Lake Ontario St. Lawrence River Plan 2014
Protecting against extreme water levels, restoring wetlands and preparing for climate change
The International Joint Commission, after 14 years of scientific study and public engagement, advances Plan 2014 as the preferred option for regulating Lake Ontario-St. Lawrence River water levels and flows.
Plan 2014 is designed to provide for more natural variations of water levels of Lake Ontario and the St. Lawrence River that are needed to restore ecosystem health. It will continue to moderate extreme high and low levels, better maintain system-wide levels for navigation, frequently extend the recreational boating season and slightly increase hydropower production. More year-to-year variation in water levels improves coastal health.
