Great Bay National Estuarine Research Reserve

The Great Bay National Estuarine Research Reserve encompasses a diversity of land and water areas around Great Bay, an estuary in southeastern New Hampshire. Protected lands cover 10235 acre, including approximately 7300 acre of open water and wetlands that include salt marshes, rocky shores, bluffs, woodlands, open fields, and riverine systems and tidal waters.

Great Bay has a rich cultural history and was the first major commercial waterway developed by the early settlers.

The National Estuarine Research Reserve System (NERRS) is a nationwide network of state-owned and -managed coastal protected areas. These are designated and supported by the National Oceanic and Atmospheric Administration (NOAA) under the United States Department of Commerce.

The New Hampshire Fish and Game Department under the Marine Fisheries Division manages the Great Bay NERR. Designated in 1989, the reserve's primary purpose is to promote the wise use and management of the Great Bay estuary.
