 A jetty and aggregate processing facility was constructed on the west side of the reservoir just north of the intake.The emergency drawdown rate (the rate at which the water level in the reservoir can be reduced) was about 0.25 metres/day.Inspections in 2005-07 identified that this was inadequate, and proposed that the drawdown should be 0.75 m/d as defined in the provisions of the "Reservoirs Act 1975".
