Dredging Operations Continue at Harbour this Fall
Cobourg, ON (September 24, 2026) – The Town of Cobourg would like to advise residents that dredging operations in the Cobourg Harbour will be continuing this week and into the fall season.
About Dredging
With water depths getting low, dredging is needed for safe passage for the Coast Guard and other vessels. Dredging begins at the entry of the harbour to ensure safe access for the Coast Guard. Additional dredging is conducted as required to maintain water depth. Staff will make every effort to minimize disruptions and work around activities taking place along the waterfront.
Mechanical dredging involves removing accumulated sand and silt, which contributes to shallow water levels and hinders boat anchoring and navigation. Maintaining proper depths in the harbour ensures continued accessibility and functionality for boaters and recreational users. This is part of the Town's ongoing commitment to maintaining the harbour’s functionality.
Dewatering Sand on the Beach
Residents visiting the waterfront will notice piles of sand and holes in the beach. These are a result of dredging operations, allowing water to percolate out of the sand before it is trucked off-site. Fencing is installed to ensure public safety during this time.
Third Street, Hibernia, and Marissa Lane Residents
Residents along Third Street, Hibernia and Marissa Lane will notice the presence of the dredge supply trailer parked in the Marina parking lot. The trailer will be on-site when dredge supplies are needed on site. When not in use, the trailer will be moved off-site.

Since 2009, the Town of Cobourg has owned and operated the Marie Dressler Dredge as a public service. In addition to servicing the harbour Cobourg Harbour, the Town operates the dredge as a business venture, renting out services to maintain neighbouring municipalities harbours and waterways.
