Pretty River Dike
In the 1970s, the Pretty River Dike 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 dike 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.
