Low Water Conditions

The MNR Surface Water Monitoring Centre staff notify and confer with conservation authorities, the Ministry of Environment, Ministry of Agriculture, Foods and Rural Affairs, Municipal Affairs and housing and local MNR staff when streamflow and weather data indicate that an area may be in a Level I, II or III low water condition. Levels I, II, III are described in the Ontario Low Water Response Plan. 

A summary and brochure of the Ontario Low Water Response program has been created to assist Water Response Teams to apply the program to their watershed.
