Snake River Dewatering July–Dec 2025
The City of Idaho Falls requests a temporary stop of the required minimum flows that would dewater about 1,100 feet of the Snake River bypass reach from approximately July to early December 2025 to allow construction of a cofferdam and maintenance on pelican gates. This action affects local river areas and could impact the environment in that reach during that period.
Public Comment and EA Schedule
The Federal Energy Regulatory Commission is accepting public comments on the variance request through March 31, 2025, and plans to issue an environmental assessment by June 27, 2025. The Commission's Office of Public Participation offers help to landowners, community organizations, Tribal members, and others who want to access information or file comments or interventions.
