CalTrout wants old Scott Dam on Eel River removed to help salmon and steelhead

Guy Kovner, THE PRESS DEMOCRAT

A state environmental group is calling for the removal of an old dam on the Eel River, contending it threatens the future of protected salmon and steelhead while acknowledging it is a key part of the North Bay’s water supply.

Scott Dam, a 138-foot concrete dam erected in 1922, is one of five aging dams California Trout asserts are “ripe for removal” to benefit their natural surroundings and communities.

The nearly 50-year-old nonprofit known as CalTrout said in its report, “Top 5 California Dams Out,” the Eel River represents “perhaps the greatest opportunity in California to restore a watershed to its former abundance of wild salmonids.”

Scott Dam, located in Lake County’s portion of the Mendocino National Forest, has been a longstanding target of other groups, including Friends of the Eel River, who want steelhead, coho and chinook salmon to swim freely within the 288 miles of habitat in the Eel watershed blocked by the dam.

The environmentalists see a “unique opportunity” to achieve their goal, as California’s largest utility PG&E, which has owned the dam as part of a small hydropower project since 1930, has filed Chapter 11 bankruptcy and abandoned plans to sell or seek relicensing of the project that diverts 20 billion gallons of water a year from the Eel to the Russian River at Potter Valley.

Eel River interests have considered the diversion a form of theft, while the water is critical to towns and ranches on the upper Russian River from Potter Valley to Healdsburg and part of the water supply for 600,000 residents in Sonoma and Marin counties.

How the future of the Potter Valley Project will play out over the next 18 months to two years is unclear, but it appears likely to result in either decommissioning or relicensing of the project, which includes a small powerhouse and two Eel River dams.

The bottom line is either PG&E or a new owner of the project may face a choice between paying more than $90 million for a fish ladder at Scott Dam or about $70 million to remove it.

Wild and harnessed, Eel River a vital, troubled North Coast watershed 

Guy Kovner, THE PRESS DEMOCRAT

The dispute [over Eel River water] will be aired this summer when the Sonoma County Water Agency releases an environmental report on proposed changes to a decision by state water regulators who 30 years ago established the minimum streamflow requirements on the Russian River. The water agency intends to hold workshops and public hearings on the report.

The roar of water cascading over a 109-year-old concrete dam on the Eel River in Mendocino County was music to Janet Pauli.
“It should be a welcome sound for everybody on the North Coast,” said the longtime Potter Valley rancher, watching the river run down a remote canyon in the Coast Range, bound for the Pacific Ocean far away near Eureka.
Twelve miles the other way, the gates atop another dam had closed a week ago, and the Lake Pillsbury reservoir was filling fast with runoff from early spring rains, offering strong hope of a normal season after four years of drought for the multitude of people who depend on the Eel River for necessities and revelries, including water, wine grapes and stalking wild steelhead trout.
That group includes the 600,000 people in Sonoma and Marin counties who get their drinking water from the Sonoma County Water Agency, ranchers and residents on the upper Russian River, and people along the Eel River as it courses nearly 200 miles through Mendocino and Humboldt counties, passing through nearly untouched wilderness, giant redwood forests, small towns, popular parks and attractions like the Benbow Inn near Garberville before it flattens in the coastal plain approaching the coast.
Most have no idea how these two dams and a mile-long tunnel through a mountain move about 20 billion gallons of water a year from the Eel River into the Russian River, crossing a geographically narrow but politically wide gap and inciting the North Coast’s version of California’s age-old water wars.
“It’s our chapter of western water (conflict),” said David Keller of Petaluma, a leader of the group that has tried for more than two decades to halt the diversion of Eel River water that has gone on for nearly a century. The dams, diversion tunnel and a powerhouse are known as the Potter Valley Project, operated by PG&E.

Feds OK plan to keep more water in Lake Pillsbury reservoir

Glenda Anderson, THE PRESS DEMOCRAT
Federal authorities have granted temporary flow reductions aimed at keeping more water in Lake Pillsbury, a small but crucial reservoir high in the Mendocino National Forest that supplies water to the Eel River, Lake Mendocino, the Russian River and the people, farmers and fish dependent on them. The move is aimed at ensuring healthier river flows into the fall.
The changes, implemented Monday by PG&E, which owns the reservoir, will remain in effect until June 18, providing sufficient time for the Federal Energy Regulatory Commission to collect and review public comments on the changes and make a final determination. A 15-day comment period began Monday. The amount of the flows will vary depending on factors that include how much water is in the lake.
Potter Valley Irrigation District board member Janet Pauli is happy with the decision and optimistic it will remain in place until Dec. 1, as requested. The district is dependent on a water diversion from the Eel River.
“It’s important,” she said of the effort to conserve the water until the next rainy season.
PG&E sought the change largely to maintain at least 10,000 acre feet of water in the reservoir through the fall in order to prevent its banks from sloughing, downstream turbidity and potential blocking of its outlet. There currently is about 38,500 acre-feet of water in the reservoir. An acre-foot is about enough water to fill a football field a foot deep, or supply one household with 893 gallons of water a day for a year.
Environmentalists, water agencies, fisheries officials and farmers hope that holding back water in the reservoir now will mean there will still be water flowing in the fall.

Water-supply worries over remote Lake Pillsbury

Guy Kovner, THE PRESS DEMOCRAT
Water supplies for Sonoma, Mendocino and Marin counties this summer could hinge partly on the dwindling storage in a remote, drought-starved reservoir on the Eel River that serves as a cornerstone to the region’s water system.
Water managers, fisheries biologists, environmentalists and PG&E have their eyes on Lake Pillsbury, a diminishing Lake County reservoir where storage has dropped 30 percent in the past three months, leaving it at less than 55 percent of capacity. Barring a change in water policy, the situation could lead to a string of empty reservoirs by year’s end, officials said Friday.
“We get to a place where we’re threatened with dry lakes,” said Janet Pauli, a Mendocino County grape grower who has long served on a local irrigation district that depends upon the reservoir’s supply.
Lake Pillsbury’s decline most immediately affects about 300 ranchers in Potter Valley, but its repercussions could reach Lake Mendocino near Ukiah, and ripple down the Russian River to eventually touch the 660,000 customers in Sonoma and Marin counties whose water is drawn from the river by the Sonoma County Water Agency.
“This is an unprecedented situation,” said Grant Davis, the agency’s general manager.
It underscores the need, he said, for communities that depend on Russian River water to boost conservation efforts and develop off-river alternatives, such as recycled wastewater.
