MARINE CREEK. Marine Creek rises east of Eagle Mountain Lake and two miles south of Hicks Field in northwestern Tarrant County (at 32°53' N, 97°25' W). It is dammed in its upper reaches near the Tenmile Bridge Road and Sansom Park Village to form Marine Creek Lake. The creek then runs southeast for ten miles to its mouth on the West Fork of the Trinity River, near St. Mary's Church (at 32°47' N, 97°20' W). It flows through the greater Fort Worth metropolitan area.
