Corrections to obvious typographical and spelling errors have been made. Corrections to factual errors, updates or comments on the information are either enclosed in [square brackets], or will be clearly indicated as updated material. Since most of the surveys were conducted in the late 1970ā€™s and early 1980ā€™s, much of the information reflects that time period.

South Haven is approximately 5 square miles in area. It is bounded on the east by Carman's River; on the west by Old Stump/Yaphank road; on the north by Southaven Park; and on the south also by the Carman's River. Settlers first came in the eighteenth century to this fertile farm land which rests on an important river. The Montauk Highway runs through the middle of Southaven. Part of it has become the Southaven Park, owned by Suffolk County.


Southaven was first settled in the early 1700s. It is one of the earliest settlements on the south shore of Long Island, due to its location on the river. It was first known as "the South" and Fireplace, and the families came here from the settlements at Setauket. The Presbyterian Church was first built in 1728, the the Southaven Mills (later known as Carman's Mills) were built before 1745. Through the old South Country Road, now called Montauk Highway, and the Sunrise Highway, run through Southaven, it remains largely undeveloped until the present time. A large portion north of the Sunrise Highway is preserved as a park, and a very large tract is preserved in the Wertheim Refuge, south of Montauk Highway.

Supplemental Material

1910: Town Board decides that highway at the going-over bridge crossing the Carmen's River should be straightened. "The Town Board and Superintendent of Highways convened at Patchogue on Monday and proceeded to Southaven to investigate the condition of the highway crossing the bridge at Carman's River. After a thorough examination of the existing conditions, it was the sense of the board that the highway should be straightened to meet the requirements for safety of the increased travel over said highway." The Port Jefferson Echo, Saturday, September 24, 1910.
