Lake Lenore, also known as Lenore Lake, is a lake in Grant County, Washington, United States. It is a 1,670-acre (680 ha) lake formed by the Missoula Floods in the lower Coulee just north of the town of Soap Lake, Washington. It is situated between Alkali Lake to the north and Soap Lake to the south. The lake is rather narrow, but long. The length of the lake runs north–south alongside State Route 17 leading from near the city of Soap Lake to Coulee City. Lenore Canyon is a coulee associated with the development of the Scablands.
