The first of three lawsuits filed against Winchester Water Control District, the owners of Winchester Dam, completed its bench trial in Federal Court in Portland on Monday, April 21, 2025.
The legal bills for this litigation will cost hundreds of thousands of dollars which must be paid collectively by the approximately 100 members of the Winchester Water Control District —the homeowners who live around the private water ski lake behind the Winchester Dam.
The Federal Endangered Species Act case, filed against the Winchester Water Control District in the U.S. District Court in Portland, on November 6, 2020, on behalf of endangered Coho salmon by plaintiffs WaterWatch of Oregon, Steamboaters, the Pacific Coast Federation of Fishermen’s Association, Institute for Fisheries Resources, Craig Law Center, and attorney Karl G. Anuta, was the first case to be heard.
As is his usual strategy Dominic Carollo, the attorney representing the Winchester Water Control District, has made numerous motions to delay this trial. A total of sixteen months of delay were granted by the Judges, as well as a protective order requested by the Winchester Water Control District against the plaintiffs.

After the Winchester Water Control District requested the case be dismissed, it took another eight months for Judge Immergut to decide whether the case should proceed.
When the WWCD requested all plaintiff expert witness testimony be excluded from the case, it took a few months for Judge Immergut to deny Winchester Water Control District’s motion and decide to allow expert witness testimony.
When National Oceanic and Atmospheric Administration completed its National Marine Fisheries Service (NMFS) biological opinion of the 2023 Winchester Dam reconstruction, the Winchester Water Control District emailed the 69-page report to the Army Corp of Engineers—but refused to provide the Plaintiffs with a copy, claiming it was “unduly burdensome.”
It took six weeks for Judge Immergut to order the Winchester Water Control District to provide the plaintiffs with a copy of the NMFS.

When post-trial briefings are completed, U.S. District Court Judge Karin J. Immergut is expected to announce her rulings on this case sometime this summer.
