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.

St.Lawrence River - Gananoque 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. Trish Richardson of Canadian Tire Gananoque boasts the river’s vast underwater structure and many islands and shoals. The St. Lawrence River holds a large amount of fish, and is a great place for both novice and expert anglers. Fishing around Wolfe Island can be very productive, having strong walleye and bass fisheries. Pike and muskie can also be found here, especially among the weed beds. Moving downstream, you will pass the town of Gananoque. Garry Fisher says that “the fishing is second to none” and the area known as the Thousand Islands is prime fishing habitat with countless shoals and ledges for the fish to call home. This area holds some of the best bass fishing the river has to offer. Smallmouth bass especially can be found along the rock piles and weed beds. They move into the shallow water to feed, so best to target them during dusk and dawn. They spawn in the shallows of the Thousand Islands and are most active just at the water is beginning to heat up in the spring. Fisher recommends using jerk or crankbaits. Anglers may also try drop-shotting to bounce along the bottom of the weedy areas. Largemouth bass are considerably more aggressive when compared to their smallmouth counterparts. They prefer thick weed coverage, coming out only to feed. Due to their aggression, Fisher suggests using topwater lures. Angler’s will be treated to a show as the bass ambush their bait. Try using frogs or poppers and head out at night or early morning as the fish are at their most aggressive during this time. St.Lawrence River - Brockville Further downstream, the river narrows and the current picks up speed approaching Brockville. Some of the largest muskies have been pulled out of the St. Lawrence River in this area, as well as has one of the most productive walleye fisheries. Pike, perch, and bass can also be found along the weed beds and islands, along with many other species. Typically, fishing is strongest between June and September. For those targeting muskie, you may want to extend that season into October and November, when the muskie come up to the shallower depths as the water cools. Look along the shoals and around the islands. Muskie prefer to be in 15 to 30 feet of water, and respond well to trolling lure such as Stalkers, Ernies, or Kriscos. It is not uncommon to catch northern pike over 10 pounds. They can usually be found in the shallows as they move into warmer water during the spring to feed. Pike are usually found with largemouth bass, so look for dense weeds that provide lots of cover. Spinners, Crankbaits and Jerkbaits have all been proven for pike, and using a flurocarbon fishing line is recommended.
