I've been fishing in a canoe on the St. Lawrence, which, BTW, is known as "The River" by locals. There are plenty of places, little tributaries, off the river which are ideal for flat-bottom vessels. I was always catching bass the weekend before the season started...ugh. Hated to have to throw them back...actually, I resuscitated them first. Plenty of perch...no limit...in the Cape Vincent area. Trout in some of the inland streams. Bullheads, which are cousins to catfish, which are available also, are red-fleshed...not so easily caught, best to go either at 6AM or 6PM, and hunker down. Lots of trophy fish, if you can afford a guide. Muskies and such.
The Lake's great, too, even in small boats as long as you stay near the shore. I remembered you'll need a passport now if you plan on heading over to Canada. Wellesley Island, last US stop, is a great area to fish in. Also has 3 golf courses that aren't hard on the pocket book. Actually, there are quite a few golf courses on the mainland, too. Some picturesque...some plain and simple. Something for everyone! I'm a birder, too, ranger1. I miss the Blue Herons...there's a huge population up there. Lots of hawks, too.
