The volume level of water is one factor; I wouldn't say it's a major factor. Phosphorus is the controlling substance of all the things that affect algae growth. We think the way to influence the amount of algae in the lakes is to influence the amount of phosphorus entering the lakes. That's the current science.
Changes in water levels, in Georgian Bay in particular, might affect circulation patterns and could have an impact on algae growth, but we're still looking at that.
