Delta Lake is a freshwater lake located in the Alpine Lakes Wilderness, north of the Necklace Valley lakes in King County, Washington. Because Delta lake is at the heart of the Alpine Lakes Wilderness, the lake is a popular area for hiking, swimming, and fishing rainbow trout, and cutthroat trout. Delta Lake is a consequence of the spill of the outlets of three major Alpine Lakes: Otter Lake, Big Heart Lake, and Angeline Lake. The West Fork of the Foss River exits Delta Lake in two outlets which merge into one stream shortly above the top of Upper Foss River Falls.
