From Niagara Frontier Publications (from last Friday):
Placement of the 22 spans of the Lake Erie-Niagara River ice boom is about to start.
Each winter since 1964, the Lake Erie-Niagara River ice boom has been installed near the outlet of Lake Erie to reduce the amount of ice entering the Niagara River. Reduction in ice entering the river reduces the potential for ice jams, which can result in damage to shoreline property and significantly reduce water flow for hydroelectric power production.
Under the International Joint Commission’s 1999 Supplementary Order of Approval, placement of the spans may begin when the Lake Erie water temperature at Buffalo reaches 4ºC (39ºF) or on Dec. 16, whichever comes first. Installation of the ice boom is planned to begin today, weather permitting.
