Description for Dworshak ReservoirDworshak Reservoir is created by Dworshak Dam which dams the north fork of the Clearwater River near Orofino, ID. The dam is the largest straight-axis dam in the Western Hemisphere. The reservoir stretches over 54 miles and is over 600 feet at its deepest point. The reservoir holds Kokanee and Largemouth Bass, but also has populations of Crappie, Rainbow Trout, and Cutthroat Trout. The Kokanee in the reservoir are abundant and usually 8 to 10 inches. The largemouth bass can be found on structure along the edges and grow to reasonable sizes.
The reservoir changes depth throughout the year. It is typically full through the 4th of July when the Army Corps begins to draw it down. Access can be a bit challenging when the reservoir is low. The reservoir is a major recreational spot for many in the area during the summer months.
