(Cobourg, ON) April 19, 2018– The Town of Cobourg would like to advise citizens that the Cobourg Marina will begin annual spring dredging maintenance at the entrance of the harbour, boat launch and the inner harbour area as early as next week and is expected to continue for approximately four weeks.
Each year a significant amount of sediment is carried along the north shore of Lake Ontario by waves and currents and deposited at the mouth of the harbour and within the harbour itself. This sediment can accumulate in amounts that make safe navigation an issue for recreational boats as well as the coast guard vessel which is stationed in Cobourg Harbour each summer. In order to keep the harbour safe for navigation the Town of Cobourg must perform annual maintenance dredging.
Dredging is an excavation activity where sediments are gathered up from the bottom of the lake and deposited at different locations. This year the sediment will be re-deposited onto the beach, a technique used to proactively keep our waterline back and potential sand erosion to a minimum.
