Proposal for Lake Ontario and St. Lawrence River Regulation

Water Levels: Plan 2014 vs. Actual

Plan 2014 Water Levels and Actual Water Levels: 2001-2015

These graphs compare the actual recorded water levels from 2001-2015 and simulated water levels for Plan 2014 using the same water supplies. The simulated Plan 2014 levels were reviewed on a week-by-week basis to include flow adjustments and deviations from the plan flow that the IJC Board would likely have made in response to actual circumstances during this time period. Differences in peak elevations and beginning of October elevations are noted for each year.
