What We Do

Stormpipe on Shoreline

A crucial role of the Massachusetts Bays Program is to track and document the condition of the estuaries and embayments of Massachusetts and Cape Cod Bays. With the help of many collaborators and contributors, we report on the condition of water quality within the Bays, the health of important estuarine and coastal habitats, and trends in human use and development along the Massachusetts Bays coastline. 

Topics include changes in the water chemistry of Boston Harbor due to improved wastewater management (Question 2), causes of Harmful Algal Blooms (Question 3), trends in eelgrass beds throughout Massachusetts Bay (Question 8), and acreage of land protected since our last State of the Bays Report (Question 16), to name just a few.

In 2004, the Program issued its first State of the Bays Report pdf format of State of the Bays 2004
file size 2MB , summarizing the status of 17 indicators of the health of our planning area. In the December 2010 State of the Bays Report pdf format of State of the Bays 2010
file size 14MB , we track the current status and recent trends of many of the same indicators and several that have been added since our last report.
