Duck Creek rises seven miles northwest of Dickens on the eastern edge of the Caprock in northwest Dickens County (at 33°43' N, 100°57' W) and runs southeast for forty miles through southern Dickens and northern Kent counties to its mouth on the Salt Fork of the Brazos River, six miles northeast of Clairemont in east central Kent County (at 33°14' N, 100°41' W). Some of the first cotton in Dickens County was planted near the creek by Abel J. Hagins in 1889. Two years later Hagins built the first cotton gin in the county on Duck Creek. The stream, named for the numerous ducks that gathered at its water holes and small lakes, is the largest in Dickens County. In its upper reaches it crosses a flat flood-prone area with local shallow depressions. Water-tolerant hardwoods, conifers, and grasses predominate in this area, which has clay loam and sandy loam soils. In its middle reaches the creek enters an area of moderately steep slopes and locally high relief, with shallow to moderately deep silt loams that support mesquite and grasses.
