The Martha's Vineyard Watershed drains approximately 89 square miles, encompasses all six towns on the Island of Martha's Vineyard, and includes 13 named streams, 42 lakes, approximately 125 miles of coastline, and an astounding 8,777 acres of estuaries.
It has become a famous vacation spot, attracting thousands of tourists throughout the year. Martha's Vineyard's year-round population of approximately 14,000 people grows to approximately 100,000 during the summer. The Island also has approximately 25,000 visitors per day during the summer months. In 1999, Dukes County (Martha's Vineyard) was the third fastest growing county in Massachusetts (behind Barnstable and the Island of Nantucket).
Martha's Vineyard provides a natural sanctuary for 90 rare and endangered species and ecosystems, including maritime sandplain grasslands, which have limited worldwide distribution and are considered a globally imperiled natural community. Martha's Vineyard is considered a sole-source aquifer because all the drinking water for the island is supplied by a groundwater aquifer, which is recharged solely by precipitation.
