Hundreds of thousands of young salmon are believed to have died this week at the site of a historic dam removal project on the Klamath River, after an effort to restore salmon runs on the newly unconstrained river went awry, the Chronicle has learned.
The dead chinook salmon were among the first hatchery fish released on the Klamath since four hydroelectric dams were breached near the California-Oregon border, to allow the river to flow freely again and ultimately help fish flourish. One of the dams has been fully removed, and the three others are scheduled to come out later this year.
The salmon die-off, discovered downstream of the 173-foot Iron Gate Dam, is thought to be the result of trauma the small fish experienced when they went through a tunnel at the dam’s base, which had been opened to allow the river to pass and dam demolition to proceed. Water pressure in the outlet tunnel was presumably too great, causing the fish to die of what appears to be gas bubble disease, California officials told the Chronicle.
“No one, especially those in my program who work night and day to keep fish alive, wants to see something like this happen,” said Jason Roberts, an environmental program manager for the California Department of Fish and Wildlife. “We’re going to learn from it. We need to do better.”…
Planning documents projected that 5 million to 7 million cubic yards of sediment would be unleashed from the reservoirs, turbidity would increase and dissolved oxygen levels would drop in the river for several months and nonnative fish unaccustomed to cold river flows would die.
Two of the recently drained reservoirs, Iron Gate and Copco Lake, are in California. J.C. Boyle Reservoir is in Oregon.
“People are suggesting that this is an environmental disaster without acknowledging that we’ve had an environmental disaster for the past 100 years” with the dams, said Mark Bransom, CEO of the Klamath River Renewal Corp., which is shepherding dam removal. “These are anticipated conditions. The observations can be difficult. But we’re not going to undo the legacy of this environmental disaster in a couple of weeks.
“I encourage people to take a longer view,” he said.

I think the people in California would appreciate a few less excuses from the “geniuses” who are running our state and a lot more success. A baby salmon die-off resulting from a dam removal experiment is one thing. The possible carnage caused by automatic vehicles on the freeway, and weapons on our streets is another.
It is high time for someone to look at Citizens United and all the other bills that give preference to commerce over basic human rights to live in a healthy safe environment. The current legal system has severely diminished the value of human life and it is time for citizens to demand a change in priorities. Letters to the editor and author are encouraged.
