SBEP has been a focal point for the local government agencies and assists them in their efforts to protect water quality in the estuarine waters of the area. To this end, SBEP has provided a forum for the establishment of critical environmental endpoints to assure increasingly difficult funding opportunities are being effectively applied. II. Objectives The primary objectives of this project are: to develop a data base of water quality and nutrient loads for each of the major bay segments; h To define the chlorophyll a thresholds that meet light attenuation and seagrass targets in each bay segment; to define the quantitative relationships between nutrient concentrations or loading and chlorophyll a concentrations in each bay segment; and to estimate the numeric nutrient criteria, i.e., the nutrient concentrations or loading consistent with the chlorophyll a thresholds, for each bay segment.
