San Luis Lake is about half full. It is currently closed to motor boats but hand launched boats may be used. When the lake is at normal water levels, water skiing, motor boating, personal watercraft, fishing, sailing and windsurfing are popular activities at San Luis Lake. The 890 surface-acre lake is a sandy, shallow bowl with gently sloping sides and few hazards. The wide boat ramp and stable water level provides boaters with easy loading and unloading of vessels. All boats must remain south of the wildlife area buoy line at the north end of the lake to protect valuable waterfowl nesting habitat. San Luis Lake, at 7,519 feet in elevation, is the warmest body of water in the San Luis Valley. Swimming is not permitted in the lake. Colorado boating statutes and regulations apply and are enforced by park rangers.
