Falls River Hydroelectric Project


The Falls River Hydroelectric Project is a 9.1 megawatt (MW) run-of-river project utilizing an existing irrigation diversion on the Fall River near Ashton, Idaho. Water is diverted and flows 5.5 miles paralleling the river through an enlarged power canal which is used jointly with the Marysville Irrigation Company. A 1.25-mile-long, 8.5-foot-diameter underground penstock carries project water to the powerhouse and a synchronous bypass valve at the edge of the Fall River. Power is generated by the project's two horizontal Francis turbine-generators rated at 4.55 MW each under 250 feet of head. The project began commercial operation in August, 1993. Operation and maintenance is performed by Ida-West Operating Services, Inc.
