The Lower Neches Valley Authority was established in 1933 by the state legislature as a district to store, control, conserve, and utilize the water of the lower Neches River valley in Texas. The LNVA, the second river district created by the state of Texas, is currently one of 23 river districts in the state. It includes all of Jefferson, Hardin, and Tyler counties and parts of Jasper, Liberty, and Chambers counties. The barrier, over 1,000 feet long, includes a 650-foot-long overflow barrier; five forty-five foot wide tainter gates; and a fifty-six foot wide navigation lane regulated by two thirty-foot sector gates. It also allows the conservation of 200,000 acre-feet per year of freshwater upstream in Sam Rayburn Reservoir.
