New momentum in decades-long quest to upgrade Lake Mendocino’s Coyote Valley Dam

Austin Murphy, PRESS DEMOCRAT

With $500,000 secured by Rep. Huffman, officials have launched a study that could result in raising the level of the 67-year-old earthen dam impounding Lake Mendocino.

Striding along the southern edge of Lake Mendocino last week, Rep. Jared Huffman spotted a bald eagle soaring 150 feet above, a fish in its talons.

An avid angler himself, Huffman then pointed to a nearby stand of partly submerged trees — prime bass habitat, he noted.

If he had a rod, said Huffman, the ranking member of the House Committee on Natural Resources, “I would be casting right into that.”

But the congressman, along with a group of local officials, tribal leaders, and members of the U.S. Army Corps of Engineers, had work to do.

The group had gathered last Friday to sign an agreement geared to deliver significant future upgrades to the 67-year-old Coyote Valley Dam, which impounds Lake Mendocino, a reservoir providing flood control for nearby Ukiah, and other communities.

Op-Ed: A seismic threat to Scott Dam

Bob Schneider & Chad Roberts, PRESS DEMOCRAT

The earthquake risk at Scott Dam may be a key factor in PG&E’s decision to abandon the Potter Valley Project.

PG&E is surrendering its license for the Potter Valley Project, two dams that divert water from the Eel River to the Russian River while generating hydropower. PG&E identifies this as a business decision, because of the project’s failure to produce revenues that offset operating costs, even though the utility’s customers pay higher rates than just about everywhere else in the United States.

In our opinion, PG&E has determined to rid itself of the Potter Valley Project for a different kind of economic consideration, after determining that the Scott Dam represents an economic liability that the company cannot afford.

A key factor is the increased understanding of seismic hazards represented by the Bartlett Springs Fault Zone, which runs through Lake Pillsbury approximately 5,000 feet east of Scott Dam.

As part of the relicensing process, the Federal Energy Regulatory Commission held an auction for potential alternative licensees for the Potter Valley Project. No one made an offer, probably for the same reason PG&E doesn’t want the dams anymore: no potential owner wanted responsibility for the risk posed by the Bartlett Springs Fault.

Historic pact reached on future Eel River water flows into Russian River

Mary Callahan, PRESS DEMOCRAT

  • A historic agreement has been reached to manage water flow from the Eel River to the Russian River.
  • The deal establishes limits on diversions, focusing on fish protection.
  • Water rights are transferred to the Round Valley Tribes, supporting river restoration efforts.

Officials from three counties and the Round Valley Indian Tribes have reached a historic agreement that paves the way for continued diversions from the Eel River to bolster flows in the Russian River.

The agreement represents a critical development for anyone whose water comes from the Russian River.

The complex accord resulted from years of negotiations to preserve supplemental flows in the Russian River, the water lifeline for residents, ranchers and wildlife in Sonoma and Mendocino counties. The agreement also supports the restoration and fish recovery in the Eel River, which was crucial to securing support from environmental interests, tribes and Humboldt County residents.

It is, at last, the “two-basin solution” envisioned by regional stakeholders in 2019 and even earlier, when Pacific Gas & Electric first raised questions about whether to continue operating the small, aging hydroelectric plant in Potter Valley through which Eel River flows have been redirected.

The utility is now on track to decommission the plant, tear down Scott Dam, which impounds Lake Pillsbury in Lake County, and Cape Horn Dam 12 miles downstream, where Eel River water has long been diverted.

Rep. Jared Huffman secures $15 million for Eel River Dam removal and Russian River diversion plan

UKIAH DAILY JOURNAL

Rep. Jared Huffman, D-San Rafael, recently announced that the U.S. Bureau of Reclamation has awarded Round Valley Indian Tribes and the Sonoma County Water Agency $15 million toward implementing the Two-Basin Solution for water diversions from the Eel River to the Russian River.

