Water Quality

In a cooperative partnership between Texas State University, the Texas Commission on Environmental Quality (TCEQ), and the U.S. Environmental Protection Agency, the Texas Stream Team actively monitors several sites (JPEG) throughout the Little Blanco and Cypress Creek sub-basins.

Data available through this site includes river monitoring results for 17 Texas Stream Team volunteer monitored sites and 2 USGS monitoring sites in the on the Lower Blanco River and its tributaries (Little Blanco and Cypress sub-basins).

According to our study, water quality impairments could be a direct result of over use and infrequent rainfall. Fish, macroinvertibrate, and plant metabolic and reproductive activities are dependent on water temperature ranges. As temperatures increase, the amount of dissolved oxygen in the water decreases. This can be particularly detrimental in shallow water bodies like the Blanco River where water warms more rapidly. Low DO level can cause asphyxiation in aquatic life.
