Plum Creek Water Quality Monitoring

Currently, routine ambient water quality data is collected monthly at 2 main stem stations by GBRA (#17406 and #12640) and quarterly at a third main stem station by the Texas Commission of Environmental Quality (TCEQ). The monitoring project, funded by US Environmental Protection Agency, through a grant from the Texas State Soil and Water Conservation Board (TSSWCB), will generate data of known and acceptable quality for surface water quality monitoring of main stem and tributary stations on Segment 1810, Plum Creek, for field, conventional, flow, bacteria and effluent parameters to support the development of a Watershed Protection Plan for the watershed.

Monitoring includes:

  • Routine ambient monitoring at 5 sites monthly, and one site quarterly over 15 months.
  • Targeted monitoring at 35 sites twice per season, once under dry weather conditions and once under wet weather conditions each season, for four seasons.
  • Automated stormflow monitoring at on urban/residential site during a minimum of four storm events.
  • 24-hour dissolved oxygen monitoring at 8 sites monthly during the index period.
  • Effluent monitoring of six wastewater treatment facilities, City of Lockhart plants(2), City of Luling, City of Buda, City of Kyle and Shadow Creek.
  • Springflow monitoring at three springs.
