HARRIS CREEK (Grayson County). Harris Creek rises three miles west of Sherman in central Grayson County (at 33°38' N, 96°41' W) and runs northwest for ten miles, passing into the Hagerman National Wildlife Refuge before reaching its mouth on the Big Mineral Arm of Lake Texoma, twelve miles northeast of Whitesboro (at 33°44' N, 96°45' W). The stream, which is intermittent in its upper reaches, traverses flat to rolling prairie, surfaced by soils ranging from dark, commonly calcareous clays to clay and sandy loams. Local vegetation includes mesquite, water-tolerant hardwoods, conifers, and various grasses. The area has been used for range and crop land.
