PortsToronto Starts Annual Dredging of the Don River

PortsToronto is about to begin annual dredging project that will remove up to 40,000 cubic meters of debris and sediment from the mouth of the Don River.

Each year, thousands of tons of sediment build up where the Don River empties into the Keating Channel which, if not removed, could cause the river to backup and flood, or, in some cases, debris to spill into Toronto’s Harbor.

PortsToronto, in conjunction with the Toronto Region and Conservation Authority (TRCA), provides annual dredging of the waterway which helps to maintain a river depth, allowing for the smooth flow of water and ice through the Keating Channel.

The dredging process involves scooping large amounts of material from the bottom of the channel using a clam bucket. Once removed from the channel bed, the muddy mixture of debris and sediment will be transported by barge to the Leslie Street Spit (the Spit) for proper containment.

The current dredging is set to begin later today, September 23, and will continue through to the middle of November.
