Shallow water in marked channel

When

Advice

Vessel operators are advised that the depth of water has been decreased due to the ongoing movement of sand in the vicinity of Little Box Head to Lobster Beach, Brisbane Water potentially restricting navigation to some vessels.

Navigation warning

Vessel operators are advised to exercise extreme caution when navigating in the vicinity of the area due to the reduction of water depths in the marked channel. Additional navigation safety marks have been placed in this location to advise deepest channel areas.

Directions

Transport for NSW advises: 

• Vessel operators are advised that the marked channel from Little Box Head to Lobster Beach remains a navigable channel with areas of shallow water which may not be suitable for navigation by vessels with a deeper draft.
• All vessel operators are advised that large vessels and deeper draft vessels navigating in the area from Little Box Head to Lobster Beach may be constrained by their draft, therefore requiring right of way in the navigable channel.
• The marked channel in the vicinity of Lobster Beach is a 4 knot zone speed restriction zone. Vessels operators are advised to navigate with caution at reduced speed in the 4 knot speed restriction zone.
• All vessel operators are to provide all due care when transiting this stretch of the waterway until further notice.
