Recreational Boaters and Members of the Public Advised to Take Caution Along River


MASSENA — The New York Power Authority (NYPA) announced today that the gates at Long Sault Dam are scheduled to be open from 5 a.m. until 8 p.m. on Saturday, May 25, resulting in the release of excess water in the St. Lawrence River. This spill will result in changing river flows.
Members of the public, including those boating on the river or channel, should be alert to rapidly changing conditions. 

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 at Long Sault Dam will assist in maintaining the International Lake Ontario and St. Lawrence River Board's (ILOSLRB) planned river flow. Actual outflows will depend on conditions in the St. Lawrence River. Spilling activities could take place throughout the summer months, and members of the public are encourage to look for signage and public notifications when accessing the river.

Outflows from Lake Ontario are established on a weekly basis by the 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).
