Originally, it was 65 acres (260,000 m2) in extent, but following repairs to the dam its surface area is now 55 acres (220,000 m2). It was built between 1795 and 1797 by the Grand Junction Canal Company, to control the water levels in the River Colne following the construction of the Grand Junction Canal, and was hand dug by French prisoners of war.
It now forms the centrepiece of the Aldenham Country Park and is used for recreational purposes, including fishing and sailing.
