Warragamba spill peak cut by lower catchment rainfall

Warragamba spill peak cut by lower catchment rainfall

08 April 2022

Warragamba Dam’s spill rate is falling after it peaked at 2am overnight at 117 gigalitres per day (GL/day) - well down on today’s predicted peak.

Other major dams spilling in key areas – including Nepean and Woronora – also peaked overnight and spill volumes are continuing to fall.

The Warragamba catchment received rainfall totals well below the overnight forecast, resulting in reduced inflows and no likelihood of the larger peak spill previously predicted for this afternoon.

This morning (6am) Warragamba dam was spilling at a reduced rate of 92 GL/day and falling, with inflows occurring at a rate of 96 GL/day.

WaterNSW will work closely with the Bureau of Meteorology to monitor weather forecasts for key catchments and inflow projections.

WaterNSW is monitoring any impacts on the quality of water in Sydney’s dam storages as a result of the inflows and working with Sydney Water and NSW Health to manage supply.
