Staff Report & Agenda Item Details

Update and possible action on Pecos County Groundwater Flow Model and Timeline on Tech Memos. A new draft tech memo has been created for the model grid and in support of model development. That tech memo and all the tech memos have been and continue to be on the District's webpage with peer review and feedback encouraged. Belding Farms Data processed 5600 data points from 1957 to 2023. TWDB had over 47,000 water levels from 1940 to 2024. EcoKai transducer data from FSH joint study had over 500,000 data points for 2021-2024. LRE and the Halff data management system had 15,000 groundwater data points. While calibrating the database we realized all the data from numerous studies have not been added to the database. Several discrepancies were recognized on some of the Belding Farms’ wells for elevations compared to the model grid. Belding Farms corrected the coordinates on the suspected wells and LRE updated the database. We have finalized the pumping data and Spring locations and are beginning to look at the recharge analysis that will need to be completed. All tech memos associated with the model can be assessed at the following google link: https://drive.google.com/drive/folders/1HY|8JRV4omAgKPJWBta-T20hZUbtyaPS 2usp=drive_link Page 40f 8 Minutes of 01-21-2025 xl XIl
