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 LNVA is governed by a board of nine directors appointed by the Texas Water Development Board. Until 1943 the authority was without any facilities to produce revenue. Since 1943 the irrigation system has been renovated many times. It supplies water to the cities (except Beaumont), industry, and rice growers of Jefferson County and portions of Chambers and Liberty counties.
The LNVA has also cooperated with the United States Army Corps of Engineers in planning, financing, and constructing several large multipurpose dams on the Neches River and Angelina River. Other projects sponsored by the authority include the construction of a permanent saltwater barrier on the Neches River, a comprehensive water-quality management program, and the construction of boat ramps and other recreational facilities on area waterways.
The LNVA system includes 400 miles of canals covering a 700 square mile area. The canals deliver fresh water to "...eight cities and water districts, 26 industries, and over 100 irrigated farms..." Water is drawn from the lower Neches River and Pine Island Bayou in north Beaumont, with 21 large pumps delivering between 20,000 and 110,000 gallons of water a minute; it has a capability of delivering more than one billion gallons of water a day.
Prior to construction of the permanent barrior, the LNVA installed temporary barriers across Pine Island Bayou and the Neches River upstream of their confluence 36 times between 1940 and 2000, to prevent contamination of their waters from salt water.
