Salmon rebound in Sacramento Valley |
|
By Matt Weiser The salmon came back. After four long years of record-low numbers, the fall-run chinook salmon population surged back from the ocean this year, once again filling the Sacramento Valley's rivers on their spawning run. Hatcheries on the American River, the Feather River and Battle Creek – the region's three largest – saw the return of more than double the number of fish in 2010, and five times as many as in 2009. Anglers, wounded by the unprecedented cancellation of fishing seasons in 2008 and 2009, are back on the water. Local salmon is back on dinner menus. Maybe most important of all, the rivers seem to have life again. "There was plenty of fish out there," said Don Herrold, a Rancho Cordova resident who has fished for salmon in the American River for more than 50 years. "It felt great. It's part of our heritage here in Sacramento." This year's local fishing season, which started in July, draws to a close this month. Herrold said he caught 10 salmon this season, mostly near the mouth of the American River. Three weighed over 30 pounds. He smoked the fish himself and gave some to his wife's hairdresser, manicurist and their house cleaner. "I had a very, very good season," Herrold said. "I know the bait shops really benefited. You could tell because you would go in to buy your favorite lure and the walls would be empty." J.D. Richey, a Sacramento fishing guide, had a bounty of clients again as anglers satisfied a pent-up demand for salmon. "It was the best salmon fishing we've seen in 10 years. It was fabulous," said Richey. "It felt like we had vibrant rivers again." But make no mistake, it is still a tenuous existence for Central Valley salmon. Cut off from thousands of miles of their historic habitat by dams, the species now depends largely on hatcheries. Rather than swimming into mountain streams, most of the run now ends up in the hatcheries, built to atone for the dams. There, males and females are killed and cut open, and their eggs and sperm mixed artificially. The resulting young salmon, or fry, are reared in tanks until they reach fingerling size. Most are then hauled in trucks to San Pablo Bay to help them avoid the pollution, predators and water diversion pumps in the Delta. The Pacific Ocean is their home for the next two to four years, when the fish are mysteriously compelled to swim back into fresh water. Ocean's health improves The decline in the salmon population in recent years likely resulted from a combination of drought and poor ocean conditions. This deprived young salmon, first, of freshwater habitat and, second, of food in the ocean once they got there. The three-year drought also cast a spotlight on water management challenges in the Sacramento-San Joaquin Delta, which provides drinking water to 25 million Californians. The state learned it may not have enough water to serve both its people and fish. "The lesson you get from this year is that, when you get a lot of water in the system, the fish really respond," said Peter Moyle, a fisheries biologist at the University of California, Davis, who has studied the region's salmon for decades. "And it wasn't just salmon. Everything responded." Last winter made all the difference. Bountiful rain and snow delivered enough water to fill the state's reservoirs and provide ample flow for fish migration. At the same time, the ocean improved with normal upwelling conditions that brought nutrients up from cold, deep water to charge the food chain. The large number of dolphins and whales in coastal waters provided one of the most spectacular pieces of proof. "The ocean looks better than I've ever seen it," said Larry Collins, a commercial salmon and crab fisherman and president of the San Francisco Crab Boat Owners Association. "I'm thinking next year could be big. We're really hoping." That hope rests on the fact that a large share of the spawning salmon this year were 2-year-old fish. Salmon normally spawn at 3 or 4 years old. The high number of 2-year-olds in the mix usually suggests an even greater number are still in the ocean and will spawn as 3-year-olds the following year. About half the spawning fish at the three large hatcheries were 2-year-olds this year, an unusually large percentage. "It was impressive looking out on the fish ladder at times to see all the fish that were stacked up," said Brett Galyean, deputy manager of the Coleman National Hatchery on Battle Creek. "Hopefully we can keep going on this upward trend for a while and enjoy the ride." Hatcheries' role grows This year's abundance is still a far cry from historical conditions, when the run regularly included hundreds of thousands of salmon. And though there were more fish this year, anglers noticed most were on the small side. The shortages in recent years spurred important research on the salmon population, much of it ongoing. One important realization is that Central Valley salmon have become largely a hatchery-dependent species. The state has begun tagging 25 percent of all hatchery salmon with coded wires. Recovered when the fish return as adults to spawn, the tags provide initial indications that as much as 80 percent of the fall run is composed of hatchery-raised fish. A new emphasis is being placed on creating more wild spawning habitat. Gravel beds are being restored below the dams, and fish ladders are being built so salmon can again access old habitat above the dams. The Nevada Irrigation District, serving Nevada, Placer and Yuba counties, last month completed a new fish ladder at its Lincoln Gauging Station, a small dam on Auburn Ravine. Salmon now have access to an additional mile of spawning habitat there. Similar projects are being considered for larger dams in the region. But because of the cost of large fish ladders, salmon might be trucked around these dams in the years to come. Hatchery and water management practices are also getting close scrutiny in order to boost fish survival. This fall, the U.S. Bureau of Reclamation closed its Delta Cross Channel Gates near Walnut Grove during a crucial part of the spawning run. The goal was to prevent