The U.S. Army Corps of Engineers releases the third ‘On the Level,’ Great Lakes water level and forecast video.
From the head of the St. Marys River in Sault Ste. Marie, Michigan, Hydraulic Engineer Missy Kropfreiter discusses the International Joint Commission and Lake Superior regulation.
“The goal of regulation is to maintain a balance of Lake Superior and Lake Michigan-Huron with respect to long-term average water levels based on average conditions,” according to Kropfreiter. “Although Lake Superior’s outflow is regulated, lake level control cannot be achieved through regulation. Lake levels are driven by the net basin supply such as precipitation, runoff and evaporation.”
