The International Joint Commission is taking another stab at a plan to regulate Lake Ontario and St. Lawrence Seaway water levels. | The IJC today released an overview of its approach and is accepting public comments on it. Comments received before June 15 will be considered while IJC develops its draft plan, says a press release from the commission. | The plan will allow for natural variations in the lake and seaway levels. The existing plan, which is from 1963, doesn't take environmental factors into consideration and coastal wetlands have suffered as a result. Allowing water levels to fluctuate naturally will help restore the plant diversity of the wetlands, which will provide better habitat along the lakeshore.| The plan is intended to prevent flooding along the lakeshore while maintaining levels necessary for boating, port operations, and hydropower production at the Moses-Saunders dam. | The IJC last proposed a lake level management plan in 2007. New York officials, Ontario provincial officials, and environmentalists favored an option that allowed for natural fluctuations, while recreational and commercial boaters favored a plan that kept levels steadier. The IJC offered a compromise plan, but eventually withdrew it.
