Swift Lake is about 17 miles long and 2 miles wide. It's maximum depth is about 330 feet. This lake is behind a rock dam and hydroelectric plant, created in 1958, managed by PacifiCorp. The Lewis River drains from Mt. Adams and Mt. St. Helens' through three reservoirs then into the Columbia River near Woodland, WA. Campgrounds and boat launching parks on the north east side of the Swift Lake provide some access points operated by Pacific Corp, e.g., Swift Forest Camp.
We have good maps of the Gifford Pinchot National Forest area. We also have very good maps of Clark, Skamania, and Cowlitz Counties.
