SLOUGH CREEK. Slough Creek rises in a pool two miles northeast of Selfs in northeastern Fannin County (at 33°43' N, 95°53' W). It is named for the sloughs located near the mouth. The creek, which is intermittent in its upper regions, runs north for twelve miles to its mouth on the Red River, two miles north of Direct and two miles east of the Lamar county line in Lamar County (at 33°51' N, 95°47' W). In the area of the upper creek flat to rolling terrain with local scarps is surfaced by dark loam over clay to deep loams that support mesquite and grasses. Near the mouth low-lying flood plains are surfaced by clay loam that supports water-tolerant hardwoods and conifers.
