![]() Lake Chelan rests in a glacially carved trough in the Cascade Range in northwestern Washington. At 1,500 feet (457.2 m), it is one of the nation's deepest lakes offering opportunities for boating and fishing. A trip to the head of Lake Chelan is a journey into an unspoiled frontier, forgotten by time. Nestled in the deepest gorge in North America, Lake Chelan is one of Washingtons largest bodies of fresh water. Though the average width is less than two miles, the lake extends 55 miles into the heart of the Cascade Mountain Range with peaks that exceed 9000 feet. ![]() |