In a press release, Huffman explains that “the funds through the Inflation Reduction Act will fund a major Eel River estuary project supported by the tribes, and put a down payment on construction of a new wintertime diversion to the Russian River following the removal of two salmon-blocking dams on the Eel.”

“This funding shows what can be accomplished thanks to the strong partnerships in the Eel and Russian river basins. We’ve now reached a significant milestone in restoring salmon and other aquatic life in the Eel River while protecting a key water supply for communities in Mendocino, Sonoma, and Marin counties,” Huffman is quoted as saying in the release.

Explaining that “the Pacific Gas and Electric Co. plans to remove Scott and Van Arsdale dams that no longer produce electricity but prevent salmon from reaching 200 miles of spawning habitat, Huffman also notes that “Round Valley Indians Tribes and Sonoma Water worked together on the application and are also working with Mendocino Inland Water and Power Commission on a plan that will benefit both basins.”

Op-Ed: Diversion won’t guarantee a healthy Russian River

Don McEnhill and Ed Burdett, PRESS DEMOCRAT

When PG&E announced that it would remove Scott and Cape Horn dams on the Eel River as part of the Potter Valley hydroelectric project decommissioning, it put a continuing water diversion to the Russian River in question.

A Press Democrat editorial praised Eel and Russian River stakeholders coming together to endorse the possibility of a new fish friendly diversion from the Eel River (“Progress toward water security,” March 27), and we at Russian Riverkeeper concur. However, a continued diversion from the Eel River is not a solution in and of itself when it comes to ensuring long-term water reliability in the upper Russian River watershed. A continued diversion will not solve all the region’s water issues.

Russian Riverkeeper, a Healdsburg-based nonprofit organization founded in 1993 to ensure that river water is drinkable, swimmable, fishable and equitably shared, is supportive of the effort to create a wintertime diversion that allows salmon and Pacific lamprey in the Eel River maximum recovery potential, while still making surplus flows available to the Russian.

PG&E formalizes plan to take down dams on Eel River

Mary Callahan, PRESS DEMOCRAT

In a landmark moment, Pacific Gas & Electric Co. formalized its plans to tear down two more-than-century-old dams on the Eel River — removing the barrier that forms Lake Pillsbury, freeing the waters of the river and restoring the lake footprint to a more natural state.

The moves are part of a 94-page draft surrender application submitted to federal regulators and made public Friday as part of the utility’s plan to decommission its Potter Valley powerhouse and all the infrastructure that comes with it — including Scott and Cape Horn dams, sited slightly downstream.

PG&E has said work deconstructing the dams could begin as early 2028, depending on regulatory approval and environmental review of the plan.

Scott Dam, built in 1921, would come down first, either in phases or all in one season.

The plan fulfills long-held dreams of conservationists and fishery groups to see the cold, clear headwaters of the Eel River, part of the Mendocino National Forest, reopened to migrating fish and to restore natural river flows in hopes of reversing the decline of native fish stocks.

Sonoma, Mendocino county water managers propose pathway for continued Eel River diversions

Mary Callahan, PRESS DEMOCRAT

Water managers in Sonoma and Mendocino counties seek to preserve water transfer infrastructure as part of PG&E license surrender for Potter Valley power plant.

Water managers in Sonoma and Mendocino counties have submitted a conceptual proposal to PG&E to buy and maintain portions of the utility’s defunct Potter Valley power plant to enable future water transfers.

The move would be a critical step toward preserving seasonal diversions of Eel River water to supplement supplies in Lake Mendocino and the Russian River.

Working with the Mendocino County Inland Water and Power Commission and the Round Valley Indian Tribes, the Sonoma County Water Agency is seeking to preserve elements of the power plant through which water is channeled from the Eel River to the East Fork Russian River. No electricity would be generated as a part of the plan.

Pacific Gas & Electric has planned to surrender its license for the 1908 plant with the intent of decommissioning it. Without a proposal to save it, the diversion infrastructure would eventually be removed, leaving upper Russian River communities and agriculture users without sufficient water.

