CALVERT CREEK. Calvert Creek rises two miles east of Interstate Highway 30 in southwestern Bowie County (at 33°18' N, 94°39' W) and runs southeast for five miles to its mouth on Wright Patman Lake, two miles west of U.S. Highway 67 (at 33°18' N, 94°37' W). Before the reservoir was constructed in the mid-1950s, the creek ran into the Sulphur River a mile east of Highway 67 (at 33°16' N, 94°36' W). The stream traverses flat to gently rolling terrain surfaced by sandy and clay loams that support grasses and mixed hardwoods and pines.
