Dredging program has commenced in the Main Channel North at Cabbage Tree Point.
Approximately 15,700m³ of material will be dredged from the channel to a designed depth of -2.7m LAT.
The sand will be placed on the foreshore at Cabbage Tree Point, adjacent to the channel.
The Cabbage Tree Point dredge site is located on the Main Channel North, north of Jacobs Well, and south of the Tabby Tabby Channel confluence, adjacent to the Cabbage Tree Point boat ramp. Immediately adjacent to the dredge area, land is developed for residential uses, and many of the lots with water frontage have private jetties extending into deeper waters to allow low tide use.
The dredge area begins approximately 15m north of the Cabbage Tree public boat ramp, extending southwards for approximately 500m.
The cutter suction dredge Nu Discovery will be used for this project.
The works are required to maintain safe navigable depth within the Main Channel North, which has been impacted by significant sand deposition and shoaling.
This channel forms the primary movement channel for vessels travelling between the northern and southern areas of Moreton Bay, and it is therefore important to maintain navigable depths under all tidal conditions.
Due to build-up of sand, water depths within the defined navigation channel at low tide are reduced to under one meter in some areas.
Beach nourishment for recreational amenity is the selected dredge material management option to improve the amenity of the foreshore and provide additional protection to land which has been subject to steady erosion.
