generate electricity. If the dam can't maintain a high water surface elevation because of limited storage or inflows, water pressure through the hydroelectric turbines is reduced, limiting their power output. This means an Auburn dam might not generate as much revenue from electricity as supporters hope. Though its turbines could be capable of producing 400 megawatts - enough to power 400,000 homes - dams typically operate at less than 50 percent efficiency because of changing water levels and other conditions. A loss of recreation As a recreation destination - another element proposed to offset the dam's cost - Auburn dam also falls short. Supporters say the dam could draw more than 1 million visitors a year for boating and fishing. But the 42,000-acre state park that would be inundated by the dam already draws 1 million visitors a year. Growth in foothill towns and changing demographics are driving new recreation patterns that favor hiking, running, horseback riding, biking, rafting and kayaking. Many of these visitors, who already contribute to the local economy, would be displaced by a dam. Yet, with two narrow arms, the reservoir would be unlikely to become an ideal destination for other forms of recreation, such as water skiing.

  • The Great New Year's Flood of 1997 in Northern California
    The Great New Year's Flood of 1997 in Northern California by Maurice Roos' The New Year's flood of 1997 was probably the largest in the 90-year Northern California record which begins in 1906. It was notable in the intensity, volume of flood water, and the areal extent from the Oregon border down to the southern end of the Sierra. Many new flood records were set. This was a classic orographic event with warm moist winds from the southwest blowing over the Sierra Nevada and dumping amazing amounts of rain at the middle and high elevations, especially over a 3 day period centered on New Year's Day. The sheer volume of runoff exceeded the flood control capacity of Don Pedro Dam on the Tuolumne River and Millerton Reservoir on the upper San Joaquin River with large spills of excess water. Most of the other large dams in northern California were full or nearly full at the end of the storms. Amounts of rain at lower elevations were not unusual. For example, downtown Sacramento in the middle of the Central Valley had 3.7 inches during the week from December 26 through January 2. But Blue Canyon, at the one-mile elevation between Sacramento and Reno, had over 30 inches, an orographic ratio of over 8, far more than the usual 3 to 4 for most storms. Many Valley folks could not understand that there was a problem because they were not seeing a lot of rain. Meanwhile, the entire northern Sierra was observing 20 inches, some 40 percent of average annual precipitation.

  • Chapter 7: Alternative Evaluation
    Chapter 7 Alternative Evaluation The potential for water quality improvements in the Delta was evaluated in terms of the position of X2 and the resulting Delta outflows. Shifting X2 downstream improves the habitat for Delta smelt and reduces water quality stress for other species, including salmonids. X2 is a Delta management tool; it is defined as the distance in kilometers from the Golden Gate Bridge to the location where the tidally averaged near-bottom salinity in the Delta measures 2 parts per thousand (ppt). East of X2, water becomes progressively fresher, and west of X2 the water becomes more saline, until it reaches the ocean, which has a salinity of approximately 35 ppt. Habitat quality in the Delta is degraded when the salinity in the Delta increases. The highest salinities occur during the fall and early winter, when Delta outflow is at its lowest. Water quality degradation is most pronounced in Dry and Critical years. Figure 7-8 shows the change in the average X2 positions during September and October in Dry and Critical years for each of the alternatives. Alternative C performs best in terms of the shift in the location of X2 by 0.3 to 1.0 kilometer (km) seaward, followed by Alternative B and then Alternative A. Alternative D provides the least water quality benefit, with an average shift of 1 km to the east in July through August, and a 0.3 km shift in September through November. Shifting X2 requires a significant quantity of water. Releases from Sites Reservoir to improve Delta environmental water quality range from 174 TAF/yr under Alternative D up to 242 TAF/yr under Alternative C.

But not rare events. • Another dam, Auburn Dam, was partially constructed upstream of Folsom Dam, and it would have greatly increased flood storage capacity upstream of Sacramento on the American River. But it was never completed. • The primary vulnerability for Sacramento’s levees is overtopping. • Pressure from California public and agricultural interests to increase water supply and irrigation is considerable. They want to pass as little water as possible from dams. This pressure is opposed by the need to maintain flood storage capacity. • An overtopping of the levees in Sacramento by river floods may be expected to result in hundreds to thousands of deaths. Such a flood would be a 1 in a 300 event. • As a result, Sacramento has had to develop highly detailed flood warning and evacuation plans. PGS-2 BUILDING STRONG® Presentation Overview .

The Central Valley of California is a magnificent example of this. The Sacramento River watershed receives two-thirds to three-quarters of northern California's precipitation though it only has one-third to one-quarter of the land.

Authorized features of the Auburn-Folsom South Unit include in the following: • Auburn Dam, Reservoir, and Powerplant on the North Fork of the American River • Folsom South Canal • Sugar Pine Dam, Reservoir, and conveyance • County Line Dam, Reservoir, and conveyance Construction on the Auburn-Folsom South Unit was initiated in 1967. Sugar Pine Dam, Reservoir, and conveyance have been completed. Construction of the first two reaches of the Folsom South Canal, about 27 miles, was completed in 1973 but further construction has been suspended. Construction has not been initiated on the County Line Dam and associated features. Construction of the Auburn Dam portion of the Auburn-Folsom South Unit was deferred following an earthquake in 1975 near Oroville. In Section 209 of the Energy and Water Development Appropriations Act of 2005, the Secretary of the Interior was directed to complete a Special Report to update the costs and associated benefits of the Auburn-Folsom South Unit. PURPOSE AND SCOPE The primary purpose of this Technical Memorandum (TM) is to identify those project features included in the authorized Auburn-Folsom South Unit that would be applicable today if it were decided to continue with implementation of the project.

  • Pump Station Project Public Access
    California Department of Parks and Recreation Gold Fields District Auburn SRA Public Access, Use and Facilities associated with the American River Pump Station/River Restoration Project The American River Pump Station Project is located on the North Fork of the American River at the Auburn Dam site within Auburn State Recreation Area. The project has three objectives: 1.) To provide permanent facilities for the Placer County Water Agency (PCWA) to convey its water entitlement to the Auburn Ravine Tunnel; 2.) To eliminate the safety issue with the Auburn Dam bypass tunnel; and 3.) To restore the river to its pre-construction channel to allow all of the beneficial uses of the river in what is now a de-watered channel, including recreation, navigation, fish passage and other beneficial uses. The U.S. Bureau of Reclamation (Reclamation) and Placer County Water Agency (PCWA) are the lead agencies for this project. This project was analyzed and approved through the American River Pump Station Project Environmental Impact Statement/Environmental Impact Report which was completed in June 2002. Project Background Prior to the initiation of the construction of Auburn Dam, PCWA built a pump station on the NF American River to deliver water to the Auburn Ravine Tunnel and the PCWA service area. As part of the Dam construction the Reclamation entered into an agreement with PCWA to provide an interim pumping facility until the Dam was completed and PCWA could divert their water entitlements by gravity from the proposed Auburn Reservoir. Seasonal pumps (removed in the winter) were installed in the Canyon by Reclamation to allow PCWA to take water.