Mokelumne River salmon from getting lost on their run. The gates, built in the 1950s, have historically been left open during the run to provide fresh water for urban and agricultural diversions. At the same time, the East Bay Municipal Utility District, which operates Pardee Reservoir upstream, released water in special pulse flows to help provide salmon with migratory cues. The Mokelumne River Hatchery also began releasing its juvenile salmon at Sherman Island, near the Delta's western edge, rather than in the Central Delta. The goal is to protect the fish from predators during their outward migration. These measures apparently worked. This year, 15,849 adult salmon returned to the Mokelumne hatchery, three times more than last year and far more than the dismal 234 fish that returned in 2008. "It seems to be working quite well," said William Smith, the Mokelumne hatchery manager. "We are definitely rebounding." |

Water districts accuse feds of killing salmon on Stan |
|
Written by Ryan Campbell Finger-pointing has begun in earnest following the destruction of dozens of Chinook salmon spawning grounds in the Stanislaus River this month. Area irrigation districts are claiming that federal water regulators failed to properly manage the flow of water down the Stanislaus River over the past several months, causing about 23 spawning zones to be left high and dry after salmon deposited their eggs. The fish kerfuffle began after the U.S. Bureau of Reclamation, which operates New Melones Reservoir, began releasing more than 2,000 cubic feet of water per second into the Stanislaus River. The flow was well above the seasonal average of 500 cubic feet per second due to unusually high rainfall last year. The greater volume of water drove breeding salmon populations further into spawning channels than usual, according to biologist Doug Demko with the Oakdale-based firm FISHBIO, which conducts studies of several San Joaquin Valley irrigation districts. When the Bureau of Reclamation reduced the flow to more normal levels on Nov. 2, several breeding channels were drained, leaving spawning zones or “redds” to dry out or become stagnant, he said. “Salmon are very particular. They need a lot of flow for their nests,” he said. Demko said the move was essentially a mistake that could have been avoided if the bureau had contacted FISHBIO or one of the three major irrigation districts that draw water from the lower Stanislaus River —the Oakdale and South San Joaquin irrigation districts and the Stockton East Water District. The areas primarily affected are between Knights Ferry and Orange Blossom Bridge. Some of the areas that went dry were restoration sites the government spent hundreds of thousands of dollars to make suitable for salmon redds, Demko said. He said about 23 redds were destroyed outright while another 13 were damaged, amounting to the loss of roughly 10 percent of the entire breeding population of Chinook salmon, which is classified by the federal government as a “species of concern.” He said as many as 200,000 eggs could have been lost due to the flow variations, potentially impacting future salmon runs up the Stanislaus River. “It doesn’t matter if flows are increased now, those eggs are dead,” he said. But higher-than-average water levels left the federal agency no choice but to release “pulse” flows from New Melones Reservoir, according to Louis Moore, spokesman for the U.S. Bureau of Reclamation. “We were making adjustments to make sure safe space was maintained in the reservoir,” he said. “We need to make sure we have enough space in the reservoir to make room for storm systems that might come in.” He said it is not unusual for salmon spawning grounds to be damaged during high-flow years, but that the bureau was able to achieve the“best case scenario for all the demands involved.” New Melones Reservoir now stands at roughly 81 percent capacity with 1.95 million acre-feet of water in storage. “It’s always a balancing act to maintain water storage at the reservoir,” Moore said. Valley water authorities, meanwhile, were calling for more communication with state and federal water policymakers — as well as a position on the Stanislaus Operating Group, which helps decide how much water should flow down the river. “Because we hold the first water rights to the Stanislaus River, we think we deserve the right to sit on that committee,” said Jeff Shields, general manager of the South San Joaquin Irrigation District. He said state and federal water agencies have ignored much of the research and expertise local water agencies have offered. “We should have been releasing a lot more water throughout the year,” said Kevin Kauffman, general manager of the Stockton East Water District. Steve Knell, general manager of the Oakdale Irrigation District, said the bureau should have either maintained higher water levels throughout the salmon nesting season, or kept the water level low. “They ran the river high and encouraged (the salmon) to go into the back channels, and then they cut the water level,” he said. “We ended up with this unfortunate loss of salmon.” He said the Bureau of Reclamation should listen to the concerns of local agencies because they have more expertise in specific river systems. “The irrigation districts know more about the river than the state and federal government, but when it comes to decision time we don’t have a seat at the table,” he said. |
Striped bass are pawns in water games |
|
By Peter Ottesen Since 1879, when striped bass were introduced into the Delta from the East Coast, stripers and Chinook salmon coexisted so well that their numbers expanded into the millions of adult-sized fish. That is until 1999, when excessive water exports to Southern California set the Delta's ecology on its ear and caused severe declines in many species - Delta smelt, sturgeon, steelhead and American shad - in addition to the collapse of stripers and salmon. |
Chinooks take biologists' bait |
|
