Wyangala Dam Flow Increase - Airspace Operation
This is a Wyangala Dam flow increase notification.
Releases are planned to increase from 3,300 Megalitres per day to 10,000 Megalitres per day at 5:00 PM on Monday 29 August 2016.
This is continuation of the airspace releases started on Tuesday 2 August by WaterNSW, the State's river system operator.
These airspace operations involve releasing the ongoing inflows to maintain storage capacity to capture any future significant inflows caused by more rain in the dam's saturated catchment.
Under the operating rules for Wyangala Dam, airspace releases:
• must factor in downstream conditions so the river remains beneath minor flood level at Forbes and Jemalong, and;
• may only be conducted where catchment conditions and weather forecasts provide a high degree of certainly that the storage will be at full supply level for the beginning of the irrigation season in October.
Downstream landholders have been notified, while users registered with WaterNSW's Early Warning Network (EWN) will receive automated updates in advance of changes to the release pattern.
While WaterNSW will manage release volumes to remain below minor flood level, downstream landholders should exercise caution with regard to stock and equipment.
