Built in an old council quarry it was originally used to supply water to Liverpool.[2] Various offtakes were constructed along the Sydney Water Supply Upper Canal for local district supply. It was also used to drain water from the nearby Upper Canal during maintenance.[3][4]
In 1901 another reservoir at Mount Misery, Heckenberg was constructed between this dam and Liverpool.
In 1933 the dam was cleaned out and the wall upgraded to increase its volume from 4 to 37 million imperial gallons (18 to 168 ML).
