Water Levels
The GCUWCD measures water levels in over 100 observation wells across the district in the Wilcox, Carrizo, Queen City, and Sparta Aquifers. Water levels are measured three times a year in January, June, and September to assess seasonal changes in the Aquifers.
The water level data presented on the maps below will allow you to keep track of the depth to water in the observation wells throughout the year and also see the long term changes that have occurred since the water levels in the observation wells were first measured.
For example, on the Carrizo Map below find well No. 67-27-805 (located along the Guadalupe River near Belmont) and move the mouse pointer over the well point. The pop-up information box shows the well was first measured in January 1981 (Jan 1981) and the depth to water in the well was measured at 15.65 feet below the top of the casing. In January 2012 (Jan 2012), the depth to water was measured at 28.92 feet below the top of the casing.
The difference in the depth to water from the initial water level measurement taken in January 1981 to the January 2012 measurement is 13.27 feet which indicates that the depth to water in the well has declined approximately 13.27 feet feet in 31 years or about (0.43 feet per year).
