Also included on the Lake Erie chart above is a provisional lake surge model forecast provided courtesy of the MNRF. This forecast is updated twice daily at 1:00 a.m. and 1:00 p.m. and provides a 48-hour forecast outlook of potential lake surge events.
Lake Erie levels are naturally impacted by many factors including wind, precipitation, and ice cover. Normal fluctuations in lake levels can happen both seasonally and longer-term. Unlike the lower St. Lawrence and Lake Ontario, Lake Erie is unregulated and human influences on water levels are negligible.
Lake Erie static levels typically peak in May/June each year due to spring runoff which causes the level of theGreat Lakes to rise.
Weather systems can cause water to surge on Lake Erie resulting in water levels increasing above the normal (static) level. There is a higher risk of seasonal lake surge events between November and April. Waves associated with these surge events can further increase water levels.
