UMCES researchers worked with local Riverkeeper organizations to produce river-specific report cards for the Chester, Patuxent, and Severn Rivers. These reports, funded by the Chesapeake Bay Trust and supplemented by data collected by citizen scientists, are designed to provide the organizations with a new set of tools to better track local ecosystem health of their waterways and report them to their communities. The Chester River estuary received a D, the Patuxent River a D-, and the Severn River a C-.
