Here Are Updates On Peterborough Earth Dams

Parks Canada has been rehabilitating the earth dams along the Trent-Severn Waterway in Peterborough. Earth dams are vital for flood mitigation and therefore the safety of visitors, residents and property. These investments will further reduce the risk of flood damage along the canal corridor.

After beginning work in the fall of 2015, it has reached the active heavy construction phase this past spring. Below are updates for specific areas.

THE EARTH DAM AT THOMPSONS BAY IN NORTH PETERBOROUGH

This was the first to reach the construction phase and is now nearing the final stages of work. At this location, all vegetation has been removed, the dam strengthened, and the new earthen material compacted into place. The water facing side of the dam has also been repaired and armoured with rock. The final stages of work will see additional top soil added to the berm followed by a re-greening of the surface using a specially developed seed mix of tall grasses. The work is slated to completed by mid- to late-September.

THE HURDONS EARTH DAM & CURTIS CREEK EARTH DAMS

At these locations along the western shoreline north of Parkhill Road and the eastern and western shorelines south of Parkhill Road, the contractor continues to remove vegetation—particularly tree roots—which posed a threat to the long term reliability of the earth dams. Work along the dry surfaces will continue late into the fall with the in water work occurring after the close of the Trent-Severn Waterway’s navigation season.

PETERBOROUGH EARTH DAMS

Large sections of Trent-Severn Waterway shoreline within the City of Peterborough are engineered structures designed to keep water inside the canal and out of adjoining neighbourhoods. In 2015, Parks Canada announced a project to rehabilitate more than 2 km of these earth dams.

The major repairs to the Earth dams throughout Peterborough began in November 2015 and are estimated to continue until Summer 2019. In order to rehabilitate and strengthen these dams, washouts will be repaired, dam height will be increased where necessary and vegetation will be removed. 

HOW THE PUBLIC CAN ENJOY THE EARTH DAMS WHEN COMPLETE

Following the completion of repairs, the dams will be green-scaped with beneficial plants like milkweed, wildflowers and tall grasses. Recognizing the part the earth dams play as public green spaces, Parks Canada will be formalizing the walking trails at these sites at the end of the project so that they can be better enjoyed by members of the community.
