The aim of this report card is to provide a transparent, timely, and geographically detailed assessment of 2013 Coastal Bays health. Coastal Bays health is defined as the progress of four water quality indicators (total nitrogen, total phosphorus, chlorophyll a, dissolved oxygen) and two biotic indicators (seagrass, hard clams) toward scientifically derived ecological thresholds or goals.

This project analyzed existing aquatic sediments, plants, and animals collected throughout the watershed to pinpoint key sources of nitrogen. As submerged aquatic vegetation has disappeared in regions heavily impacted by land-use activities, macroalgae and oysters were deployed and incubated in situ to help trace the origin of nitrogen inputs by identifying, delineating and mapping the relative influence of the varied urban and agricultural land uses in the watershed.

In 2013, Baltimore's streams, river and Harbor scored between 51% and 57%. While this is a failing score, it is an improvement over the 2012 scores, which ranged from 40% to 42%. These modest improvements show that we are headed in the right direction, but there is still a lot of work to be done. Without significant infrastructure repair and environment restoration, areas dominated by urban and suburban development will continue to have poor water quality.

This report card provides a transparent, timely, and geographically detailed assessment of Chesapeake Bay. In 2013, the report card includes five water quality indicators and two biotic indicators. In 2013, the overall grade for Chesapeake Bay is a 45%, a C. This means the Bay is in moderate health. Fisheries indicators as well as trajectories of reporting region health are also presented. For further details, visit the Report Card website.

Mills Creek is a small tributary to Sandusky Bay on the south-central shore of Lake Erie. The Mills Creek watershed is largely developed by a combination of urban and agricultural land uses. Mills Creek is also part of a Karst geological region, which is characterized by a series of sinkholes and underground rivers flowing through cracks and cavities in the limestone bedrock.
