Odell Lake is located near Willamette Pass in the northwest corner of Klamath County, Oregon, USA. It is one of several lakes in the Cascade Range of central Oregon and is located in the Deschutes National Forest. It was named by Bynon J. after Oregon Surveyor General William Holman Odell. The lake fills a basin carved by a glacier, and the resulting terminal moraine confines the water along the lake's southeastern shore.
