Originally a 10-mile (16 km) stream, its course now includes man-made lakes created by dams built in the 19th and 20th centuries: Deans Pond (South Brunswick), Davidsons Mill Pond (South Brunswick), Farrington Lake (South Brunswick, North Brunswick and East Brunswick), Mill Pond (Milltown), and Westons Mill Pond (Milltown, East Brunswick, North Brunswick and New Brunswick). Its lowest section, near the Raritan River, is tidal; it hosts marine wildlife and is regarded as a coastal area.
Though not obvious from the roadways, Lawrence Brook is a wildlife corridor, a bird migration area and a highly sensitive body of water. Power boats, except with an electric motor, are not permitted on the brook.
- This stream was called Piscopeek by the Unami Lenni Lenape Indians. Its current name comes from Mr.Thomas Lawrence, a New York City baker, who acquired its surrounding land in the 17th century. Some historical maps show the spelling Lawrence's Brook.
- In the late 19th and early 20th centuries, Farrington Lake area served as a resort area, with a trolley line running from New Brunswick through Milltown then turning south to eventually end at the State Fair Grounds in Trenton. The lake (named for a mayor of New Brunswick who died during WWI) was formed by a dam built above a lower working dam that powered a snuff mill built in the mid 19th century.
