Idaho agriculture is the second largest user of water for irrigation in the US and diverts more water for aquaculture than the rest of the US combined. Idaho has more than 93,000 miles of streams, with over 3000 miles of world-class whitewater. These streams contain 19 species that are endangered, threatened, or species of concern. Over 900 rivers or river segments have been designated as impaired for water quality with the primary concerns being fine sediments and temperature. There are also concerns regarding geomorphic and ecological integrity of streams in the face of these stressors. The Center for Ecohydraulics Research conducts research relevant to water challenges in Idaho and the west, and receives advice and direction from State and Federal agencies to ensure research relevance. Recent local and regional projects have been performed in collaboration with the U.S. Forest Service, the U.S. Bureau of Reclamation, the Columbia River Inter-Tribal Fish Commission, the Kootenai Tribe, Idaho Power, the City of Boise, Boise Flood Control District, and the Idaho Department of Water Resources.
