TR-558 Little River Continued Surface Water Quality Monitoring: Final Report and Data
Authors: Shaylynn Postma and Elena Lundeen
Throughout this project, supplemental water quality monitoring was conducted with a focus on collecting paired flow rate and Escherichia coli (E. coli) concentration data. Data were collected monthly for 18 months at TCEQ monitoring stations 11887 and 13546. Both stations were located on AUs with impairments or concerns for bacteria at the time of project design. All sampling procedures, methods, sampling sites, and planned project activities were fully described in a quality assurance project plan (QAPP). Monthly sampling included streamflow measurements, E. coli grab samples, and field parameters including temperature, dissolved oxygen (DO), specific conductivity, and pH. Water quality and quantity data were uploaded to the TCEQ surface water quality monitoring information system (SWQMIS) for use in future waterbody assessments. Water quality data collected as part of this project, findings, and trends are summarized in this final report to provide an informational basis for any future work conducted in the Little River watershed.