By Alex Breitler STOCKTON - King salmon have returned to the Calaveras River, swimming through the heart of Stockton for the first time in four years. And on this visit, they're finding the accommodations more to their liking. Just east of Highway 99, crews have finished knocking out one of four major barriers which have often prevented the chinook from completing their voyage from the ocean. Meanwhile, last year's heavy rainfall allowed officials at New Hogan Dam to release a special pulse of water earlier this month. The extra flow - nearly 10 times what would normally be in the river - alerted fish in the Delta that it was time to journey upstream. Journey they did, swimming right under Pershing Avenue and past the University of the Pacific, all the way through urban Stockton. It'll be weeks before experts know how many of the perhaps 3-foot-long fish made the trip. Kari Burr, a senior biologist with the Fishery Foundation of California, said this is the most salmon she's seen on the Calaveras since 2005. "I just want Stockton to know they have chinook in their river," Burr said Wednesday. How many of those fish will successfully spawn is another story. The Calaveras is still a bit of a dead end as fish approach the foothill country. Many salmon are unable to flop over the top of Bellota Weir, east of Linden. That's a problem because the best places to spawn are above the weir. Long-awaited plans to build a permanent $7 million fish ladder there are still on hold. "It's really frustrating," Burr said. "Until that gets fixed, they're not going to get upstream." What's more, extra flows to guide the fish aren't always a guarantee. During the recent drought that water would not have been available, says the Stockton East Water District, which diverts much of the river for farms and drinking water. Regardless, when it comes to the often overlooked Calaveras, you have to celebrate the small victories. "I think everybody's thrilled," said Kevin Kauffman, general manager of the water district. "The pulse flows we're putting down seem to be doing their job in attracting the fish." Stacy Luthy, an assistant professor of biology at Pacific, had never seen a chinook in the Calaveras. She arrived at the university in 2007. Last week Luthy deployed special sonar equipment just west of the university footbridge, and spotted the profile of what appeared to be a large salmon. "It was amazing," Luthy said. She and Burr then headed upstream to Budiselich Dam near Highway 99, where only a few weeks earlier crews finished building a rock ramp to help fish upstream. (In the past, salmon had to climb a steep pitch of about 7 vertical feet - a tall task, even for chinook.) The biologists saw no fish, but it was clear salmon would be able to wriggle up the ramp. So they went farther upstream, to Bellota, where they watched as salmon flopped their way onto the dam's concrete apron in what appeared to be futile attempts to get over the top. Burr said she counted 45 attempts by fish to get over the weir in the span of about one hour. Two temporary fish ladders were placed there, but most of the fish didn't appear to be using them, she said. Donnie Ratcliff, a Lodi-based biologist with the U.S. Fish and Wildlife Service, said there is some chance that the frustrated fish will reproduce even below Bellota. But there might be too many fish competing for a limited amount of quality habitat. Stockton East has committed to improve passage at Bellota as part of a years-overdue habitat conservation plan. The plan has been sitting in the offices of federal wildlife regulators who have been busy with bigger rivers and bigger problems - like the deteriorating Delta. Ratcliff said resolving the problem at Budiselich Dam is, at least, a first step. "You've got to work on whatever you can work on," he said. The extra flows from New Hogan have subsided, but Stockton East plans to release another wave of water around Thanksgiving. That could help additional fall-run chinook as well as steelhead, a threatened species. The Calaveras is not known as a great salmon stream. Historically, it fluctuated based on how much rain fell. When there was water, opportunistic salmon took advantage. But the barriers and the regulation of flows from New Hogan took away some of those opportunities. On Wednesday morning, at the dam restoration site near Highway 99, Ratcliff and John Green, assistant general manager at Stockton East, watched the water as it splashed down the terraced rock ramp, swirled around carefully placed boulders and over large pebbles. What stood out, though, was the sound. "It sounds like a river," Green said. |

Lethal virus from salmon farms seen in wild sockeye |
|
By Peter Fimrite The discovery in British Columbia of an infectious virus that has devastated salmon farms on the East Coast, in Europe and Chile has alarmed conservationists, some of whom blame the aquaculture industry, but fishery scientists say it is too early to panic. The lethal virus, infectious salmon anemia, was detected in two of the 48 wild sockeye salmon tested during a Simon Fraser University study in Rivers Inlet, on the central coast of British Columbia. The implication is that the disease could already be running rampant through the wild population of Pacific salmon, including California chinook and coho. The virus kills fish in as little as 10 days but has no effect on humans. "The concern is that it could spread," said Richard Routledge, a Simon Fraser professor and environmental scientist who found the virus in tissue samples of smolts during an ongoing sockeye study that began in 2002. "Many of the wild salmon populations migrate along the continental shelf in the United States and Canada, and they presumably come in contact with each other." The European strain of the virus, which until now had never been detected in salmon on the Pacific Coast, was confirmed this month by the Atlantic Veterinary College in Prince Edward Island. It was found in the heart tissues of the two sockeye and reported to the Canadian Food Inspection Agency, which is conducting an investigation. The virus has devastated Atlantic salmon populations in Maine, Norway, South America and eastern Canada. No vaccine, no cureThere is no vaccine or cure for the disease, which has always