EA-2022: Sleeping Giant Hydropower Project; Helena, Montana

The Bureau of Reclamation (Montana Area Office), with DOE’s Western Area Power Administration (Upper Great Plains Region) as a cooperating agency, prepared an EA to assess the potential environmental impacts of a proposal to develop a 9.4 megawatt hydroelectric project at the existing Helena Valley Pumping Plant site at Canyon Ferry Dam on the Missouri River near Helena, Montana. The new hydropower generator would interconnect to Western’s transmission system at an existing transmission line originating at Canyon Ferry Dam.
