The following is information about each of the fifteen main coastal pond systems on Martha's Vineyard: the overall watershed, the pond itself, its water quality, the status of the Massachusetts Estuaries Project (MEP), and the status of implementation of improvement measures. (As MEP studies are completed, the MVC prepares four-page highlights, which should be read in conjunction with Highlights of the MEP: Nitrogen Loading in Coastal Ponds, which explains the basic concepts.)