been associated with fish in offshore saltwater pens, where most of the Atlantic salmon sold in the United States comes from. The discovery of the virus among wild migrating sockeye has created a furor, especially considering that the Atlantic salmon being raised in exposed pens in British Columbia fjords and inlets are the most likely vectors. Millions of Atlantic salmon eggs have been imported to the province over the last 25 years, primarily from Iceland and Scandinavia, officials said. "The problem is you are raising salmon in pens and the sockeye are migrating past those pens, so it's very easy for them to pick up diseases from those pens," said Peter Moyle, a professor of fish biology at UC Davis. "We know it can happen. Salmon can pick up viruses in the water." Fishery biologists in British Columbia warned against jumping to conclusions. Jim Winton, the chief of the research section for the U.S. Geological Survey's Western Fisheries Research Center in Seattle, said some 4,000 penned Atlantic salmon have been tested over the past three or four years and no trace of the virus has been found. "The question is, how did the virus occur in wild fish when the disease was not present in the salmon farms?" Winton said. There are other possibilities, Winton said. He said some species of cod and other fish migrate across the Arctic Ocean and might have carried infectious salmon anemia to the Pacific. Fish and their diseases also frequently get transported in the ballast of ships, he said. Previous tests have shown that some of the five species of Pacific salmon are less susceptible than Atlantic salmon to the disease. Here all along?"It is very possible that it was always here but just was never detected," said Mark Strom, a research scientist and microbiology program manager for the National Marine Fishery Service's Northwest Fisheries Science Center in Seattle. Nobody really knows at this point whether the virus has spread, but Routledge is concerned because he had previously heard reports about fish showing symptoms of the disease. He said he took the samples after he and his students had a difficult time catching sockeye, an indication to him that the local fish population was in decline. There are a lot of other reasons to be concerned, Moyle said, especially considering recent history. He said farmed Atlantic salmon have often escaped from their pens, sometimes through rips in the nets. Thousands were released during a storm in Norway several years ago, he said. Atlantic salmon are now regularly found in streams and the ocean in British Columbia, he said. The mixing of wild and farm-raised fish is a worry because studies have documented wild fish with sea lice and other infections that were spread by farmed fish. Researchers have also documented fertility problems and less-robust offspring after wild fish have mated with hatchery fish, even after a generation in the wild. Virus can mutateThe experts agree that the presence of the virus is bad news even if there is some immunity among Pacific salmon. The pathogen is a member of the orthomyxo family, which includes influenza. And, like the flu, infectious salmon anemia can mutate. "This virus can mutate from a benign form to a particularly virulent one, and it has done this in the relatively recent past," Routledge said. "The implications could be very serious." California does not practice fish farming the same way as British Columbia - the state's hatcheries raise fish for release into the wild - and Moyle said the California fishery does not appear to be in immediate danger. The virus could nonetheless be a death knell for the West Coast fishing industry, he said, were it to find its way into the state's signature chinook stock. "Anytime you have a new disease that occurs, it could be devastating," Moyle said. |
Tribes Join Together to Restore Eel River |
|
By Dan Bacher Native American Indian tribes from throughout Northern California are banding together with Friends of the Eel River to take “spiritual, scientific, and legal” action to save the waterway and the fish that swim in it. Since 2009, multi-tribe ceremonies have taken place in different parts of the nearly 3,600-square mile Eel River watershed; the most recent, in which the Wiyot Tribe, Friends of the Eel River were joined by members of the Bear River, Cahto, Grindstone, Sherwood Rancheria, Round Valley, Pomo, Hoopa, Yurok, and Karuk Tribes, occurred on September 10 and focused on returning the Eel River and the fisheries it supports to a healthy, sustainable state. “Rivers need water to survive,” said Nadananda, Executive Director of the Friends of the Eel River. “The cost of diverting so much water out of the Eel River is simply too high. Salmon and steelhead are on the brink of extinction here. While increases in water flows over the past five years have made it possible for Chinook salmon populations to begin to make a comeback, significantly more water will need to be returned to the river if we are going to save these fish.” In 2004, dam owner Pacific Gas & Electric (PG&E) increased flows on the Eel River from 5 cubic feet/second to 20-25 cubic feet/second under the orders of the Federal Energy Regulatory Commission. The 2010 fall run of chinook salmon on the Eel River was the largest recorded in 77 years, with more than 2,300 adult fish migrating upriver to spawn. Last year’s salmon run also benefitted from an unusually heavy rain season. The September event marks the first time that so many different tribes came together in call for healing on the river. Salmon are a sacred fish and traditional source of food for the Round Valley Tribes and other Native American Indians who were once the only human inhabitants of this remote watershed. Members from several of the tribes performed tribal prayer dances at the mouth of the river on the Wiyot’s Table Bluff Reservation. ”This day, Wiyot Day, is a way to show respect for our elders and for where we come from—for many of us, the Eel River is a big part of that,” Wiyot Tribal Chairman Ted Hernandez told the Eureka Times-Standard. “The tribes native to this area once thrived on