The flow of water out of Lake Ontario will continue to be set at nearly 2.7 million gallons per second for at least one more week, the International Joint Commission said Thursday.
That's the fastest outflow ever allowed from the lake since the creation of the St. Lawrence Seaway in the late 1950s. It matches records set in 1993 and 1998.
The binational Great Lakes regulatory agency said it will maintain the outflow rate, first set on May 23, in an effort to provide flood and erosion relief for property owners along the lakeshore without making the situation more dangerous in the Montreal area, where high water produced flooding this spring.
The average water level in the lake decreased 1 inch in the past week despite some rain in the region, the commission said. The level remains 31.5 inches higher than the seasonal average, but in Montreal, the water is 53.9 inches above normal.
