Adequacy of Ontario's Water Resources

CIM Bulletin, 1967

A. K. Watt Assistant General Manager, Ontario Water Resources Commission.

The availability of fresh water to meet present and future needs in Ontario is of concern to an increasing number of people. Rain and snow are the source of our potable water and provide, on the average, some 180,- 000 billion gallons of water annually. This amount is reduced to 94 billion gallons a day as a result of the evaporation and transpiration of water and our inability to construct the necessary reservoirs for capturing surplus stream flow.
