Spill Kills Fish by Marvin F. Dugger Lewiston Tribune, December 15, 2026

Fisheries biologist John McKern did a great job in his Sept. 6 Tribune column explaining the history of our Northwest anadromous fish populations and the problems they face.

Standard total dissolved gas, or TDG, levels were established by the Environmental Protection Agency in 1971. Levels above 105% for juveniles and 110% for adults were determined to be lethal. Some highly qualified fish biologists in our organization have studied this extensively and found no scientific studies that dispute these facts. The EPA standard's still in effect to this day.

Three times, Oregon federal judges have ignored these facts and ordered high spill at the dams. In 2005, Judge James Redden ordered 120% TDG at the four lower Snake River dams. After he retired, Judge Michael Simon, who replaced Redden, increased the TDG order to 125% in 2016. Then in 2026, Judge Simon placed these orders on four more dams, including Bonneville. Prior to this 2026 order, Judge Simon was provided three amicus briefs from biologists in our organization explaining the lethality of these TDG levels, but he ignored them. At least 140 million fish have died as a result of this court order and many more will perish as this failed experiment continues.

Join us at Citizens for the Preservation of Fish and Dams, Inc., citizensforfishdam@gmail.com and cfpfd.org. Help us stop this terrible crime perpetrated by radical environmental groups, who want to tear out our dams, before our salmon and steelhead are tragically driven to extinction and our dams needlessly destroyed.