the abundant salmon runs on the Eel River,” said former Round Valley Tribal Council member and current Friends of the Eel River board member Ernie Merrifield. “We must rely on all of our resources—spiritual, scientific, and legal—to restore this river and these fisheries to health. If we work together, we may have a chance to reverse the damage caused by a century of water deprivation.” Last year’s record salmon run, the largest number of fish counted at the Van Arsdale Fisheries Station on the Eel River below Cape Horn Dam since the Department of Fish and Game (DFG) began keeping records, arrived just a few months after members of the Round Valley Indian Tribes of Covelo conducted dances and ceremonies to bring back the salmon. In July of 2010, the Feather Dancers of the Tribes joined Friends of the Eel River at a swimming hole in the Hearst area, a few miles downstream of the PG&E Potter Valley diversion (PVP) to the Russian River. “Water and salmon hold sacred value among the Tribes of the Round Valley, and both have been bankrupted,” said Merrifield. “Like a person, if you block the free flow of blood in your veins you will die, just as PG&E’s dams are killing the Eel River.” FOER will continue its efforts to improve river conditions in the coming year. The group will present information to the State Water Resources Board next year as Sonoma County renegotiates flows between the Russian and Eel Rivers. According to the National Oceanic and Atmospheric Agency, the current flow regimes on both rivers are damaging endangered salmon and steelhead habitat due to insufficient water in the Eel and too much water in the Russian. FOER is also a party to an ongoing lawsuit aimed at preventing an environmentally damaging quarry and freight railroad from reopening within the sensitive Eel River watershed. |
Fish habitat project begins in Dry Creek watershed |
|
By Clark Mason Construction will begin next week on a project designed to restore passage of endangered fish on a tributary of Dry Creek, northwest of Healdsburg. Crane Creek has habitat for spawning and rearing coho salmon and steelhead, but access to the stream has been limited by a bedrock waterfall that makes it difficult for the fish to swim upstream. By creating a series of weirs and pools, more than a mile of critical habitat will be opened up for the fish to spawn and spend the first years of their lives. Construction of the $60,000 project is estimated to take two weeks. The project is a partnership between the Sonoma County Water Agency and the Sotoyome Resource Conservation District, as well as local landowners. It's “a great example of family farmers and local government coming together to help these endangered fish,” stated North County Supervisor Mike McGuire, whose district encompasses the area. He singled out landowners Doug Lipton, Cindy Daniel and Ronald and Pamela Wollmer for collaborating on the restoration effort. |
Coho release highlights 10-year Willow Creek restoration |
|
By Derek Moore Wearing waders and what looked like small kegs strapped to their backs, a team of government biologists slogged through Willow Creek near Jenner Tuesday searching for good places to let their precious cargos go. Dipping nets into the aerated containers, the biologists released juvenile Coho salmon into the creek a couple at a time, allowing the silvery fish to dart away beneath a canopy of Redwood trees. Tuesday's release of 11,000 Coho into Willow Creek marked a new phase in what has been a major and time-consuming effort to restore the endangered fish to the waterway, which is the largest of the tributaries flowing into the Jenner estuary. A decade of planning that has involved numerous government agencies and non-profit organizations has so far gone into the restoration effort, which also has included spending more than $1 million to upgrade a bridge that was considered a main barrier to salmon thriving in the creek. Observing Tuesday's fish release, Michele Luna, executive director of Stewards of the Coast and Redwoods, reminisced about the first planning meeting 10 years ago. “We got a bunch of people in a room and said, ‘What do we need to do in order to do some restoration work on Willow Creek?'” she said. The answer, as it turned out, was a lot. Willow Creek, which flows nearly nine miles from Coleman Valley to the Jenner estuary, was once prime habitat for salmon. But run-off from logging and agricultural activities, coupled with the discontinuation of dredging efforts that were aimed at preventing roadway flooding, had turned the once pristine waterway into a clogged and meandering mess. The watershed is mostly within Sonoma Coast State Park. It also flows in an area of privately-held ranches and land owned by the Mendocino Redwood Company. A network of culverts that had been accumulating sediment after state parks purchased the property in 1987 and discontinued dredging were identified as significant impediments to Coho salmon being able to travel up and down the creek. The stewards group proposed replacing the culverts with a 43-foot bridge that is nearing completion and that will re-establish connectivity through 1,000 feet of wetlands. The work, totaling more than $1 million, is being paid for with a combination of government grants. Several of the agencies involved in the project had representatives on hand Tuesday, including from the U.S. Army Corps of Engineers, the National Oceanic and Atmospheric Administration, the California Department of Fish and Game, state parks and the Sonoma County Water Agency. Joe Pecharich with NOAA said the federal agency is making the Willow Creek restoration effort a high priority — contributing $400,000 through the agency's Open Rivers Initiative — because it potentially buys “seven miles of additional habitat for endangered Coho salmon.” Fish and Game put in $352,000 and Trout Unlimited secured $100,000 from the county water agency. “It's really an exciting multi-agency collaboration that has been sustained for a number of years,” said David Manning, the supervisory biologist for the water agency. The fish released Tuesday were raised at