The site serves as a major migration and staging area, with typical peak populations of 35,000 geese, 14,000 ducks, 10,000 sandhill cranes, and thousands of other marsh and water birds.
Long Lake NWR consists of approximately 15,000 acres of brackish to saline marsh and lake, 1,000 acres of other wetlands, and about 6,000 acres of tame and native grassland, woodland and cropland. This natural, non-tidal inland lake varies from 0.25 to 2 miles in width and is approximately 18 miles long. Periodically the lake goes dry. Similarly, during wet cycles the lake may reach overflow capacity with depths of 6 feet. Most years the lake experiences marsh-like depths of 1 to 4 feet.
