How can high or low Lake Ontario water levels affect domestic and sanitary uses?
• Lake Ontario water levels above the upper limit of the regulation range have resulted in threats to domestic supplies and sanitary uses. These consist of flooding and back-up of sanitary sewer lines, flooding and contamination of freshwater storage wells and, under very high levels or during storm events, possible flooding of freshwater intake pumping facilities. Low levels can impair the functioning of intakes, reducing their capacity.
