Water Quality Monitoring

H-GAC, seven local partners and the regional TCEQ office coordinate monitoring for over 370 monitoring sites throughout the basins. This coordination is accomplished through quarterly meetings of the Regional Monitoring Workgroup. The workgroup convenes in March of each year to determine the sites that will be monitored in the following fiscal year. Changes in the schedule are determined by data analysis, recommendations of field or laboratory personnel, recommendations or requests related to needs in ongoing TMDLs, TMDL Implementation Plans or Watershed Protection Plans or changes to the budget. Changes to the schedule may include the addition or deletion of monitoring sites, addition or deletion of certain parameters, or a change in monitoring frequency. Sampling frequency is generally quarterly with some sights monitored as many as nine times per year. All monitoring is conducted under an approved H-GAC QAPP. All local CRP partners monitor the same suite of parameters, using comparable methods.

Special Studies

Water quality monitoring includes not only routine sampling but also special studies to address specific, previously-identified issues and local stakeholder concerns. Since 2006, H-GAC has completed or is completing DO monitoring projects, baseline assessment projects, flow studies, total suspended solids studies, and habitat surveys and characterizations. H-GAC is also working with stakeholders throughout the region to develop or implement Watershed Protection Plans.
