Groundwater levels provide critical information about the hydrologic relationships of recharge and discharge to storage within an aquifer, and the direction of groundwater flow. The District maintains over 40 monitor wells to track water levels using continuous-recording instruments or periodic manual measurements. The District monitors groundwater levels within the Edwards, Upper and Middle Trinity Aquifers. Monitor well types vary from operational water-supply wells to specialized multiport well systems. Hourly data is collected, reviewed for quality assurance, and entered into a database.
Long-term, systematic measurements of water-level data are essential for the District’s drought management and conservation program, and for the Aquifer Science team for hydrogeological studies.
