MASSENA— The New York Power Authority would like to remind recreational users of the St. Lawrence River to be aware of potential changes in river conditions during the winter season and to heed the warnings.

 

The release of water through the Long Sault Dam will result in rapidly changing river flows and potentially unsafe ice conditions along the South Channel of the river, downstream of the dam. When warnings are issued, members of the public, including those ice fishing on the river or channel, should be alert to rapidly changing ice conditions and should stay off the ice. See safety flier for a map detailing affected areas.

 

  • Temporary signage has been posted along various locations near the South Channel to inform the public when water is being released from the Long Sault Dam. 

Members of the public should:

  • Keep back a minimum of 800 ft. from the Long Sault Dam spillway and Robert Moses Power Dam, both on the upstream and downstream side
  • Use caution on and near the river
  • Be aware of changing river conditions and strong currents

The release of water at Long Sault Dam can occur with very little notice, so caution and awareness along the river, especially in the South Channel, and near the Long Sault Dam spillway and the Robert Moses Power Dam, is advised at all times.

Water flows from Lake Ontario into the St. Lawrence River are governed by the International Joint Commission (IJC). Outflows from Lake Ontario are established on a weekly basis by the International Lake Ontario and St. Lawrence River Board (ILOSLRB). The ILOSLRB monitors water levels and oversees water releases with the U.S. Army Corps of Engineers on the U.S. side and the Environment Canada on the Canadian side monitoring day-to-day activities. Information on water levels can be obtained at: http://ijc.org/en_/islrbc.

Actual outflows will depend on conditions in the St. Lawrence River. Spilling activities are expected to take place through the remainder of winter and through the spring.
