Ice Thickness Flight
The U.S. Army Corps of Engineers, Buffalo District and Environment Canada took a helicopter out onto Lake Erie to measure actual ice thickness at six preselected locations. The International Joint Commission's International Niagara Board of Control, established in 1953 to monitor activities concerning the levels and flows of the Niagara River, intensively monitors the ice situation each spring to determine when conditions are acceptable for boom removal. Boom opening is dependent on weather, ice conditions in Lake Erie and the Niagara River, among other factors.
