Dams and Channels

Water Control Infrastructure in the Conservation Halton Watershed

To protect us and reduce the risk of property damage and loss of life due to flooding (a natural hazard), Conservation Halton is responsible for the maintenance and operation of four major dams and 12.5 kilometres of flood control channels. The dams are all designed to control flooding as well as augment stream flows during periods of low water. The flood control channels were constructed to convey and in some cases divert floodwaters away from historically developed flood-prone areas.
