Overenrichment of surface waters in the United States has been a long-standing problem to the extent that approximately half of the waters reported by the States to be impaired are attributed to excess nutrients and related biological growth. The EPA has established the National Nutrient Criteria Program to address this water quality problem. The surface waters of concern are lakes and reservoirs, streams and rivers, estuaries and coastal marine waters, and wetlands. Criteria representing enrichment conditions of surface waters that are minimally impacted by human developmental activities will be developed for each of the regions of the country. These will then become the basis for States and Tribes of the United States to develop nutrient criteria to protect the designated uses of those waters. This manual is designed to help accomplish this for lakes and reservoirs. Nitrogen and phosphorous are the primary causes of overenrichment and are obvious nutrient criteria variables, but biological response variables are also important in addressing the consequences of overenrichment.
