Built in an old council quarry it was originally used to supply water to Liverpool. 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.
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).
