In Delicate Balancing Act, Folsom Dam May Cut Outflows

In a desperate attempt to avoid a water crisis in the coming months, the operator of Folsom Dam may reduce outflows to the bare minimum necessary to protect spawning steelhead trout in the American River.

Bureau of Reclamation Central California area manager Drew Lessard said his staff was in talks with federal and state wildlife officials to determine how much outflows could be cut without harming the winter run of the trout, a federally-protected species.

At 363 feet above sea level, Folsom Lake has never been so low in January; the dam is currently releasing four times more water than is flowing into the reservoir.

“We’re proposing to reduce our flows into the American River so we can maintain water conservation in the dam,” Lessard said.

Conservation Groups Object To Lack Of Fish Protection In YCWA Relicensing Application

While some groups are excited about what the Yuba County Water Agency’s FERC relicensing applications contains, other groups are lamenting what is missing — namely, provisions that address removing barriers to native spawning habitat for endangered fish.

Numerous conservation groups called for the YCWA to look into developing fish passage through, or removing entirely, Englebright Dam, which is a direct barrier to more than 120 miles of salmon habitat, according to comments submitted by the Foothills Water Network, which represents a group of water resource stakeholders in the Yuba, Bear and American River watersheds.

“The ultimate goal is to restore salmon to their native habitat,” said Tyrone Gorre, co-founder of the Sierra Salmon Alliance. “In order to restore habitat, we have to have passage through the dam.”

Chinook salmon and steelhead and rainbow trout are both native to the upper Yuba River watershed.

The problem with those requests is that the Englebright Dam is not within the FERC boundary of YCWA’s project and is operated by the Army Corps of Engineers.

“There’s not a connection between that dam and the FERC relicensing,” said Yuba County Supervisor Mary Jane Griego. “Some of the river agencies would like to connect those so there’s a requirement for us (to install fish passages), but the FERC relicensing really separates those issues.”

The Foothills Water Network said excluding Englebright from the relicensing process is a mistake, arguing that because YCWA operates its reservoir levels and releases, it should be included in their FERC license.

“We have maintained that fish passage is not part of our FERC relicensing. YCWA facilities don’t block fish passage; the major barrier is Englebright Dam,” said Curt Aikens, YCWA general manager. “We do realize that this is a significant issue in the Yuba watershed, and we’ve helped lead and facilitate different fish passage studies and programs.”

Aikens said the colder water released from the higher elevation of New Bullards Bar dam has helped improve salmon habitat in the lower Yuba River.

The salmon population has recovered since a stark decrease around 2007 caused a temporary halt in the salmon fishing industry, but reported numbers from the Yuba River in recent years are below those of the decades prior.

Placer Water Has 2014 Supply Concerns

The Placer County Water Agency is saying that a good rainfall year is needed in 2014 to restock mountain reservoirs.

And the Water Agency is already looking at the possibility of water-use reductions.

The Auburn-based agency is expressing concerns as a very dry 2013 draws to a close. Tony Firenzi, deputy director of technical services, said a dry 2014 could cause problems.

“Right now, our water storage is at 90 percent of average for this time of year, so we’re in good shape for the time being,” Firenzi said, “but we’re very concerned about the continuing dry forecasts.”

Looking into the coming year’s projections, Firenzi said better-than-average precipitation would be needed to restore average storage levels on the upper Yuba-Bear and American river watersheds. Placer Water depends on the two watersheds for its surface water supplies.

Water storage in reservoirs that serve Water Agency customers has remained at or near average levels despite back-to-back unusual water years. The 2011-12 water year (measured from Oct. 1 to Sept. 30) was dry but ended near average after the so-called “Miracle March” in spring 2012. It was followed by a 2012-13 water year that produced near record precipitation in November and December 2012 but then turned unusually dry.

“In fact, the 2013 calendar year is on track to close as one of the driest ever measured, which is the basis for serious concern as we look ahead at water availability for 2014,” Firenzi said.

Central Valley Salmon Runs Could Be Restored

Salmon advocates say they know how to restore sustainable salmon runs in the Central Valley – 26 different ways.

The Golden Gate Salmon Association says two years of study have resulted in a 26-project salmon rebuilding plan to reverse the steep decline of California’s four salmon runs, including two considered endangered and threatened under the Federal Endangered Species Act — the winter and spring runs.

