Dear Juro & Dmas,
Today there is a small but increasing number of Atlantics ascending the tribs of Lake Ontario. Fish and Game has worked very hard toward this goal. The Salmon River is one of them. During July the dam released water is increased to give good flow for recreational kayaks and the Salmon move up the river.
In addition I have heard that fish from the original eggs that were transported to South America for seeding are alive and well and are of Lake Ontario origin. I am hoping that what was taken will return.
