Joseph H. Stewart State Recreation Area is an Oregon state park on the Rogue River in southern Oregon, administered by the Oregon Parks and Recreation Department. About 40 miles from Crater Lake National Park and 35 miles northeast of Medford, it occupies a river-and-reservoir setting where campsites overlook Lost Creek Reservoir. The park serves both as a recreation destination in its own right and as a convenient base for exploring this section of the Rogue River corridor.
