This report card provides a transparent, timely, and geographically detailed assessment of Chesapeake Bay and its Watershed. Since 2016, UMCES has engaged stakeholders throughout the watershed to transform the report card into an evaluation of the Chesapeake Watershed health. Watershed health includes traditional ecological indicators, but also economic and societal indicators. This is the third year the watershed has been scored, and four new economic indicators have been added.
