Project Background and Goals

The North Bosque River and Waco Lake, formed by an impoundment of Bosque River, serve as the primary drinking water supplies for more than 200,000 people in the Waco area. Water quality testing found high levels of nutrients in the North Bosque that have contributed to excessive growth of algae and other aquatic plants in the river. This TMDL project addresses the elevated levels of phosphorus (the limiting nutrient in the watershed).

The project is now considering refinement of the models used to simulate conditions in the Bosque River. An advisory group has been formed to advise the TCEQ and its contractors on this aspect of the project.