The fall and late fall-runs, which support the sport and commercial fishery, declined by 90 percent and 87 percent respectively from 2001 to 2011, the association says.

“The salmon problems are not in the ocean but rather in the freshwater rivers where salmon reproduce and then try to migrate downstream through the many hurdles that exist on their journey to ocean waters,” says GGSA Chairman Roger Thomas.

The 26 projects are divided into three tiers to prioritize completion. In April the first eight high priority projects were selected with most underway or in the pipeline for 2014. The second tier is currently being considered by federal agencies for implementation.

The rebuilding plan can be broadly broken into two categories of projects, says the association. The first calls for better flows for salmon in the Sacramento and San Joaquin rivers and the Sacramento-San Joaquin Delta. The second are projects aimed at healing manmade structural impediments built in and along the rivers.

The loss of many baby salmon at the pumping facilities that divert water from the Delta for export south is another problem the GGSA says its plans address.

Folsom Imposes Water Use Restrictions

The Sacramento suburb of Folsom is imposing a mandatory 20 percent cut in water use as the dry winter continues and as the city’s main source of water – Folsom Lake – is 22 percent of capacity.

“This low water level, combined with critically dry weather conditions, necessitates immediate action to conserve water and protect our water supply,” says Folsom City Manager Evert Palmer.

Folsom is the first Central Valley city to impose such restrictions during the current dry spell.

Mandatory water use restrictions for businesses and residences limit landscape watering to two designated days per week; prohibit washing of parking lots, streets, driveways or sidewalks; and prohibit use of city water for construction purposes such as dust control, compaction or trench jetting without approval.

“During cold winter months, landscapes need very little water, making this an easy time of year to achieve significant water savings,” says Folsom Environmental and Water Resources Director Marcus Yasutake. “Approximately 60 percent of the water used by a typical Folsom family is directed to landscape. We’re encouraging residents to turn off sprinklers to conserve water. An added benefit will be significant savings on water bills.”

Those who choose to water are restricted to two days per week and asked to avoid excessive watering that runs off onto sidewalks, street and gutters.

Some Species In Delta Still At Risk From Water Diversion Tunnel Project

Despite a 34,000 page long environmental study, the California Department of Water Resources cannot say exactly what a massive water diversion and habitat restoration program will do to at least nine of fifty Northern California delta species.The irony is that the Sacramento/San Joaquin valley water restoration and conservation project was expected to help endangered species, according to a Dec. 18 Sacramento Bee article.

The giant water diversion project will cost $25 billion and will use three massive tunnels to divert water from the Sacramento River.

The Bay Delta Conservation Plan’s first complete draft was released to the public this week. It will be available for a 120 day public review, notice and comment period.

The environmental impact report was supposed to clear up any issues with affected species, like salmon, cranes, fish and more. There are actually 57 endangered species that might be affected.

The problem is with several “not determined” findings from the U.S. Fish and Wildlife Service and the National Fish and Marine Fisheries Service. These federal agencies are at odds with the State Department of Fish and Wildlife service, which finds a “less than significant” effect on the nine species.

The federal agencies say it is too early to make a final determination. The state appears to be in a rush for approval, but the only support for any conclusions comes from computer modeling.

In other words, until this unprecedented and massive habitat restoration and water diversion project is actually built and operating, no one knows for sure what will happen to individual species or their habitats.

In Other Watershed News: San Joaquin Valley Salmon Make Small Gains Against Tough Odds

With a flash of silver and pink, a male salmon signaled its arrival in a stretch of the Tuolumne River near La Grange.

It sought to fertilize eggs laid in the shallow stream bed gravel by a female that also had returned from a few years in the Pacific Ocean.

Chinook salmon spawning has been going on since September on San Joaquin Valley rivers. It’s a stirring sight for people who love nature, but important as well to farmers and other water users who could face cutbacks if the fish numbers stay low.

This year, at least, they are not doing too badly. Many of the spawning fish were born on the rivers in 2010 and 2011, when the water ran high, and they enjoyed healthy conditions at sea. They return to streams shrunken by drought, but well-timed reservoir releases have provided some of the flows they need.

“This is where they want to be,” said Gretchen Murphey, an environmental scientist for the California Department of Fish and Wildlife, during an early December visit to the La Grange stretch. “This is the habitat they’re looking for.”

