Advances in understanding form the basis for the new approach, which seeks to restore greater balance to the region's regulation of water levels and flows. Studies show that modest changes in water level variability on Lake Ontario and the upper St. Lawrence River would help restore the region's wetlands and contribute significantly to a healthier lake and river. At the same time, other basin interests would retain most of the benefits they now receive in the form of reduced extreme high and low water levels. Expected results and any unforeseen consequences would be systematically monitored and evaluated under the adaptive management strategy.
