One way is to check the state driller’s reports by locating your well on the map and reviewing the report for the GPM when the well was built. Another way would be to contact a licensed driller for well testing.

The Evergreen Underground Water Conservation District (EUWCD) is a groundwater conservation district created by the Texas Legislature in 1965 under the authority of Section 59, Article XVI of the Texas Constitution. The District is responsible for the conservation, preservation, protection, and prevention of waste of groundwater resources in its jurisdiction. EUWCD regulates groundwater through well permitting, monitoring, and public education in accordance with Chapter 36 of the Texas Water Code and its adopted rules and management plan​​.

The EUWCD encompasses four counties in South Texas: Atascosa, Frio, Karnes, and Wilson. The boundaries of the District are coterminous with those of these counties, covering approximately 3,917 square miles​.

EUWCD is governed by a Board of Directors composed of nine members. Two directors are elected from each of the four counties, and one director is appointed by the Governor of Texas. The Board adopts and enforces rules, issues permits, and oversees the District’s operations in accordance with state law​.

The District office is located at:
