Directly ahead of you, across the road, is part of the Moss Lake floodplain. Moss Lake is a seasonal swamp created by springs, and the flooding of Mutton and Storm Creeks and the Muscatatuck River. The wetland, which varies in size between 100 and 500 acres, has attracted wildlife for hundreds of years. On the west edge of the refuge, Sandy Branch drains into Moss Lake and creates ideal Sandhill Crane habitat.
