Dundee Beach boat ramp

In 2018, the Department of Infrastructure, Planning and Logistics (DIPL) appointed Cardno to undertake a study which looked at where the sediment is coming from, how to reduce build up on the Dundee Beach boat ramp and possible solutions.

The study considered:

  • the effect of excavating in various locations to reduce sediment build up on the ramp
  • possible upgrades to the existing groyne to address its porous nature and/or extend it
  • possible additional infrastructure, such as a new groyne to the south of the boat ramp.

The study found that there is no ‘silver bullet’.

There are a number causes of sediment build up on the boat ramp and in the boating channel.

Some of these can be addressed such as sediment travelling through the groyne to settle on the boat ramp. Others, such as suspended sedimentation (the sediment mixed in with the water) cannot be dealt with at any feasible cost, which the study found is the reason for most of the sediment build up on the ramp.

Working group

In 2020, the Northern Territory (NT) Government formed a working group to:

  • consider findings of a sediment-movement study at Dundee Beach boat ramp and
  • develop short, medium and long term options for Government’s consideration.

The working group includes representatives from:

  • the NT Government (including NT Fisheries and DIPL)
  • AFANT and
  • NT Guided Fishers Association.

The working group has a number of short-term remediations that could be adopted while a longer term infrastructure works are being considered to improve the marine facilities at Dundee.

This includes a short term proposal for a performance-based maintenance contract, which will allow for innovation and cost efficiencies to be achieved in the sand removal process.

Given the sedimentation issues, the working group has acknowledged that the ramp will be accessible in tides above 2.8 metres. This level will ensure safety for users, particularly those who are inexperienced.

Ramp users should always check current weather and marine conditions prior to launching and plan accordingly.

Upgrades

The NT Government will be undertaking works to improve functionality of the Dundee boat ramp, including upgrades of the:

  • groyne
  • provision of a footpath
  • construction of a pontoon to allow for safer loading and unloading of recreational vessels.

A tender for the detailed design will be released in early 2022, with the tender for construction expected to be released late 2022.
