Area 1,157 acres upland, 4,973-acre reservoir. Primitive and modern camping facilities are present, and there are 13 hiking trails. Swanson Reservoir attracts many migrant water birds, some of which might overwinter. The wet meadows south of Stratton also attract many water birds during migration, including sandhill cranes and white-faced ibis. About 3,000 acres are open to hunting and other public use; this is the largest of the area’s reservoirs and has a large fish population, which should attract eagles and other fish-eating birds.
