Brazos River, the streams and lakes along the river are a major source of public water supply for drinking and agricultural uses for communities in around the Brazos River basin. Segment 1242 of Brazos River and the watersheds (Leon River watershed and Lower Brazos-Little Brazos watershed) and their tributaries flowing into Brazos river in this segment are known to be impaired for bacteria, salts, nutrients and chlorophyll-a (TCEQ, 2013). The flow of nutrients from rain water run-off from land into Brazos River results in eutrophication of the river and algae (Chlorophyll-a) bloom, thereby reducing the dissolved oxygen content in the water. This hypoxia in the water causes the death of fish and other living organisms in the river. This can contribute to the eventual increase in the size of the dead zone in the Gulf of Mexico when the Brazos River flows into the Gulf. Bacteria flow and salt flow from natural sources into the river also degrades the quality of the river for recreational and agricultural uses.
The rising cost of water treatment makes the impairment of Brazos River and its tributaries a major concern for the state of Texas, hence protecting and managing the water quality of Brazos River and its watersheds from pollution is very important before the water can be made available for public supplies. In order to manage the water quality efficiently, it is very important to understand the relationship between pollutant / effluent loads and rainfall events; influent…
