Maryland Coastal Bays Report Card 2009

The aim of this report card is to provide a transparent, timely, and geographically detailed assessment of 2009 Coastal Bays health. Coastal Bays health is defined as the progressof four water quality indicators (TN, TP, Chl a, DO) and two biotic indicators (seagrass, hard clams) toward scientifically derived ecological thresholds or goals. The six indicators are combined into one overarching Coastal Bays Health Index, which is presented as the report card score. Detailed methods are available at The overall score for the Coastal Bays was a C+ in 2009. While the northern bays and western tributaries continue to struggle, there are signs of improvement in some areas. However, the southern bays—historically the more pristine of the Coastal Bays—are showing signs of degradation.
