North Bosque River: Continuous Water Quality Monitoring

Operations of continuous water quality monitoring stations on the North Bosque River near Clifton.

Background

The North Bosque River (Segments 1226 and 1255) originates near the Stephenville and flows southeast over a primarily rural landscape, eventually flowing into Lake Waco (Segment 1225). Nutrient and algal concentrations in excess of screening levels established by the TCEQ have been found since 1996. Excessive algal growth can lead to taste and odor problems for drinking water and can cause low levels of dissolved oxygen within a stream, which could kill fish.

In response to water quality concerns, the TCEQ completed two total maximum daily loads (TMDLs) for phosphorus, the limiting nutrient of the watershed, in 2001. A subsequent TMDL Implementation Plan (I-Plan) was adopted in 2003. Dairy-waste application fields and municipal wastewater-treatment plants were shown to be the major controllable sources of phosphorus in the watershed.

Since approval of the I-Plan, many projects and activities have been put in place to control and remove sources of nutrient loadings in the watershed. To assess the effectiveness of these activities in improving water quality, the TCEQ installed many monitoring stations  in the watershed. It is important to continue this monitoring to assess progress.

Project Description

For this project, the Texas Institute for Applied Environmental Sciences is continuing operation of two existing stations of the continuous water quality monitoring network near Clifton and SH 6. The data from these stations are helping the staff of the TCEQ Stephenville field office to:

  • target field investigations to likely sources when pollutant concentrations exceed trigger levels
  • supply quality-assured water quality data to support evaluation of implementation
