EAST FORK OF THE ANGELINA RIVER. The East Fork of the Angelina River rises at the junction of Ham Creek, Double Tree Branch, and several other small streams, three miles northwest of Mount Enterprise in southern Rusk County (at 31°57' N, 94°44' W), and runs southwest for nineteen miles to its mouth on the Angelina River, near the Nacogdoches county line two miles southeast of Reklaw (at 31°51' N, 94°56' W). It traverses flat to rolling terrain surfaced by sandy and clay loam that supports water-tolerant hardwoods, conifers, and grasses.
