I don't think they are trying to or thinking about lowering the level of Superior. If anything they might be doing the opposite in order to help protect the lower lake levels. The real problems this year are in Erie and Ontario. While Superior is about 1 foot above average, Erie has been 2 feet high and Ontario almost 3 feet high. People think of Niagara Falls as the last big drop in lake levels between Erie and Ontario but Ontario is still about 240 feet above see level. There are 7 more sets of locks and dams on the St. Lawrence River. It is along these that water management has been focused. Accelerating the lowering of Lake Ontario does affect the Lake Superior area from the aspect that temporarily closing the shipping there does slow down the Saltys that need to get to Duluth.
