Angelo with his enormous Lake St. Francis muskie.

Lake St Francis, Ontario

Location: Lake St. Francis, Ontario
GPS: N45º 04.083′ W074º 31.591′
Species: Muskie

This Muskellunge Hotspot is a drop-off in Lake St FrancisTrophy muskie live throughout this body of water, giving anglers a good chance at catching a true giant. Fish’n Canada hosts Angelo Viola and Pete Bowman both caught their personal best muskies on Lake St Francis within mere moments of each other—this thrilling once-in-a-lifetime experience was captured for the episode “Saint Francis Titans.”

Ang and Pete drifted a custom rig with a one-ounce weight designed by their guide and good buddy Ryan Flaro right through the spots he put them on. 

Ang and Pete highly recommend that you hire a Muskie Guide for this water because of its expansive size, and because of the very specific areas that these underwater leviathans use to feed.

  1. The “Venturi Effect” we see here in Lake St. Francis on the St. Lawrence River as it races between these islands is quite a doozie.

    First, I’ll outline again what I mean by the “Venturi Effect”….

    The Venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section (or choke) of a river.
    In fluid dynamics, an incompressible fluid’s velocity must increase as it passes through a constriction in accord with the principle of mass continuity, while its static pressure must decrease in accord with the principle of conservation of mechanical energy. Thus any gain in kinetic energy a fluid may occur due to its increased velocity through a constriction is balanced by a drop in pressure.

    The Muskellunge, also known as muskelunge, muscallonge, milliganong, or maskinonge, has a little pea brain that seems to be a lot more intelligent than we assume. As the water flows through the “Venturi” of these islands, it exits at a lower pressure on the upstream side, funneling and concentrating the forage fish to the awaiting predators. The Muskies, like all ambush creatures, spend less time and energy chasing down a meal in these areas.

    There is a vitally important fact in the above article that every angler should understand. As recommended, you should hire a Muskie Guide for this water because of its expansive size, and because of the very specific areas that these underwater leviathans use to feed.

    Muskies by nature, live somewhat of a sedentary lifestyle by defending their watery “turf” from other invading fish, although they do form small schools on occasion likely for feeding purposes. Hence the guides importance to knowing where these feeding areas are located in the “Venturi”.

    Here are a few fun facts….
    1) Muskies move most during spring. Fall is the next most-active season. They are least active during summer. Muskie movements do not vary much by time of day during spring and fall. Fish were more active at night than at dusk or dawn or during the day during the summer.

    2) As might be expected, movement decreases as water temperature rises. Movement increases as water temperature decreases.

    3) Muskies were more likely to be found in open water in spring. Next popular place is wood cover such as fallen timber and brush; then cames plants; and finally bare shoreline. In summer, they used open water, wood and plants equally.

    4) During the summer, muskies moved to the warmest, shallowest water of the lake. The fish are typically forced higher in hot weather as oxygen levels in deeper water become too low to support life. Yet, even though cooler water with enough oxygen for them was available slightly deeper, the muskies chose to stay higher in the water column. Muskies were likely there to chase food or to use cover, such as weeds and rocks.


    Tiger Muskies, in fact all Muskellunge, have been known to occasionally (but very rarely) attack people. Muskie don’t have cutting teeth like a shark does. They puncture and grab. So a Tiger Muskie isn’t trying to eat you. They are only hunting and hunting prey that they can swallow. If you get bitten, it is because you were complacent when landing the fish dangling your hand over a dock or boat. The Muskie likely mistook your appendage as something it could eat. More often in very murky water?

    They are indeed a vicious predatory fish! And a terror to its prey. But humans aren’t on the menu. If you get bit, it was just a very unlucky day for you and the muskie made a mistake.

    Those hungry Muskellunge are one heck of an ambush predator!! That theme from “Jaws” has acquired a whole new meaning!
