“The International Lake Superior Board of Control, under authority granted to it by the International Joint Commission, expects to increase the Lake Superior outflow for the month of May.
The increased outflow is expected to exceed the capacities of the hydropower plants on the St. Marys River in May, and therefore the excess will be released through the control structure at the head of the St. Marys Rapids.
“The outflow of Lake Superior will be adjusted over the next several months to accommodate expected maintenance at the hydropower plants, and to reduce the potential for adverse consequences of high and fluctuating flows in the St. Marys Rapids.”
