Low Water Status

Historically, periods of dry weather and low water levels or drought have been relatively uncommon in Ontario (about every 10-15 years). However, recent studies on changing weather patterns indicate low water levels may become more common, potentially compounded by the province’s steadily increasing demands for water.

Conservation Sudbury, in partnership with the Ministry of Natural Resources and Forestry, helps coordinate and support local response in the event of a drought as part of the Ontario Low Water Response Program. There are three levels of low water advisories.

Types of Messages

Normal
Generally indicates low flow to base flow conditions. It should be noted that during Normal flow conditions, the inherent risk to personal safety associated with flowing water still exists.
LEVEL 1 - Low Water Condition
Low water condition is the first of three levels and is the first indication of a potential water supply problem. Condition – Flows are less than 70 percent of their normal summer low flow and/or precipitation has been less than 80 percent of average. Action – Water users will be asked to voluntarily reduce their water consumption by 10%
LEVEL 2 - Low Water Condition
Suggests a potentially serious problem. Condition – Flows are less than 50 percent of their normal summer low flow and/or precipitation has been less than 60 percent of average. Action – Water users will be asked to voluntarily reduce their water use by 20% or greater.
LEVEL 3 - Low Water Condition
Represents the most severe drought condition and indicates that the water supply can no longer meet the demand. Condition – Flows are less than 30 percent of their normal summer low flow and/or precipitation has been less than 40 percent of average. Action – Voluntary measures have not produced the necessary response. Restrictions proposed by the Water Response Team and approved by the Government of Ontario will be put into action.
