The Twisp River Cattle Management Project provides riparian protection for Upper Columbia Steelhead in the Twisp River Watershed. The project was done on federal lands in partnership with the United States Forest Service (USFS).
Dramatic declines in the abundance of anadromous Pacific salmonids have occurred over the last century in the Columbia River basin. Population declines followed harvest, hydrosystem and watershed development, habitat loss and degradation, and reduced survival in freshwater, estuary, and marine environments. These declines are accompanied by greatly reduced levels of natural production due to an array of anthropogenic factors.