the Warm Springs National Hatchery, which is leading an effort to restore salmon populations in waterways across Northern California, including the release of 170,000 fish into 22 Sonoma County streams this fall. As many as 50 percent of the salmon fingerlings released into Willow Creek Tuesday are expected to survive, according to Ben White, a fisheries biologist for the Corps. He said all of the fish have tiny wire tags implanted in their snouts, and that a smaller number carry transponders for more advanced tracking. White said if all goes well, the fish will venture downstream in the spring and spend the next two years maturing in the ocean, before returning to the creek to spawn. Bill Bambrick, president of the Stewards' board of directors, said the water tests that he and other volunteers have been conducting at Willow Creek since 2003 have revealed ideal conditions for Coho, including an average water temperature between 50 and 55 degrees. “If they could get up here, they'd love it,” Bambrick said. |
Salmon-Killing Virus Seen for First Time in the Wild on the Pacific Coast |
| By Cornelia Dean and Rachel Nuwer A lethal and highly contagious marine virus has been detected for the first time in wild salmon in the Pacific Northwest, researchers in British Columbia said on Monday, stirring concern that it could spread there, as it has in Chile, Scotland and elsewhere. Farms hit by the virus, infectious salmon anemia, have lost 70 percent or more of their fish in recent decades. But until now, the virus, which does not affect humans, had never been confirmed on the West Coast of North America. |
Workers rush to restore Roseville streambed before salmon arrive |
By Ed Fletcher Delayed by vandals and two early fall storms, a crew in Placer County is racing to finish a stream-restoration project before the salmon they're trying to protect begin their annual migration. The timetable is critical, with the start of the fall salmon run only weeks off. The nonprofit Dry Creek Conservancy, working with the city of Roseville, is using a $150,000 grant from the state Department of Water Resources to remove physical barriers and improve the fish habitat at a key location along Secret Ravine Creek in Roseville. The stream has been identified by environmentalists as a prime spawning area for fall-run chinook salmon and steelhead trout. Environmentalists and some government agencies have been working to undo some of the negative impacts of development. Backers of the Secret Ravine project said this one is noteworthy in that it attacks the issue in an urban waterway a short distance from a movie multiplex, strip mall and water park. "I don't think there has been a project like this in the Sacramento metro area," said Greg Bates, executive director of the Dry Creek Conservancy. "It's pretty exciting." The most visible change was the removal of a weathered old bridge, but Bates said the most significant obstacle to fish migration was a section of concrete-covered, unused utility pipes under the bridge. During low flows, the width of the concrete encasement was too much for the fish to jump over, Bates said. Last week, with the bridge gone, a backhoe operator placed large rocks into a dry fork of the creek. Elsewhere, Bates and Delyn Ellison-Lloyd, the city's point person on the project, discussed vegetation issues – specifically whether a grove of willow trees will need to be removed. Meanwhile, the rest of the team prepared to inflate a temporary dam on the active fork of the creek. Once the dam is in place, crews will place large boulders and tree stumps with root balls intact to contour the waterway and provide habitat. Troubles with the temporary dam disrupted the project's timetable, Ellison-Lloyd said. The dam uses two water-filled bladders, filled by a pump, to block the stream flow. The stream flow is then diverted through a pair of 24-inch-diameter plastic pipes and returned to the channel downstream. With the dam in place, crews can work on the streambed below it without sending loose dirt and sediment downstream, which is bad for the fish and other aquatic life. Vagrants camping in the area are believed to be responsible for knocking the pump and a generator out of commission, causing the dam to deflate and be moved aside. Another setback came when recent storms caused the creek to surge. "It didn't seem like that much rain, but the dam was dislodged again," Ellison-Lloyd said. The work originally was expected to be completed last week. The city and conservancy have asked appropriate agencies for an extension allowing them to keep working on the stream until the end of the month, but Bates and Ellison-Lloyd said they hope to get done before that. "What we are trying to do is get out before the salmon season starts," Ellison-Lloyd said. |

By Cathy Locke The California Department of Forestry and Fire Protection is encouraging the public to buy and burn local firewood. Cal Fire and the California Firewood Task Force have launched a campaign to inform campers, wood cutters, arborists and the public about the risks of long-distance movement of firewood. Firewood can carry insects and pathogens that might not be visible, making it impossible to know whether an invasive pest is being transported when firewood is moved, the agency reported. Once an invasive species is established in a new area, it can do considerable damage environmentally and economically because trees in the area have no natural defense to fight off the pest attack, according Don Owen, chairman of the California Firewood Task Force. Buying and burning wood locally is a simple way to minimize the chances of spreading invasive species, he said. The campaign includes surveying campers about their knowledge of invasive species and firewood areas affected by the goldspotted oak borer, an invasive beetle in San Diego County that was likely brought into the state on firewood. Campaign participants also are distributing posters to campgrounds and parks for display in public locations, mailing information to industry professionals, and offering educational Frisbees and playing cards to campers.

