This 3,430-acre reservoir sits on the Rogue River in the Rogue River-Siskiyou National Forest, approximately 34-40 miles northeast of Medford and 40 miles from Crater Lake National Park, near the town of Trail. Created by the William L. Jess Dam (managed by U.S. Army Corps of Engineers), Lost Creek Lake winds for 10 miles through paddle-friendly water with 30 miles of shoreline. The reservoir features numerous coves and tributary arms at the northeast and northwest corners. Average depth 136 feet, maximum depth 325 feet at the dam. Joseph H. Stewart State Recreation Area serves as the main access point with over 200 campsites and extensive day-use facilities.

Water Conditions & Skill Level Beginner to intermediate. Generally calm flatwater with paddle-friendly conditions throughout the 10-mile reservoir. Both motorized and non-motorized boats allowed – expect some boat traffic including water skiing and motorboats, especially on weekends. Big sandy beach at Joseph H. Stewart County Park ideal for launching. The lake’s size provides plenty of space for all users to spread out.

Stewart State Recreation Area (east bank), and McGregor Park boat ramp on Rogue River beyond the dam.
