The Gypsy (previously known as the Witch and the Wren) is a historic catboat whose home is in Wareham, Massachusetts. She was designed and built in 1900 by Bowdoin B. Crowninshield, as one of four identical sailing vessels, and was designated Crowninshield #149. Her design was influenced by the "Seawanhaka Rule", instituted at the Seawanhaka Corinthian Yacht Club to govern important characteristics of racing boats. She has a spoon bow, low freeboard, and long overhangs rising out of the water fore and aft. Her hull is made of white cedar on an oaken frame, although the top levels have been replaced with cypress.The boat design was commissioned by Charles Henry Davis, who received the Hun, the first of the four boats built. The Witch was the second in the series, and was delivered to Osborne Howes II. (In-laws of Howes purchased the other two.) The Witch was first berthed at the summer house of the Howeses in Yarmouth, Massachusetts, which was called "The Witch House", and used by the family in informal races. She was sold by Howes in 1926, and came into the hands of Edward Barus, who sailed her in the Osterville area. After she was damaged in the New England Hurricane of 1938, she was rerigged from a gaff rig to a Marconi rig. In 1949 the boat, now named Wren, was purchased by Marjorie O'Brien, its present owner, who gave the boat its present name.The boat was listed on the National Register of Historic Places in 2008. It is normally berthed at a dock at 35 Lydia Island Road, and may be seen sailing in Onset Bay.

The Agawam River is a 10.7-mile-long (17.2 km) stream in southeastern Massachusetts, USA, that is part of the Wareham River estuary watershed. The Agawam River is named in honor of the peaceful Native Americans that helped the Massachusetts Bay Colony establish its first Connecticut River Valley settlement at Springfield, Massachusetts in 1636, and helped it to flourish while many of the Connecticut Colony settlements south of Springfield were attacked or destroyed by more war-like Native American tribes. The Agawam River originates at Halfway Pond, east of the Myles Standish State Forest in Plymouth, flows southwest through Glen Charlie Pond and East Wareham, and drains into the Wareham River near the center of Wareham. As the estuary's major contributor of nutrients and fresh water, the Agawam was one of the most important herring rivers in Massachusetts. Its herring runs have been operated by European settlers since 1632 and were officially established as a managed run in 1832. Even today, it remains one of the few managed herring runs in Massachusetts, although few fish reach the river's spawning and nursery habitat. It includes 570 acres (2.3 km2) of water bodies that could serve as habitat to alewife, blueback herring, and American shad. Approximately 36% of this habitat is in Halfway Pond. Fishway retrofit projects aim to restore river herring population to historic levels, perhaps as many as 100,000+ fish annually. The Agawam River receives discharges from the Wareham Sewage Treatment plant, which discharges 0.76 million US gallons (2,900 m3) per day of nitrogen-rich sewage effluent.
