Learn more about low level water conditions

In the past, periods of dry weather and drought in Ontario were relatively uncommon, usually occurring once every 10- 15 years. Recent studies on changing weather patterns are indicating that low water levels may become more common as the province’s demand for water steadily increases.

A low level water condition is declared when a potential for water supply problems is identified through a lack of rain and streamflow levels. These values are set out by the Province of Ontario in it's Low Water Response Program.

Low water levels and water use restrictions

 Low water conditions range from Level I to Level III, representing progressively more severe water supply shortages and restrictions on water use.

Level One

Declared when a potential water supply issue is identified. By reducing your water use by a minimum of 10% at this critical time we may be able to avoid more serious shortages and lessen the impact of reduced water availability on our environment.

Level Two

Declared when a minor water supply issue is identified with a potential for a major water supply problem. By reducing your water use by a minimum of 20% at this critical time we may be able to avoid more serious shortages and lessen the impact of reduced water availability on our environment.

Level Three

The most severe low water level condition is declared when a the water supply no longer meets the demand and social, economic and environmental impacts to the watershed are occurring. When a level three warning is issued, restrictions from the Water Response Team approved by the Government of Ontario will be put into action.
