TR-555 Middle Yegua and Davidson Creeks Continued Monitoring Final Report and Data
Authors: Elena Lundeen and Amanda Tague
Throughout this project, routine water quality monitoring was conducted with a focus on E. coli concentration data. Data was collected monthly for 32 months at six sites, including TCEQ monitoring stations 18750, 11840, and 11838 in Middle Yegua Creek (Figure 1) and 11729, 21420, and 18349 in Davidson Creek (Figure 2), resulting in 192 total monitoring events. Out of the 192 monitoring events, only 187 water grab samples were collected due to some monitoring sites running dry. All sampling procedures, methods, sampling sites, and planned project activities are fully described in the project quality assurance project plan (QAPP). Monthly sampling included field parameters, streamflow measurements, and E. coli grab samples.
Water quality and quantity data was uploaded to the TCEQ surface water quality monitoring information system (SWQMIS) for future waterbody assessments. Collected data, water quality findings, and trends are summarized in this final project report to provide an informational basis for any future work conducted in these watersheds.
