Water quality targets have been adopted by the TBNEP Management and Policy Committees for the four mainstem segments of Tampa Bay. The Tampa Bay Estuary Program has developed a tracking process to determine if water quality targets are being achieved. The process to track the status of chlorophyll-a concentration and light attenuation involves two steps. The first step utilizes a decision framework to evaluate differences in mean annual ambient conditions from the established targets. The second step incorporates the results of the decision framework into a decision matrix leading to possible outcomes dependent upon the magnitude and duration of the events in excess of the target. The objective of this technical memorandum is to compare the annual mean ambient chlorophyll-a concentration and light attenuation for 2003 to the segment-specific targets using the tracking process.
