MASSENA -- The New York Power Authority will release water through the Long Sault Dam on Friday, April 29, due to high St. Lawrence River flows and planned maintenance at the St. Lawrence-Franklin D. Roosevelt Power Project.
NYPA has also scheduled the replacement of three transformers at the power project. The replacement will result in a planned outage of four generating units for approximately three weeks.
The gates at Long Sault Dam are scheduled to be opened at 5 a.m. Friday. As a result, there could be rapidly changing water levels near the Long Sault Dam and the South Channel of the river. A siren near the Long Sault Dam will warn the public when water will be released from the gates.
Actual outflows will depend on conditions in the St. Lawrence River. SLRBC staff will monitor water levels to determine how long the gates of the control dam will remain open. Spilling activities could take place through May 21.
Outflows from Lake Ontario are established on a weekly basis by the international St. Lawrence River Board of Control (SLRBC). The action by NYPA will gradually reduce the water stored earlier this year on Lake Ontario.
