The dam, constructed in the 1800's with rebuilding and repairs through the late 19th century, diverted the Cranbury Brook in order to supply power to the local grist and saw mills.

Local sewer construction in the 1977 unearthed and partially destroyed portions of the original structure before archaeologists halted the work and revealed portions of a well-preserved crib dam.
