MASSENA– The New York Power Authority is warning residents of dangerous ice conditions on the St. Lawrence River downstream of the Long Sault Dam. 

Water released through the dam can rapidly impact the water currents and the condition of surface ice, creating unsafe conditions along the south channel of the river, downstream of the dam, NYPA said in a prepared statement.

The release of water at Long Sault Dam can occur with very little notice, so caution and awareness along the river are advised at all times. The power authority describes a safe distance as at least 800 feet from the dam, and advises residents to keep off the ice formed in the entirety of the south channel.

Temporary signage has been posted along the channel to inform the public when water is being released from the Long Sault Dam.
