House of Assembly Fifty-Fourth Parliament, Second Session (54-2) 54 2 Parliament of South Australia House of Assembly published Answers to Questions Port MacDonnell Harbour Port MacDonnell Harbour In reply to Mr BELL House of Assembly Mount Gambier Port MacDonnell Harbour In reply to Mr BELL (Mount Gambier) (11 May 2021). The Hon. C.L. WINGARD House of Assembly Gibson Minister for Infrastructure and Transport Minister for Recreation Port MacDonnell Harbour The Hon. C.L. WINGARD (Gibson—Minister for Infrastructure and Transport, Minister for Recreation, Sport and Racing): I have been advised: The Department for Infrastructure and Transport (DIT) undertakes regular hydrographic surveys of the Port MacDonnell boat haven to monitor sand and wrack material (drifting dead seagrass and marine algae) movement. These surveys have identified that a significant amount of wrack material has accumulated in the boat haven in the vicinity of the boat ramp, wharf and within the marked channel. Sand has also accumulated in the area near the end of the breakwater. DIT intends to dredge these areas. DIT is working with the Environment Protection Authority to identify suitable dredging methodologies to enable the dredging program to commence. A timeline for the dredging program cannot be developed for the program until this has occurred. To facilitate safe access to the landing area and boat ramp at Port MacDonnell, a safe navigable channel is marked by lit lateral beacons in line with international guidelines. The channel and its depth are also documented on official navigational charts issued by the Australian Hydrographic Office. Like all harbours and waters around the state, the safe operational depth is governed by the rise and fall of the tide and safe under keel clearance is the responsibility of the vessel operator.
