Odell Lake is located near Willamette Pass in the northwest corner of Klamath County, Oregon, United States. It is one of several lakes in the Cascade Range in Central Oregon, and lies within the Deschutes National Forest. The lake fills a basin carved by a glacier, and the resulting terminal moraine confines the water along the lake's southeast shore. Odell Lake offers recreational opportunities similar to nearby Crescent Lake, which is 4 miles (6.4 km) to the south. There are several developed campgrounds around Odell Lake, as well as boat ramps that allow for sailing, wind surfing, water skiing and fishing.
