Untreated wastewater spill reported in lower Russian River, people urged to ‘stay away’

People are being asked to stay away from the lower Russian River after an unknown volume of untreated wastewater spilled from a sewage treatment plant in Guerneville during the tail-end of a storm that drenched Sonoma County and flooded many roads across the region.

Heavy overnight rainfall — part of the region’s prolonged atmospheric river — caused storage ponds at the facility to overflow early Tuesday morning, said Stuart Tiffen, a spokesman for Sonoma Water, which operates the Russian River Treatment Plant.

Affected residents were alerted of the spill Tuesday morning, officials said.

Tiffen described the spill as an “ongoing situation” and said it is currently unknown how many residents are impacted or how much wastewater, including raw sewage, is spilling into the river.

Op-Ed: If feds want Potter Valley dams, they should buy them

December 28, 2025

PRESS DEMOCRAT EDITORIAL

President Donald Trump’s California derangement syndrome is back as his administration tries to prevent PG&E from removing aging dams in the Potter Valley Project.

Agriculture Secretary Brooke Rollins has moved to intervene in the Federal Energy Regulatory Commission process to determine whether PG&E may tear down two dams and a mothballed powerhouse. Rollins wants FERC to deny the application.

Agriculture secretaries often get involved in these sorts of proceedings. Major changes to watersheds can impact farmers, after all. What is unusual in this case is that in supporting irrigators, a supposedly pro-business administration undermines private enterprise.

PG&E wants to surrender its license for the hydropower system on the Eel River because it now costs more than it is worth. The dams and powerhouse are more than a century old and are nowhere close to meeting modern standards. They require costly repairs and upgrades to remain safe. PG&E absorbs those costs, and no doubt passes some onto ratepayers.

Trump administration intervenes in dispute over future of Potter Valley Project

Opponents of a plan to remove two Pacific Gas & Electric-owned dams from the Eel River in Lake and Mendocino counties have officially won a huge ally: the Trump administration.

Agriculture Secretary Brooke Rollins on Friday filed a notice to intervene in the utility giant’s bid to decommission its waterworks in the rural area, which also include a century-old power plant that helps to shunt Eel River water into irrigation canals that support Mendocino County’s Potter Valley and dump into the upper Russian River, boosting supplies for farms and hundreds of thousands of urban dwellers in the North Bay.

PG&E’s application to decommission the so-called Potter Valley Project is being considered by the Federal Energy Regulatory Commission, or FERC, which oversees licensing of the nation’s hydroelectric facilities.

Developer of Cloverdale resort project seeks to assure city, public of adequate water supply

One question has been dogging the backers of a proposed housing and resort project vying to transform Cloverdale’s long-stalled Alexander Valley Resort site and remake the look of Sonoma County’s northernmost city.

Will there be enough water?

Representatives for Esmeralda Land Company insist there is, citing reports from a consultant the Bay Area developer hired for their ambitious project, which calls for 605 homes — in a mix of apartments, town homes and single family homes — two hotels and two restaurants on 266 acres off Asti Road.

Devon Zuegel, the principal of Esmeralda will be on hand Wednesday at the Cloverdale City Council meeting to field questions focused on water demands tied to the project, which also includes a racquet club, two indoor pavilions, an outdoor amphitheater, retail space, light industrial facilities, a K-6 private school and a standalone office building.

It would also have more than 1.8 million square feet of landscaped area, including a dog park, community garden and playground. The project is conceptualized to be a walkable, bikeable community for multiple generations, according to Zuegel.

Green Valley revival reconnects creek to floodplain

A partnership between Iron Horse Vineyards, the property owner, and the Gold Ridge Research Conservation District (Gold Ridge), with funding from California Fish and Wildlife and the National Oceanic and Atmospheric Administration Restoration Center (NOAA), has restored and improved a large part of the middle reach of Green Valley Creek to provide overwintering habitat for coho and steelhead salmon. Construction on the project, which took years of planning, began in April and has recently been completed.

“Now it is up to nature, assisted by teams of workers planting native grasses and willows to restore what has been lost for over a century and bring back healthy salmon to the creek and the Russian River,” said chief scientist and project manager John Green.

Green Valley Creek was once considered critical habitat for salmon because of its proximity to the Atascadero Plain, offering one of the largest basins for young salmon to grow strong enough to survive ocean challenges and return to breed.

This area of the creek, at the bottom of the Iron Horse vineyard property, was once a flat field, prone to annual flooding and quick drainage. It offered no shelter for fish or the insects that support them. Now, after years of planning and months of construction reshaping, the site hums with quiet anticipation as a stream begins to come back to life.

PG&E files application to decommission Potter Valley Project

July 25, 2025

The utility formally has filed its plans to shut down the two Northern California dams and century-old powerhouse that comprise the project.

Pacific Gas & Electric Co. has filed its formal plans with the federal government to decommission the Potter Valley Project, which includes two dams and a century-old powerhouse that together have helped connect the Eel and Russian River watersheds to provide water to cities and farms for generations.

The filing marks another step in the power company’s multiyear effort to divorce itself from the two-dam system — Scott and Cape Horn dams — that PG&E officials say has been operating at a deficit of $1 million a year.

“Today’s filing marks the next step of a thoughtful and transparent decommissioning journey for the Potter Valley Project — but it does not change our operational responsibilities or obligations,” Dave Gabbard, vice president of power generation for PG&E, said in a press release.

If approved by the feds — no such request has ever been denied — plans would kick into motion the next large dam removal project on the West Coast.

A to-be-drained lake, a PG&E plan, and the promise and peril of California’s next big dam removal

LAKE PILLSBURY — A cool May breeze lapped across the surface of this reservoir in remote Lake County, where a couple made their way out in a boat across otherwise serene waters, taking advantage of the brightest bit of afternoon sun.

This man-made retreat, four square miles of water impounded by a dam across the upper Eel River, feels durable. It’s filled with hungry trout and black bullhead, prey for the sharp-eyed bald eagles, egrets and herons that hunt these waters.

To many of its visitors, and the several hundred people who live along its 31-mile shoreline deep within the sprawling Mendocino National Forest, Lake Pillsbury is the region’s heartbeat.

But Scott Dam, at the foot of Lake Pillsbury, and another, smaller dam on the river 12 miles downstream, have also become a headache for Pacific Gas & Electric Co., which owns both dams.

And that’s creating a controversy that’s drawn interest from everyone from those who live on Lake Pillsbury, to North Bay communities whose water supplies are linked to both dams, to federal agencies now under control of President Donald Trump.
