30 March 2007 � The Low Impact Hydropower Institute (LIHI) Board has certified the 465 MW Pelton Round Butte project as "low impact," based on an array of planned environmental protection measures, including a new fish passage system that will be under construction this fall. Pelton Round Butte is the second largest hydro project in the United States to receive the designation. Only one other Oregon facility has LIHI certification: the 430 MW Falls Creek Dam, northeast of Eugene.
LIHI certifies hydro projects after they have passed a series of tests that demonstrate minimum impact on fish and wildlife. Pelton Round Butte is unusual in that most certified projects are small dams, sometimes built in streams that have few migrating fish to begin with.
The project is owned by Portland General Electric Company and the Confederated Tribes of Warm Springs. The Federal Energy Regulatory Commission issued the project's new license in 2005.
