The uncontrolled spillway was capable of discharging. At that time, the top water level of the dam was above sea level and the reservoir had a capacity of 3856ML. A subsequent review in October 2006, using more accurate mapping methods, resulted in capacity being re-estimated downwards from the previous estimate of 4700ML. Additional galleries and drains were constructed between 1984 and 1986. In order to supply the city with potable water, water from the reservoir was pumped to Mount Stromlo, and from there the water flowed by gravity to fill the city's reservoirs.
