About St. Lawrence River
All water flowing from the Great Lakes passes through the St. Lawrence River, making it one of the largest river systems in the country. Throughout this river, there are more than 20 species of sport fish to target.
The river begins at Kingston, where Lake Ontario begins to narrow around Wolfe Island and starts its journey to the Atlantic Ocean. Fishing around Wolfe Island can be very productive, having strong walleye and bass fisheries. Pike and muskellunge can also be found here, especially among the weed beds.
Moving downstream, you will pass the town of Gananoque, an area referred to as the Thousand Islands. As the name implies, this is prime fishing habitat with countless shoals and ledges for the fish to call home. Just past Gananoque you reach Ivy Lea Campground --the first park of the St. Lawrence Parks Commission-- and a great place to camp when fishing the 1000 Islands.
Further downstream, the river narrows and the current picks up speed approaching Brockville. Between Brockville and Cornwall there are four more campgrounds operated by the St. Lawrence Parks Commission, along with Crysler Park Marina. Of particular note is Hoople Creek Basin, located beside Long Sault Parkway. This is considered to be one of the most productive walleye fisheries in eastern Canada. Past Cornwall, the river flows towards Montreal, where there is one more campground called Glengarry. This campground boasts some of the best carp and bass fishing around.
Typically, fishing is strongest between June and September. For those targeting Muskellunge, you may want to extend that season into October and November, when the muskie come up to the shallower depths as the water cools. It is not uncommon to catch northern pike over 10 pounds, and bass over five pounds in the St. Lawrence.
There are several charter operations that operate on the St. Lawrence. Several are based in Gananoque and Brockville, and will teach you their trade secrets on how to fish these waters.
Remember that the St. Lawrence River shares a border with the United States. Use navigation charts if you are planning to get close to it.