Op-Ed: Eel River dam debate echoes nationally

Cameron Nielson & Sarah Bardeen, THE PRESS DEMOCRAT

On paper, California’s Eel River is a prime candidate for restoration.

It’s a remote river that runs through rugged, lightly populated terrain in Northern California. As with many rivers in the region, a combination of logging, overfishing and dams decimated its once-plentiful salmon and steelhead runs. The introduction of a native predator, the pikeminnow, only made things worse.

But some of that could be put to rights: two aging dams in the Eel’s upper reaches are reaching the end of their life span — and one has been declared seismically unsafe. PG&E, which owns the dams, has chosen not to renew their licenses, setting the stage for removal if no new owner steps forward.

Eel River residents overwhelmingly support dam removal, the tribes are adamantly in favor, and a constellation of NGOs is pushing hard for it. If those dams come down, 150 square miles of cold-water habitat will open up to struggling populations of steelhead and salmon, offering needed refuge from the warming climate.

So why is it so hard to get done?

Part of the answer lies in the dam’s history. Part lies in the challenges of coping with a surfeit of aging infrastructure. And part lies in the complexities of who exactly constitutes the river’s community. Finding a solution has implications not just for the state but for the nation.

PG&E plans to remove both Potter Valley Project Dams—Mendo, Humboldt, Lake and Sonoma Fight

Sarah Reith, REDHEADED BLACKBELT

A planning group for the Russian River Water Forum, which is preparing for life after PG&E decommissions the Potter Valley Project, met for the first time yesterday in Ukiah. PG&E said in a town hall last month that its version of decommissioning means removing both dams. That’s unless an entity that is capable of running them steps forward before it submits a draft of the decommissioning plan to the Federal Energy Regulatory Commission, or FERC.

Tony Gigliotti, PG&E’s senior licensing project manager, laid out the timeline at a town hall about Scott Dam and Lake Pillsbury on April 27th.

“When we say decommissioning in this case, both dams will be removed as part of that, unless somebody comes forward with a proposal that PG&E looks at and accepts,” he said. “We need to ensure they can operate the dams after we give up ownership. In terms of timelines for the surrender application, there will be an initial draft November, 2023. A second draft, also available for public review, May 2024, and then the final application will be filed with FERC in January, 2025.”

Janet Walther, PG&E’s senior manager of hydro licensing, qualified that timeline a little.

“When PG&E submits our final surrender application to FERC, that would be the point of no return,” in terms of decommissioning, she said. “And really, the draft. We are looking to know, sooner than later, if there’s an entity interested in taking over the dam because that will change our surrender application and what we put in that surrender application. So I think we are looking and would like to see some initial proposals later this year, if there is interest. And we are talking with folks, as we have been since 2016, about potential interest in future ownership of Scott, and/or Cape Horn Dam.”

Fishery groups plan to sue PG&E over Potter Valley plant and related Scott, Cape Horn dams

Mary Callahan, THE PRESS DEMOCRAT

A coalition of fishery groups has formally notified PG&E that it plans to file suit under the Endangered Species Act, alleging the continued injury to once abundant federally protected salmon and steelhead trout as a result of operations at the utility’s aging Potter Valley powerhouse.

The legal maneuver is part of an effort to expedite removal of Scott and Cape Horn dams, which pose a threat to vulnerable fish species in the Eel River and block access to hundreds of miles of prime habitat upstream.

The plaintiffs contend that last Thursday’s expiration of PG&E’s license for the project means the utility is no longer protected from liability and must be found in violation of the Endangered Species Act — a point the utility disputes.

A formal notice filed Friday by the coalition gives PG&E 60 days to remedy the situation or face litigation. It also echoes comments about project inadequacies made in a March 16 letter from the National Marine Fisheries Service to the Federal Energy Regulatory Commission in advance of the expiration of the utility’s license.