Conservation nonprofits squeezed as economy shrinks budgets |
|
By Matt Weiser Nonprofit conservation groups have preserved tens of thousands of acres of land in California – wild places where both hikers and animals roam. Now, some of them say the economic slump could force them to scale back. Others say lean budgets make it harder for them to scrutinize land use proposals for environmental effects – a key role such groups play in the state's push-pull development process. Most groups don't like to talk about their financial difficulties, but one, the American River Conservancy, recently took the unusual step of going public. In an email to members and supporters, the group confessed that "times are hard" and it needs to raise $250,000 by year-end or it will be forced to cut programs in 2012. "What is happening to our organization is happening to a lot of organizations. We're just being honest about it," said Alan Ehrgott, the conservancy's executive director. A major factor is the squeeze on government programs that provide money for land acquisition and education. In addition, private foundations that give grants to environmental groups have seen their endowments shrink substantially as the stock market has struggled. "Every group really has got to focus on what they do well, what their core priorities are," said Tim Little, executive director of the Oakland-based Rose Foundation, which donates to environmental groups and is also helping coach them through tough times. Like a number of other land groups operating in the Sacramento region, the American River Conservancy has worked on setting aside land for both recreation and wildlife habitat. The conservancy has helped preserve 12,000 acres in the American River watershed, particularly along the south fork in the Coloma area. Among these projects was the acquisition last year of Gold Hill Ranch, site of the Wakamatsu Colony, the first Japanese settlement in North America. It also has built more than 27 miles of public recreation trails, including the new South Fork American River Trail, which opened last year between Salmon Falls Road and Highway 49. Lately, though, the group has been retrenching. It slashed its staff costs 27 percent – largely through voluntary actions by its 13 employees – and has tripled the number of grant applications it has in circulation. If it can't raise $250,000, Ehrgott said, the conservancy may have to cut education programs that teach schoolchildren about the area's history and that take low-income kids into the wilderness to work on land management projects and learn about nature. These programs have always been subsidized by grants to make them accessible to low-income participants. Ehrgott said the conservancy could continue the programs by charging participants the full cost, but that would change the experience. "If we charge the full amount, we could probably do fewer trips, (mostly) with kids from wealthier families. But we think that's not socially responsible," he said. "We think everyone needs to learn about the outdoors and natural resource science." A number of nonprofit groups told The Bee their paid membership ranks have remained surprisingly stable. But membership dues typically provide less than half of a conservation group's revenue. Grants provide the rest. In the case of the California Native Plant Society, a statewide group based in Sacramento, memberships provide 40 percent of revenue, said executive director Tara Hansen. "In terms of fundraising, it's definitely difficult," she said. "We have been working really hard to apply for grants and have not done too well this year." Hansen declined to discuss any cost-cutting moves her group is considering. A big task lately, she said, is scrutinizing renewable energy projects – solar, wind and geothermal – proposed throughout the state, especially in desert regions. The group does not oppose renewable energy, Hansen said, but wants to ensure that such projects are planned and built in a way that protects sensitive plants and habitats. It is an example of the complex work, Hansen said, that the average citizen does not have time or expertise to do themselves. "There are impacts on native vegetation all over the state, and we can't cover it all," she said. "We have to prioritize, and sometimes we have to say, 'No, we can't get involved in that.' We just simply don't have the resources." Another watchdog feeling the financial strain is Friends of the River, a statewide organization based in Sacramento. It has long played a prominent role in monitoring state water management policy to protect rivers for recreation and habitat. With just six employees, it currently operates without an executive director as a cost-saving move. "Our budget is down considerably," said Ronald Stork, senior policy advocate with the group and one of the state's leading nongovernmental experts on water management and flood-control policy. "We're thin and we are struggling, but we're hanging in there." The Rose Foundation last week hosted an event to help small nonprofits with their grantmaking pitches. Tim Little acknowledged that a "doom-and-gloom" feeling is taking hold at many nonprofits. But he said there is reason for optimism. "Foundation endowments got whacked, there's no question about it. Donations are down for everybody," said Little, a veteran of several environmental groups. "But there's still a lot of money out there that folks can get. The challenge for every group, more than ever, is to be well organized." |
Vandals set loose 40,000 baby salmon from rearing pens in Tiburon |
|
By Mark Prado Some 40,000 juvenile chinook salmon were set loose into the bay from Tiburon when vandals cut lines supporting the pens in which they were held. The action shortchanges a planned year-end celebration for high school students who raised the fish from eggs and had planned to see them off at the end of the month as part of the Tiburon Salmon Institute's annual program. "It was unreal to hear about it," said Dan Hubacker, the teacher who heads the salmon program at Casa Grande High School in Petaluma, where the fish were reared. "The kids put a lot of energy into the program. Now I have to break the news that their fish are gone. I spoke to the student leader of the program and he was irate." The institute partners with the Tyee Club on the project, which for the past 60-plus years has raised salmon to improve the species' population and provide education and fishing opportunities. The pens have been in Tiburon since 1973 and are tethered to the dock of San Francisco State University's Romberg Tiburon Center near Paradise Beach Park. The pens are 16 by 25 feet and weigh roughly two tons. They have nets that hang down about 8 feet. Sometime between 10:30 a.m. Monday and 9 a.m. Tuesday the thick plastic lines that hold up two of the pens were cut, causing them to sag into the water, allowing the fish to swim out, said Brooke Halsey, executive director of the Tiburon Salmon Institute. Halsey said the nets are repairable and that he will now seek donations to install security cameras at the dock. Deputies from the Marin County Sheriff's Office told Halsey that someone may have released the fish as bait, so that larger fish would be lured to the area