Watershed report cards are powerful tools to describe ecosystem status, increase public awareness, and inform and influence decision makers to improve the health of a watershed. This is the first Upper Rio Grande Report Card. It is the collective effort of dozens of stakeholders throughout the Upper Rio Grande watershed. Indicators in the report card were selected to assess the health of four different values in the watershed:

Coastal Bays health is defined as the progress of four water quality indicators (nitrogen, phosphorus, chlorophyll a, dissolved oxygen) and two biotic indicators (seagrass, hard clam) toward scientifically derived ecological thresholds or goals. The Coastal Bays had an overall score of C+, a slight improvement from the previous year. Improved total phosphorus scores contributed to the slightly higher overall health of the bays.

Reporting on the State of the Maryland Coastal Bays is an opportunity to step back and reflect on the status and trends of key environmental features in this iconic region. The theme of this State of the Coastal Bays is building ecological resilience in the region. This focus on resilience is due to the convergence of several factors:

Every five years, The Maryland Coastal Bays Program publishes its State of the Bays Report, accompanied by the annual Maryland Coastal Bays Report Card. The theme of the 2022 State of the Coastal Bays is building ecological resilience in the region. This focus on resilience is due to the convergence of several factors:

Many coastal ecosystems suffer from eutrophication, algal blooms, and dead zones due to excessive anthropogenic inputs of nitrogen (N) and phosphorus (P). This has led to regional restoration efforts that focus on managing watershed loads of N and P. In Chesapeake Bay, the largest estuary in the United States, dual nutrient reductions of N and P have been pursued since the 1980s.
