Narrabeen Lagoon Entrance Blocked Again
Narrabeen lagoon entrance is blocked again, after recent storm swells, and Council spending $1.5. million on moving the sand south to Collaroy for weeks.
Council announced on Tuesday, 12 September 2023 work to clear Narrabeen Lagoon entrance to reduce the risk of flooding to local homes and businesses.
''Council contractors will excavate more than 20,000 cubic metres (40,000 tonnes) of sand – equivalent to the weight of 100 jumbo jets – to the east and west of Ocean Street Bridge.'' it was stated
The sand is to be deposited at Collaroy-Narrabeen Beach between Goodwin and Stuart Streets.
Works were expected to start in the coming weeks, although the above photo shows they were commenced immediately, and were completed in time for the Summer school holidays, which commenced on December 19 2023. This means the lagoon entrance was open for around 6.5 weeks prior to the big seas which moved so much sand over the past few days of weather conditions as the tail end of Cyclone Kirrily moved south.
After impacting Queensland, ex-Tropical Cyclone Kirrily crossed the border into western NSW on Monday afternoon, February 5, bringing heavy rainfall and flash flooding to inland communities, before reaching Sydney early the next day bringing 21mm of rain and localised flash flooding, along with strong winds.
This had preceded by swell set to peak at 4 to 4.5 metres in Sydney over the weekend of February 3-4.
However, at high tide about 6 inches of water still goes over the top of the entrance and into the lagoon. Joe Mills' (Turimetta Moods) sent in pictures this week of Pelicans standing in the shallow overflow at high tide - see below.
Joe said; ''They are waiting (with the Cormorants and Seagulls as well) for the small fish brought in by the waves.''
So - good for some residents of the lagoon.
