Abstract Data collected by the National Eutrophication Survey (NES) team for 418 eastern lakes were utilized to determine correlations between chlorophyll alpha, an indicator of lake productivity, and nutrient and other water quality parameters. High linear correlations were determined between total phosphorus and mean chlorophyll alpha levels, especially in lakes with retention times of greater than 14 days. These basic relationships were compared for populations of lakes subdivided on the bases of stratification, vegetation dominance and fishery type. Relationships between lake 'problems' and nutrient or other water quality parameters were established by comparing historical and observational data of general lake conditions with physical, chemical and biological values obtained from NES sample analyses. The distributions of lakes with algal blooms, aquatic macrophyte problems, low dissolved oxygen concentrations, and/or fishkills are presented as functions of mean total phosphorus and chlorophyll alpha concentrations.
