WRVO's Payne Horning reports When water levels reach a certain height, the International Lake Ontario-St. Lawrence River Board is given the power to deviate from Plan 2014, meaning they can increase outflows to whatever level necessary to avoid flooding. Accordingly, Plan 2014 does not dictate or offer much guidance on what the Board should do after deviating. However, the members don't have free rein to do whatever they want as there are various populations, everyone from shoreline residents to the shipping industry to environmentalists and more, to keep in mind. That's where the so-called Decision Support Tool comes in. Bernie Gigas, an engineer and member of the group reviewing Plan 2014, said it's like a program or code based on historical water supply records that can simulate what could happen from different decisions.
