The regulatory plan was released this week by the International Joint Commission, which represents both the U.S. and Canada. It is intended to restore diversity in shoreline plant and animal communities by permitting greater fluctuations in water levels.

Jennifer Caddick is executive director of Save the River. She says organization has endorsed it:

"I think this plan is a strong balanced approach that helps us balance the many sometimes-competing needs on the system. So I think this is a great step forward." 

The new plan allows water levels to stay high or low for longer periods than the current plan does. She says the more natural fluctuations will benefit wetland habitats, and the fish that depend on them. 

But some businesses and citizens are concerned that the plan will cost them money, and will negatively affect the tourist economy.

The Save the River conference is tomorrow at the Clayton Opera House.
