Aerial photo of Lower Granite
An aerial view shows Lower Granite Lock and Dam passing water through its spillways, April 26, 2019. Lower Granite Dam is one of four lower Snake River dams and located near Pomeroy, Washington. It provides hydropower generation, navigation, fish and wildlife habitat, recreation and incidental irrigation. Officials from the U.S. Army Corps of Engineers (USACE) and Washington State have entered into agreements to study recreation- and transportation-related services that could be needed if, in the future, Congress were to authorize the breach of the four lower Snake River dams. The studies are part of USACE’s broader commitments under the December 2023 Resilient Columbia Basin Agreement, which secured a long-term stay in litigation while supporting the restoration of healthy and abundant wild salmon, steelhead, and other native fish to the Columbia River Basin.
