Preparing for forecast poor weather

With significant rainfall forecast over the next two days and large swells predicted from Tuesday through to Friday, Council has mobilised crews and machinery to reduce the risk of flooding.

We have prepared a channel at the Narrabeen Lagoon entrance to enable crews to open the lagoon if it reaches the level where the entrance is most likely to remain open. To understand how Council manages the lagoon please watch the video explainer.

We have also prepared an entrance channel at Manly Lagoon. Normal rainfall can escape via the low flow pipes, however if the rainfall is more intense and the levels rise to the required level, Council will mechanically open the Lagoon entrance at Queenscliff beach.

Dee Why and Curl Curl lagoon entrances have also been inspected and pilot channels have been prepared in anticipation of both lagoons reaching breakout trigger levels in the coming days.

Council is inspecting and clearing known stormwater blockage hotspots and monitoring known coastal erosion risk areas. 

We are also paying particular attention to our stormwater assets such as Ramsey Street and other outlets to the ocean at Ivan Hoe Park and North Harbour Reserve gross pollutant trap.

Council will continue to monitor forecasts, water levels and stormwater assets closely and have crews on standby to take any additional required action.
