Banks Lake is a 27 mile long reservoir in central Washington in the United States. Part of the Columbia Basin Project, Banks Lake occupies the northern portion of the Grand Coulee, a formerly dry coulee near the Columbia River, formed by the Missoula Floods during the Pleistocene epoch. Grand Coulee Dam, built by the United States Bureau of Reclamation on the Columbia River created Franklin D. Roosevelt Lake, the reservoir on the river behind the dam. A wide variety of fish are present in Banks Lake, including Largemouth Bass, Rainbow Trout, Smallmouth Bass, Sockeye Salmon, Walleye, and Yellow Perch.
