Dredging we undertakeĭue to the natural movement of material, it is not always cost effective or environmentally responsible to dredge in all locations that may be desired by boat owners. This is particularly the case where sediments are contaminated. In other locations an environmentally responsible method of disposing of dredged material needs to be found for each dredging project. In some locations sediment is clean sand that can be used for land fill or nourishing beaches. The process of dredging involves using machinery to gather up bottom sediments such as sand, silt or mud. This sometimes results in shoaling that poses difficulties for some boat owners.ĭredging is an excavation activity that artificially deepens or widens waterways to improve navigational safety or to maintain particular design depths. Waterways are often a complex network of naturally shallow areas and deeper channels with many of these constantly changing in response to natural processes. Potential new dredging projects are identified through proposals received from councils and port authorities, information provided by boating organisations and individual boat users, plus an extensive ongoing program of hydrographic surveys to monitor changes in channel depths. With the continuing growth in recreational boating, the expectation for dredging is always high. We maintain channels for recreational boating in high-use waterways for access to facilities owned by the department when it is financially and environmentally feasible to do so.
