    Abstract

    The Vollenweider-Organization for Economic Cooperation and Development (OECD) models are statistical relationships that describe the functioning of aquatic ecosystems in the use of aquatic plant nutrients (nitrogen and phosphorus) for the production of planktonic algae. These models were developed on the basis of data from several hundred dodies of water throughout the world; those discussed herein define the relationships between normalized phosphorus loads to lakes and reservoirs and the planktonic algal chlorophyll, algal productivity, algal-related water clarity, hypolimnetic oxygen depletion rate, and fish yield. Guidance is provided on the use of these relationships for assessing the overall functioning of an aquatic ecosystem.
