Lost Creek Lake is located in Jackson County, 44 miles north and east of Medford on the Rogue River in a scenic, mountain and timbered canyon. Conservation measures preserve the ecological balance and retain the natural beauty of the terrain. The upper reaches of the lake are accessible only by boat.
Construction of the Lost Creek Dam was begun in 1972 and completed in 1977. The dam's unusual intake tower regulate water temperature by combining lake water from different depths in a mixing chamber and releasing it downstream. This cools the normally too-warm summer water of the Rogue River so that fish can flourish.
Several major public access areas, parks (including Joseph H Stewart State Park), boat ramps and a trail system surround the lake's 30 miles of shoreline. McGregor Park, dedicated in July 1977, was specifically designed for the convenience of handicapped visitors.
