Snoqualmie Lake Potholes is a set of freshwater lakes located southeast Snoqualmie Lake, in King County, Washington. Self-issued Alpine Lake Wilderness permit required for transit within the Big Snow Mountain area.[3] Because Snoqualmie Lake Potholes are at the heart of the Alpine Lakes Wilderness, the lake is a popular area for hiking, swimming, and fishing rainbow trout and cutthroat trout.[4][1]
