Water levels on Lake Ontario and the St. Lawrence River have remained stable for almost two weeks now, remaining at historic highs. When the waters begin to lower and by how much will depend on the weather.Keith Koralewski with the U.S. Army Corps of Engineers said, "If we have a drier scenario, we will certainly start to see it peak in the next couple weeks and then begin to go down. If it’s more the average scenario, it may take more like a three or four week time before the levels start to go down. And certainly if it’s a very wet scenario, like we experienced in April and that first week of May, there is still a possibility that water levels still could go up before they go down."Koralewski says regulators are releasing record volumes of water through the hydropower dam in Massena to help bring down the water level. The problem is, the Great Lakes, like Lake Erie, which empty into Ontario, are higher than normal, too. "And so there’s above average flows coming in to Lake Ontario. So it’s a matter of trying to have the outflows exceed the inflows," he said.Towns along the Thousand Islands and eastern Lake Ontario in Jefferson County have been scrambling to get their waterfronts in shape for tourist season.In the Rochester area, along the lake’s southern shore, flooding has damaged some businesses. Owners say it will take a long time to recover even after the floodwaters recede.
