The ROD adopts the preferred alternative developed through the agencies’ environmental impact statement process. The decision recommends a limited increase in the amount of water spilled over the four dams on the Lower Snake River, but allows the dams to stay in place at a significant cost to salmon, steelhead, tribes, anglers, and communities across the Columbia Basin.
Trouble in Idaho
By Michael Gibson: No matter how you frame it, wild steelhead in Idaho are in big trouble. While wild steelhead numbers have never really rebounded—as expected—after the listing of the species in 1997, 2017 and 2018 returns have been exceptionally poor. In 2017, fewer than 12,000 wild fish cleared Lower Granite Dam, the last of the lower …
Science Friday: Warm water’s influence on the speed of upstream migrating steelhead
The dog days of summer are fully upon us. The predicted forecast for adult summer steelhead returning to the Columbia and Snake River basins is now, unfortunately, shaping up to be worse than expected (and it was already very low). However, it can be difficult to determine how accurate this forecast actually is because at this point in time the …
Science Friday: Hitch-Hiking Smolts
Last week we talked about the importance of spill for out-migrating kelts and smolts in the Columbia Basin. Increasing spill is only one method employed to enhance downstream survival of smolts. As early as the mid-1950s smolts were loaded onto barges and moved downstream past the dams through the lock system. While fisheries managers experimented with this tactic early on …
