Army Corps Releases Final Report on Snake River Dams

The U.S. Army Corps of Engineers released last week its final report on improving salmon passage through the lower Snake River dams, reaffirming its recommendation to make major systems improvements to the dams, as was first announced in December. The Corps report rejected the option of breaching the dams, which would have eliminated 3,033 megawatts of hydroelectric power capacity for the region — about 7 percent of the region's total generating capacity. The newly released feasibility report and environmental impact statement provides the basis for the Corps' recommendation and includes details of the recommended system improvements.

The recommended improvements include structural changes such as upgraded fish ladders (to aid adult fish migrations upstream) and turbine upgrades. The report also recommends operational changes such as improved spills of water past the dams to assist with juvenile fish migration downstream. The Corps is accepting public comments on the report through early April. See the Corps' Walla Walla District press release (PDF 17 KB). Download Acrobat Reader

The full report is loaded with photos and illustrations, and is actually quite educational. However, the download times are long, so you might opt to order a compact disk. Both options are available on the Web site.
