EDWARDS UNDERGROUND WATER DISTRICT

EDWARDS UNDERGROUND WATER DISTRICT. The legislature established the Edwards Underground Water District in 1959 for the purpose of conserving, protecting, and recharging the waters of the Edwards Aquifer. Current programs of the EUWD include water quality investigations, water level monitoring programs, recharge enhancement activities, and water conservation projects. Since the mid-1970s the EUWD has constructed four recharge dams in Medina county, including the Middle Verde Creek Dam (1978), the San Geronimo Creek Dam (1978), the Seco Creek Dam (1982), and the Parker Creek Dam (1984). The district has also funded several studies concerning enhancing recharge to the Edwards Aquifer, including the Medina Lake Recharge Study and the Nueces Basin Recharge Study (funded in cooperation with the City of Corpus Christi, South Texas Water Authority, and the Texas Water Development Board). In 1987 the EUWD developed the state's first regionwide Drought Management Plan. Employees also worked in cooperation with the city of San Antonio in 1988 to develop the area's first Regional Water Study that later formed the basis of the Regional Water Plan. In 1989 the district launched the first regionwide municipal leak detection program in south central Texas. This service is available at no charge to cities and water distribution systems throughout the region. The district also maintains one of the most comprehensive data collection programs in Texas for an underground water supply. A network of over 100 monitoring wells, located throughout the Edwards Aquifer region, enables the district to maintain constant watch over water quality and quantity. Some of their most diligent conservation efforts in recent years have been in the monitoring and protection of the sensitive Edwards Aquifer Recharge Zone. In conjunction with the United States Geological Survey, the EUWD does annual calculations of recharge to the underground formation in the upper portions of the Nueces, San Antonio, and Guadalupe river basins, which are hydrologically connected by the underground reservoir. The average recharge in 1993 was 447,600 acre-feet of water. The original district included five counties: Uvalde, Medina, Bexar, Comal, and Hays. In 1989 Uvalde and Medina withdrew from the district. The EUWD in 1994 was governed by a board of directors elected by popular vote, representing the counties of Bexar, Comal, and Hays. A general manager oversaw three divisions: administration, field operations, and environmental management and planning. In 1989 the legislature revised their charter to give the EUWD authority to implement drought management plans. The district employed thirty-three people in 1994.
