Narrabeen Lake Sand Dredging

[mrmoshe]

Sand dredging in Narrabeen Lake is due to begin this week.

43,000 cubic metres of sand is to be removed either side of the Ocean St. bridge.

There were some worries of it impacting on the sea grasses in the area, but they seem

to have taken that into account.

Here is the story from today's Manly Daily:

Project won't harm seagrass

EXCAVATION of sand at the mouth of Narrabeen Lagoon is expected to start this week, with about 43,000cu m to be removed and used to nourish the Collaroy-Narrabeen beachfront.

The contractor, Kingston Civil Constructions, will drape silk curtains to prevent turbid water affecting nearby seagrass beds.

The project is being jointly funded by Warringah Council, Pittwater Council and the State Natural Resources Department, which has contributed $500,000 towards the project.

Work is expected to be completed by December.

The sand will be removed from the lagoon entrance, to the east and west of the Ocean St bridge, and operations will be run from the Birdwood Park car park.

There have been seven major clearance operations at the lagoon entrance since 1975, with the most recent in 2002, when about 40,000cu m of sand was removed.

A council spokesman said the removal of sand from the lagoon's entrance is an integral part of the management of the lagoon.

Warringah Council customer and community services director Gary Thomson said no seagrass beds would be affected by the sand clearance.

``Pollution control devices will be put in place during the dredging, including silk curtains where the machinery is operating.''
