The Lake Erie-Niagara River ice boom is in place for the winter.
Crews began installing the 1.7-mile long ice boom on schedule Saturday and finished Sunday, according to Lou Paonessa, a spokesman for the New York Power Authority.
The boom is installed when the temperature of Lake Erie reaches 39 degrees, which happened last Thursday.
The International Joint Commission authorizes the New York Power Authority and Ontario Power Generation to use the boom to reduce ice floes into the Niagara River, which can damage power generation equipment and result in erosion along the shorelines of the Niagara River and along its in-river islands.
Paonessa said the ice boom installation won't have any affect on this week's planned departure of the newly commissioned USS Little Rock.
