The Environmental Protection Agency (EPA), in 1986, initiated a water quality assessment of West Point Lake on the Chattahoochee River near LaGrange, Georgia. The EPA Region IV Environmental Services Division (ESD) evaluated the existing water quality condition of West Point Lake and the effects of the upstream nutrient loads on the system. Based on July, August, and September 1986 water quality data collected, water quality problems such as high levels of nutrients and high levels of chlorophylla were observed (EPA 1987). Additional data were collected in 1987, through a joint Georgia Department of Natural Resources (GaDNR) and EPA study (GaDNR 1987). These data confirmed the existing water quality problems. Evaluation of the 1980 to 1989 nutrient and chlorophylla data shows these values have increased over this period and would continue to do so unless increases in upstream nutrient loadings are curtailed.
