Lower Granite Lock and Dam, Snake River, Washington and Idaho

Lower Granite Lock and Dam is the final component in the overall project to provide slack water navigation to Lewiston, Idaho. It involves construction of a dam, powerhouse, and navigation lock at river mile 107.5 on Snake River. An impoundment would be created bordering Whitman, Garfield, and Asotin Counties in Washington and Nez Perce County, Idaho. Backwater levees would be provided at Lewiston, Idaho. Railroad and highway relocations would be necessary. Activities associated with the free-flowing river would be eliminated. Riparian vegetation would be eliminated and fish habitat would be altered to the detriment of certain species. Relocation and construction work would create an impact upon the landscape in and near the canyon bottom. Construction of levees at Lewiston would cause temporary disruption and noise near the community as a result of equipment operation and earthwork.
