Connecting Dam Removal, Indigenous Cultures, and Native Fishes

UC Davis Professors Beth Rose Middleton Manning and Robert Lusardi recently published a compelling piece in the online news publication “The Conversation.” In “Removing dams from the Klamath River is a step toward justice for Native Americans in Northern California,” the authors explore the connections between the removal of four Klamath river dams and the ways in which returning the river to health will benefit both the people who have called the Klamath Basin home since time immemorial and the fish populations that rely on the river for survival.

Implications of Sediment Release in the Klamath River

Beginning in January 2024, reservoir drawdown and removal of the four Lower Klamath Project dams will cause the release of impounded sediment into the Klamath River below the site of Iron Gate Dam and exposure of sediments in the reservoir footprints. Peak concentrations of sediment – mostly dead algae, clay and fine material the consistency of talcum powder – will occur in the first few months following drawdown of the reservoirs. Modeling of sediment transport shows that suspended sediment will tend to spike in January/February 2024, with a second spike in June/July of that year, tapering off afterwards. What does that mean for downriver communities, for fish, and for the entire Klamath River ecosystem? Continue Reading Implications of Sediment Release in the Klamath River

Update on Copco No. 2

The deconstruction of Copco No. 2, the smallest of the four hydroelectric dams being removed from the Klamath River, is underway. This week, crews removed the gates, walkway, and two of the five bays down to the spillway. This work was done to direct waters around the dam, rather than over it, allowing construction crews to do work through the summer months. Continue Reading Update on Copco No. 2

Klamath Dam Removal Construction: What’s Happening, What’s Next

The Klamath River Renewal Corporation (KRRC) officially broke ground on the Klamath dam removal project on March 10. The dam removal contractor, Kiewit Infrastructure West (Kiewit), is in the field preparing for reservoir drawdown and dam removal in 2024. Kiewit is currently working on pre-drawdown construction work and the rest of 2023 will be spent on the early construction work necessary to prepare for drawdown of the reservoirs beginning in January 2024, followed by removal of the dams later in 2024.

When nature shouts, “Look at me!”

A superbloom doesn’t happen often, but when it does you can see it from space. Seeds that have long lain dormant in typically dry swaths of California soils explode in a wild splash of hues during unusually wet periods. And boy has 2023 been unusually wet! The stunning result in many places is a landscape painted with broad strokes of eye-popping color as drought-adapted species awaken from slumber. Continue Reading When nature shouts, “Look at me!”

Restoring the Klamath River: Science informs where future runs may go

On November 17 the Federal Energy Regulatory Commission (FERC) issued the Final License Surrender Order for the Lower Klamath River Hydroelectric Project. With this final regulatory hurdle now crossed, the Klamath River Renewal Corporation and its local Tribal and nonprofit partners can remove the four lower Klamath River Dams located on both sides of the California/Oregon border over the next two years.
