It is 21.4 miles southwest of Hood River, a 26.4-mile drive. The lake is bounded on the east by 4,468-foot Lost Lake Butte and on the southwest by 4,556-foot Preachers Peak. The lake is fed by three unnamed intermittent creeks from Lost Lake Butte, and Inlet Creek from Preachers Peak. The lake maintains a very consistent level via an outlet at the north tip, the source of Lake Branch Hood River, a tributary of West Fork Hood River. It is the second-deepest lake in Mount Hood National Forest after Wahtum Lake at 167 feet.
