The rainfall forecast for the next 7 days across Seqwater’s dam catchments is for catchment average rainfall of around 60 mm.

The current forecast suggests there is a small chance catchment average rainfall of up to 150 mm may occur.

Based on the current status of the dam catchments and the rainfall forecast, significant run-off into Seqwater’s dams over the next week is unlikely, but posible.

No un-gated dams are currently spilling. Dam level information is updated every 2 hours on the Seqwater website:

Gated dams: Currently Wivenhoe Dam is at 68.5%, Somerset Dam is 74.5% and North Pine Dam is 51.5%. The floodwater storage compartments at Wivenhoe Dam and Somerset Dam are fully available.

On 21 January 2016, temporary full supply levels were enacted for Somerset and Wivenhoe Dams. These equate to storage percentages of approximately 90% for Wivenhoe Dam and 80% for Somerset Dam. This means that once Wivenhoe reaches 90%, gate operations may commence.

Gate operations for flood operations are not expected at Wivenhoe Dam, Somerset Dam or North Pine Dam in the next 7 days and there are no plans for the Flood Operations Centre to be mobilised.
