The Neches River begins in Van Zandt County east of Rhine Lake and flows for 416mi through east Texas to its mouth on Sabine Lake near the Rainbow Bridge. Two major reservoirs, Lake Palestine and B. A. Steinhagen Reservoir are located on the Neches. Several cities are located along the Neches River Basin, including Tyler, Lufkin, Silsbee, Evadale, Beaumont, Vidor, Port Neches, Nederland, Groves, and Port Arthur.Untamed riverWith the exception of the manmade lakes, much of the river is in a natural state. For example, from Lake B.A. Steinhagen down to Beaumont, the Neches River flows through the Big Thicket National Preserve. This important ecosphere preserves the area where several ecosystems converge - an event that harkens back to the last glacial period. The Big Thicket Visitor Center is off U.S. Highway 69 several miles north of Kountze.
