Manalapan Brook is a tributary of the South River in Monmouth and Middlesex counties, New Jersey in the United States.

Course

The Manalapan Brook's source is at 40.19056°N, -74.3975°W in western Monmouth County, a few miles south of Monmouth Battlefield State Park, and roughly adjacent to the headwaters of the Manasquan River, Matchaponix Brook and Millstone River systems in the much larger Raritan Basin. This long brook flows generally north, traversing, along with its tributaries, much of Monmouth and Middlesex Counties. Its drainage basin, the Manalapan Brook watershed, is a 43 sqmi area, includes the municipalities of Millstone Township, Freehold Township, Manalapan Township, Englishtown, Monroe Township, Jamesburg, Helmetta, Spotswood, South Brunswick Township, and East Brunswick Township. There are man-made lakes created by dames alongside the course of the brook, including: Bulk's Lake (near the Charleston Springs Golf Course in Millstone), Millhurst Pond (Manalapan), Lake Manalapan (Jamesburg), Helmetta Pond (Helmetta), and Devoe Lake (Spotswood). After crossing the dammed section named Lake Manalapan in Jamesburg, Manalapan Brook continues north along CR 615 (Main Street) before flowing into Devoe Lake in Spotswood. The flow then merges with the Matchaponix Brook forming the South River at 40.3925°N, -74.38278°W along the border of Spotswood and Old Bridge Township.

History

Manalapan in the Unami Lenape dialect more correctly corresponds to Man- "tilt/slant" Alapan- "Sunny weather"- combined would describe sun rays through Manalapan's forests and fields, which were maintained by the Lenape by a combination of localized syntropic farming and hunter-gathering lifestyle.
