Northern Beaches Council is preparing an entrance channel at Narrabeen Lagoon this morning in preparation for heavy rainfall over the coming days. Heavy machinery is operating at the entrance to today to dig a channel to help open the lagoon once the level rises.

The lagoon is normally opened when levels are between 1m and 1.3m above sea level. The lagoon is now at 0.8m above sea level and approximately 50mm of rain is forecast over the next two days. Council staff will monitor the rainfall and lagoon conditions over the coming days and will open the lagoon when the water levels hit these trigger levels, and tides and ocean conditions allow.

Timing the lagoon opening in large weather events is challenging. To better understand how Council manages the opening of the lagoon, watch this video.