As of Monday, 3,607 salmon had passed through a fish-counting device on their way to the Tuolumne’s spawning stretch in the low foothills, up from 2,152 a year earlier, and just 255 in 2009.

Feds May Have Harmed Sacramento River Salmon

The federal agency that regulates water releases from the Shasta Dam in Northern California drastically cut those releases in November, and one fisheries group is afraid that the move could have killed millions of eggs laid by fall-run chinook salmon in the Sacramento River below the dam.

According to the Golden Gate Salmon Association (GGSA), the U.S. Bureau of Reclamation (BuRec) cut releases from Lake Shasta from 6,000 cubic feet per second (CFS) to 3,750 CFS between November 1 and 25. This caused river levels downstream to drop dramatically, which means that any salmon eggs laid in parts of the river that died up will almost certainly be lost.

This isn’t the first year BuRec has cut November water releases from the dam, and those cuts have hurt salmon in previous years. As many as 15 percent of the Sacramento river’s fall-run eggs were lost after a similar move in 2012, and almost a quarter of the run’s 2011 eggs were killed the same way, according to GGSA.

Why do Pacific Salmon Die After Spawning?

The upriver salmon run is one of nature’s great migrations. Each year mature salmon make the long journey back to their natal river to reproduce, just once. For the five species of Pacific salmon (Chinook, chum, coho, pink, and sockeye), this arduous journey is a race against the clock that ends in a fleeting romance and ultimately death.

The answer to why they die, it turns out, hinges on a problem every animal on Earth has had to solve.

“Every kind of organism has evolved to solve the problem of balancing how much energy to put into surviving to first reproduction and how much energy to put into surviving to reproduce repeatedly,” said Steve Lindley, the director of NOAA’s Fisheries Ecology Division.

“Salmon are one of the extreme cases where they put everything into reproducing just once, and then getting old and dying almost immediately thereafter (a common strategy among insects but much less so for vertebrates).”

The reason for this, Lindley suggested, has to do with the difficult upriver migration salmon make back to their own spawning location. Flipping their bodies in the air and hurling themselves against the downward flowing water is no easy feat and one that is energetically exhausting. Because of this, salmon must fully develop in the ocean and build up fat reserves. Once they enter the river there is little food to eat and they stop investing in the maintenance of their bodies.

“The proximate reasons have to do with DNA switches,” Lindley said. “Essentially many of the activities that operate in immature salmon to allow them to maintain their health, grow and mature are turned off after maturation, and without maintenance they pretty rapidly ‘fall apart’.”

An alternative for these salmon species would be to spend more time in the ocean, accumulating food and energy so they are then able to migrate back after spawning. But this increases their risk of dying before getting the chance to spawn and for Pacific salmon, this is a risk too great.

Volunteers sought to repair trails damaged by American fire

Tahoe National Forest officials have reopened parts of two popular trails damaged in August by the American fire and are seeking volunteers to help rehabilitate the remaining trail segments.

The Western States Trail is open between Michigan Bluff and Deadwood Cemetery, and OHV Trail Loop 6, also known as Forest Service Trail 11E44, is open west of Deadwood Ridge Road.

The entire fire area, including all trails and roads within it, will remain closed for public safety until May 1, said Gwen Ernst-Ulrich, forest spokeswoman.

The fire, northeast of Foresthill in Placer County, burned 27,440 acres within the forest’s American River Ranger District and surrounding properties, including three historic buildings at the Pacific Slab mine.

Eighteen of the 25 miles of the Western States Trail damaged by the fire have been rehabilitated, Ernst-Ulrich said, and efforts are underway to winterize the remaining seven miles to minimize erosion.

Since 1974, the trail has been the site each June of the internationally known Western States 100-Mile Endurance Run from Squaw Valley to Auburn and, in August, the Tevis Cup Endurance Ride.

The remaining damaged seven-mile segment, between Last Chance and Deadwood, is listed on the National Register of Historic Places. It includes two fire-damaged bridges across the northern portion of the middle fork of the American River canyon.

“The (ranger) district is looking at alternate routes for these events if the swinging bridge that crosses the river is not able to be used in time,” Ernst-Ulrich said. “Thousands of other recreationists use this popular trail annually.”
