Farrington Lake is a scenic freshwater reservoir in Middlesex County, New Jersey near Milltown, New Jersey. Created by a dam on the Lawrence Brook, a tributary of the Raritan River, the lake is in fact a widened section of the Lawrence Brook. Its main tributaries are the Ireland Brook, the Beaverdam Brook, and the Oakeys Brook. The lake is named after Edward Farrington, mayor of New Brunswick, New Jersey, in 1915–1918, who envisioned the construction of the dam to supply water to his city. Mayor Farrington died while in office, in 1918.
