Members of the Public Warned to Use Caution on the River

MASSENA–The New York Power Authority announced today that the gates at Long Sault Dam are scheduled to be open from 7 a.m. Thursday, April 4 until 3 p.m. Friday, April 5. The opening of the gates will result in rapidly changing river flows and potentially unsafe ice conditions downstream of the dam and along the South Channel of the river.

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 flier for a map detailing affected areas.

Members of the public should:

  • Use caution on the river.
  • 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.
  • Be aware of changing river conditions and strong currents.

The release of water Long Sault Dam will assist in maintaining the International Lake Ontario and St. Lawrence River Board’s (ILOSLRB) planned river flow while several turbine generators are out of service for maintenance at the Moses-Saunders Power Dam. The spilling will not increase the overall planned river flow.

Outflows from Lake Ontario are established on a weekly basis by the International Lake Ontario and St. Lawrence River Board (ILOSLRB). The Board, in conjunction with its staff, continues to monitor and reassess conditions on an ongoing basis. Information on hydrologic conditions, water levels and outflows are available on the Board’s website and posted to the Board’s Facebook page at https://www.facebook.com/InternationalLakeOntarioStLawrenceRiverBoard (English).

Actual outflows will depend on conditions in the St. Lawrence River. Spilling activities could take place through the spring.
