Abstract A study of the sources and significance of nitrogen and phosphorus compounds to Lake Ray Hubbard located near Dallas, Texas has been completed. This water supply reservoir was experiencing excessive growths of algae which were causing taste and odor problems in the finished drinking water. Phosphorus was found to control algal growth in most parts of Lake Ray Hubbard; about 50 percent of the P load was found to be from domestic wastewater treatment plant effluents. The main body of this lake was found to obey the P load-response relationships developed in the US OECD eutrophication modeling study. Application of this model to Lake Ray Hubbard showed that the initiation of phosphorus removal from domestic wastewaters by chemical treatment would result in this waterbody maintaining its current water quality.
