The downstate bid for Mendocino’s Potter Valley Project
MENDOCINO CO., 5/15/26 — The Elsinore Valley Municipal Water District wants to buy the Potter Valley Project.
The district sits in Riverside County, more than 500 miles south of the Eel River. It has never run a hydroelectric dam. Its vice president, Darcy Burke, told a podcast in late April that her board considered the local plan to take Scott and Cape Horn dams down “criminal — their words, not mine,” she said. Its board president, Andy Morris, signed a letter to Congress last week saying the district has not made any decisions yet.
Rep. Jared Huffman, whose own district covers the Eel River basin, has been asking the same question many here are asking: why the interest from a Southern California utility in a far Northern California water project?
Three weeks ago Huffman sent demand letters to Morris and to two Trump cabinet secretaries who have been pushing the bid. Tuesday was his deadline for answers. Morris’ letter — surfaced to The Voice on Wednesday morning, four days after he signed it — is the only response so far, and it does not really answer the question.
So what is this really about?
Pumped storage is a way of using a dam as a battery. You build two reservoirs at different heights. When power is cheap — at night, or in the middle of a sunny afternoon when solar is flooding the grid — you pump water from the lower one to the higher one. When power is expensive, you let the water run back down through turbines and sell the electricity. The bigger the drop, the more power you can store.
Dave Steindorf works for American Whitewater, a national river-conservation group. He has worked the Potter Valley file for years. Hydropower is his beat. He looked at the Elsinore bid and asked the obvious question.
“Why would anyone buy a dam with significant seismic safety issues?” Steindorf said in an interview last week. “Not one pumped storage project has been constructed in the States for decades. The reality is that they just don’t pencil. Meanwhile, the amount of conventional battery storage that has been brought online is staggering.”
That is the question this story is about. The Potter Valley dams are not a normal asset to buy. One of them, Scott Dam, has known earthquake-safety problems. The federal hydropower license is being given up, not sold. The water itself belongs, under a federally approved local plan, to the Round Valley Indian Tribes and a coalition of Northern California agencies. The dams themselves are coming out.

So what is Elsinore actually after?
Two possibilities sit on the table. Neither one is the story Elsinore’s vice president Burke has been telling her own ratepayers. Neither one is what Trump cabinet secretaries have been writing on Twitter. The letter Andy Morris sent Rep. Jared Huffman last week — released to The Voice on Wednesday morning — keeps both possibilities alive without picking either one.
What’s at Potter Valley, in plain terms?
PG&E owns two dams on the Eel River. Scott Dam holds back Lake Pillsbury. Cape Horn Dam, the smaller one downstream, holds back Van Arsdale Reservoir. A tunnel sends a portion of Eel River water through the mountain into the East Branch of the Russian River. That water then runs down to Lake Mendocino. The diversion has run since 1908. It is the reason there is summer water in the Russian River. That is the reason there is wine in this part of California.
Last summer, PG&E filed to give up its federal license to run the project. The powerhouse has not made electricity since 2021. Scott Dam has serious earthquake problems. PG&E does not want it anymore.
Seven Northern California parties spent years working out what comes next. Sonoma Water. The Mendocino County Inland Water and Power Commission. The Round Valley Indian Tribes. Humboldt County. The California Department of Fish and Wildlife. CalTrout. Trout Unlimited. The plan they built — federally accepted — takes the dams out and keeps a smaller seasonal diversion in place to protect the Russian River farms and towns that have come to depend on it. That is the plan Darcy Burke called “criminal.”
Enter Elsinore
On April 21, U.S. Secretary of Agriculture Brooke Rollins posted on her official Twitter account that the Trump administration had found a buyer for Potter Valley: the Elsinore Valley Municipal Water District. Two days later, on April 23, Burke went on a ranching-advocacy podcast called AmericaUnwon and explained her board’s posture. “When I brought this issue to my board,” she said, “they said this was criminal — their words, not mine — and that they were going to do what they could to figure out how we can make this work.”

