​​​The Pretty River Dyke

In the 1970s, the Pretty River Dyke was built to reduce the risk of flooding in the urban areas of Collingwood.

It is designed to contain the floodwaters from the​ Provincial Regulatory Storm Event — a storm so extreme that the likelihood of it happening is less than 1% chance in any given year. Although these events are rare, the risk to property damage and possible loss of life is high which is why the dyke must be maintained.

This 2 km flood control structure starts at the southwest intersection of Peel Street and Lynden Street, passing the old CN Rail bridge (now the Siding Trail), then Hume Street and the Pretty River Parkway before ending at Oliver Crescent near the shore of Nottawasaga Bay. 

Maintenance Proje​ct

The Pretty River Dyke was designed to help keep the downtown areas of Collingwood safe from flooding.

In order to make sure it functions properly, some of the vegetation growing along the banks of the dyke must be removed from time to time.

Climate Change may increase the likelihood of more intense storms over time, putting pressure on the Pretty River Dyke infrastructure.
