Staff Report & Agenda Item Details

2. Cross-validate non-exempt well records with database. we ESS | MAJOR AND HISTORICAL SPRINGS IN PECOS, REEVES, JEFF DAVIS, AND NORTHERN BREWSTER COUNTIES Review of Diamond Y Springs Hydrogeological Studies Image Source: The Nature Conservancy Veni (1991) and Boghichi (1997) • Identified separate spring systems within upper and lower watercourse • Veni (1991) considered influence of deep Permian waters and shallow mixing • Boghichi (1997) recognized Rustler as source waters Evaluate Diamond Y Springs Faults and Development of 3D Geologic Model • Standen and Sutherland (2021), Integrated geophysical log and other oil and gas data to delineate and map possible fault systems within the Diamond Y Spring area. Recommendations for Rustler Monitoring Wells (2022) • Identified several data gaps and possible wells that may be suitable for monitoring. Hydrostratigraphy and Fault Structure Refinements • Clause and Standen (2023) identified possible linkage between structure in Management Zone 1 and Diamond Y area. • Recommended expanded monitoring to better understand interconnection of Aquifer’s between management areas. Geochemical (Isotope) Framework Through Bureau of Reclamation and matched funding from MPGCD, Nunu and others (2024) sampled and performed statistical analysis on major ion chemistry to identify flow sources. • Diamond Y Springs have a unique hydrochemical profile. Rustler Brackish Groundwater Production Zones – Request for Amendments Recommendations • Formalize BGPZ amendment request to TWDB. • Consider a study to evaluate the recent regional rainfall events and the recharge effects on water levels.