and be more easily caught. Halsey said that the young fish are vulnerable. He said that one or more people "came along with essentially what are wire cutters to do this. It was purposeful. Someone knew what they were doing." One of the pens was not touched, and about 20,000 fish remain, but they were not the salmon raised by students, Halsey said. The Casa Grande students work with the fish from November through June. The fish are raised from eggs and eventually transferred to the underwater pens in Tiburon. There, they are fed four times daily by a cadre of volunteers who come from all over the Bay Area, including in summer by Marin children who help tend to the fish with donated pumps, tanks and filters. By the first week of October, the fry have grown threefold, up to 10 inches long, and are released to make their journey through the Golden Gate to open sea. While the fish would have been released anyway at the end of the month at Blackie's Pasture in Tiburon, the vandalism robbed students of the opportunity to finish what they started. "Releasing the fish is the end of the rainbow for us," Halsey said. "That's the heart-wrenching part of this." |
Some water in Delta to be diverted to help salmon |
|
Central Valley Business Times The federal Bureau of Reclamation is closing the Sacramento-San Joaquin Delta’s Cross Channel Gates for ten days beginning Tuesday Oct. 4 during the peak migration for returning adult salmon to the Delta. The gate closing is expected to help king salmon migrate to the Mokelumne River Hatchery. “What this means is we’ll likely see tens of thousands of additional salmon in our coastal waters three years from now because of this action,” says Golden Gate Salmon Association Director Dick Pool. “The Bureau of Reclamation is allowing more natural flows through the Delta for this ten day period which will greatly help adult salmon find their way home to reproduce.” The association says the Cross Channel Gates reroute Sacramento River water to the south Delta, which throws Mokelumne River salmon off their historic migration track. Because of this, there has been only limited successful salmon production from the Mokelumne in recent years, the association says. Last year, closing the Cross Channel Gates for two days resulted in a large number of salmon successfully finding their way to the Mokelumne, it says. Federal water managers purposely force cleaner Sacramento River water off its natural course and into the south Delta at this time of year to dilute polluted San Joaquin River water flowing into the Delta, the association says. The proposal to allow a more natural flow pattern in the Delta was put forth earlier this year by East Bay Municipal Utility District (EBMUD), which owns the hatchery and the Pardee Reservoir on the upper part of the Mokelumne River. The proposal was also supported by California Fish and Game, the U.S. Fish and Wildlife Service and the National Marine Fisheries Service. Last year EBMUD offered to release some of its water to dilute the polluted agricultural runoff in the San Joaquin River. “Salmon fishermen and industries that rely on salmon have something to be very thankful for,” says GGSA president Victor Gonella. “We’ve got a long way to go to restore our rivers, the Delta and our salmon fishery to more natural conditions and abundant levels but this is a big step in the right direction.” The Mokelumne River salmon hatchery, operated by the California Fish and Game Department, is the most modern hatchery in the state. It was built to mitigate for the loss of natural salmon spawning runs of the river. The hatchery trucks its juvenile salmon from the hatchery to a release site near Antioch, safely beyond the point where they would be sucked into Delta pumps near Tracy. When the Mokelumne River is functioning more naturally, without large volumes of Sacramento River water artificially routed across its Delta, 2,000 to 4,000 salmon naturally spawn in the river. In 2005, the last such good year, 10,400 salmon spawned naturally in the Mokelumne River, the association says. |
Another View: Klamath pact doesn't protect the river fishery |
|
By John DeVoe John DeVoe, an attorney and executive director of WaterWatch of Oregon, is responding to the Sept. 25 Viewpoints article "Klamath restoration plan deserves congressional support" which stated: "The agreements would balance water use in the basin in a manner that gives agriculture greater water security while enhancing flows in the river at critical times of year for salmon." While WaterWatch of Oregon supports Klamath River dam removal and has spent decades working toward a sustainable future for the Klamath Basin, we have joined several Oregon and California conservation groups and at least one Native American tribe in opposing the Klamath Basin Restoration Agreement as unscientific, unsustainable and fiscally irresponsible. We believe the Klamath's natural resources and communities deserve better. Proponents of the agreement frequently spout platitudes about the deal but ignore its critical shortcomings when claiming it will resolve the Klamath's fundamental problem – competition over water. Because the deal fails to balance the water budget in the basin, it guarantees the conflict will continue. Though it promises specific water deliveries for irrigation, the agreement fails to guarantee any minimum flows for fish and fails to permanently reduce irrigation to a level that will produce stream flows consistent with the best available science, tribal trust responsibility and Endangered Species Act requirements. The agreement fails to meet the lowest ecological standards. The deal's irrigation water guarantees would regularly cause stream flows to drop below minimum ecological base flows needed for fish survival. Projections indicate high-risk stream flows throughout August for 48 percent of future years, throughout September for 25 percent of years, throughout October and November for at least 98 percent of all future years. Overall, stream flows are projected to drop to dangerous and potentially lethal levels an average of four months each year. To address this shortcoming, supporters propose a vague drought plan echoing previous Klamath water banks. Judging from history, leasing water to bring flows above the ecological danger zone would cost an average of $5 million a year or $250 million over the deal's time span – an extraordinary price to maintain fish conditions at barest survival levels. Flows sufficient for actual salmon recovery would cost more. Moreover, the U.S. Geological Survey found previous Klamath water banking to be unsustainably reliant on groundwater pumping. Because Klamath groundwater and surface water are connected, over time, pumping groundwater to maintain stream flows robs Peter to pay Paul. Fifty years of water banking is neither fiscally nor environmentally sustainable. Adequate stream flows to meet long-term recovery needs for Klamath salmon and other fish will require reduced water use and better water management. Congress must include concrete, science-based stream flow assurances in emerging federal legislation. Only then will we have a chance of achieving peace on the river and a sustainable, vibrant future for region's communities. |
