Sprague Lake is approximately 36 miles west of Spokane along I-90. The lake is roughly 6 miles long and fairly shallow throughout with a maximum depth of 20 feet. Because of its shallow depth the lake produces good insect hatches. The fishing is best in the Spring and the Fall but can be difficult in the Summer due to an abundance of algae blooms. The lake is abundant with Rainbow Trout with an average size of 12-16 inches. Other species include Cutthroat Trout, Largemouth Bass, Channel Catfish, Crappie, and Perch. Fishing is available from both shore and boat.
