The main objective of this work is to provide resource managers and estuarine scientists with a clearer perspective on a key management question: After three decades of restoration, has progress been made in reducing nitrogen, phosphorus, and sediment exports from the Bay watershed? This synthesis leverages available monitoring, modeling, and research to quantify long-term trends in the true-condition loads from the River Input Monitoring (RIM) tributaries as well as the various major sources from the below-RIM watershed. In addition, this work provide a synthesis of literature on estuarine response to changes in nutrient loads and emerging challenges to load reductions.
