Mallard Cove and Old Camp 5 are car-top launching facilities with paved boat loading and unloading areas, toilets, and paved parking areas. Naturally produced and artificially stocked trout occur in the lake. Varieties are a Rainbow-Kamloops cross, German Browns, and Eagle Lake Trout. Other species include bass and catfish. Catfish are caught quite regularly and are very flavorful because of the cold water habitat.