She said her phones started ringing the day after Rollins’s tweet. “People like, ‘Do you need a partner? Do you need a partner? Do you need a partner?’” she told the podcast.
On the same podcast she went after PG&E. The utility’s account of why no buyer ever came forward in earlier years, she said, “might be a version of the truth — maybe not the actual truth.”
PG&E answered through its spokesman, Paul Moreno, in writing. The utility laid out a timeline. Stakeholder outreach starting in 2017. A nationwide call for offers in fall 2018, run by an industry broker. “No viable proposals” returned. A January 2019 notice to federal regulators that PG&E would not seek a new license. A March 2019 federal “orphan process” that drew no applicants. The July 2025 surrender filing. And then a new disclosure: “PG&E met with Elsinore Valley Municipal Water District in January 2026.”
At that January meeting, PG&E has said, the utility offered Elsinore a non-disclosure agreement and urged the district to talk to the local coalition that is actually doing the work. “At this time,” the utility added, “Elsinore has not reached out to PG&E to have further discussions or sign an NDA.”
Two utilities, on the record, saying the other side’s account is unreliable. That is the ground on which Rollins’ framing of Elsinore as “a legitimate buyer” has to stand. It is also the ground Rep. Jared Huffman set out to walk Washington through.
Huffman, the senior Democrat on the House Natural Resources Committee, sent demand letters on April 28 to three people: Agriculture Secretary Brooke Rollins; Interior Secretary Doug Burgum; and Morris, the Elsinore board president.
A demand letter is what a member of Congress sends when he wants the executive branch to put something in writing. The Natural Resources Committee oversees the Interior and Agriculture departments. Both secretaries are subject to its inquiries.
Huffman has framed the bid as part of a larger play. Rollins, he has argued, is trying to federalize the Potter Valley Project — to pull it from PG&E’s surrender process into the Department of the Interior. She has brought Burgum into the effort. And she has named a Southern California buyer for PG&E’s water rights and infrastructure. The three moves together, Huffman has said, are cause for alarm.

He asked for everything. Any talks, plans, money, operations or impacts tied to a Potter Valley purchase. He also asked for any records connected to plans to “store, divert, transfer, sell, exchange, deliver or control” Eel River water for use outside the Eel and Russian River watersheds. The second part of the ask was broader than the first. It reached past the Elsinore bid to any policy that would move Eel water south.
In the press release announcing the letters, Huffman tied the Elsinore bid to the 1967 Dos Rios Dam plan — the federal plan to flood the Round Valley Indian Reservation and the town of Covelo. Public outcry killed that plan under Reagan. Huffman framed today’s bid as a direct heir.
What Riverside actually sent
By close of business Tuesday — Huffman’s deadline — none of the three recipients had publicly answered. Rollins and Burgum still have not.
Morris had answered. Privately. Four days early. The public did not see his letter until Elsinore’s public-information officer, Sylvia Ornelas, sent a copy to The Voice on Wednesday morning.
The letter says less than it seems.
It runs two pages. It says Elsinore is “in the early stages of its due diligence process” — the formal study a government body does before deciding whether to buy something. It says “no decisions have been made regarding acquisition, ownership, operations, financing, or any future use” connected to Potter Valley. It describes the district’s interest as a review of “water infrastructure and supply options that may provide broader benefits throughout California.”
That last phrase is doing the work. Water districts buying infrastructure for local use describe local use. “Broader benefits throughout California” is the language a district uses when the benefits of a deal are not local — when the prize is somewhere else.
The letter also acknowledged something Elsinore had never said before. Huffman’s request had two parts. The first was about the project itself — Scott Dam, Cape Horn Dam, the powerhouse, the water rights. The second was about plans to move Eel water out of the Eel and Russian River basins.
Morris told Huffman the district has records that match both parts. He did not say what those records are. He did not say how many. He told the congressman the district will start handing over the non-exempt ones by May 29, on a rolling basis after that. He reserved the right to keep back anything Elsinore decides is exempt under California’s public-records law.
A district that had not been thinking about moving Eel water south could have said so. Elsinore did not. It told Congress, in writing, that it has paperwork on the question. It asked for three more weeks before producing anything it is not calling exempt.
The letter does not mention electricity. The question this series has been asking Elsinore since April 27 — whether pumped-storage hydroelectricity is part of what the district is after — is not answered in the letter, and is not raised in it.
Why the pumped-storage question is not abstract
Lake Pillsbury sits at 1,818 feet. Van Arsdale Reservoir sits about 1,000 feet below it. That drop is in the same range as Castaic Lake — California’s biggest pumped-storage plant — and just below Bath County, Virginia, the biggest pumped-storage plant in the country. Lake Pillsbury holds about 80,000 acre-feet of usable water. Run that water through that drop, and the energy you could store works out to dozens of gigawatt-hours.
