2,848-acre lake in Thunder Bay District, Ontario. The lake tops out around 110 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What the data behind the map says about each species, season by season:
The drawn water covers 2,856 acres wrapped in 38.8 miles of bank, with 10 islands in the mix. With a shoreline index of 5.2, this water is all arms and coves — edge habitat well beyond its acreage. 18% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 7.8 mi with a 1.8-mi widest point. It sits in Thunder Bay District. If the bite dies, Rudge Lake is 4 mi to the south.
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 33 to 110 ft, then a winter hold in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 94 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (28 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 33 to 110 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (94 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Rock reef (11 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (50 ft) | White tube jig, Airplane jig |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 40 to 90 ft, wintering in 25 to 70 ft. Fall lake whitefish concentrate at Rock reef, a prime-rated rock pile around 11 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Rock reef (11 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Deep basin (94 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (11 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Break off the point (50 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Shallow bay flat is the standout, a feeding flat at roughly 6 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Offshore hump (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Offshore hump (13 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Offshore hump (13 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on Baril Lake hold shallow, usually 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Put Shallow bay flat first on the milk run — a feeding flat near 6 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline point (12 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shoreline point (12 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
Spring smallmouth bass on Baril Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 20 to 45 ft. Put Rock reef first on the milk run — a rock pile near 11 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Rock reef (11 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Offshore hump (13 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Shoreline point (12 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (50 ft) | Blade bait, Hair jig |
Early season burbot use the shallows, holding in 25 to 70 ft. Expect a summer slide to 33 to 110 ft, then a winter hold in 15 to 60 ft. Put Deep basin first on the milk run — a deep basin near 94 ft that grades prime for summer. In summer the feeding windows fall in after dark and midday. Tie on a heavy jig + cut bait and you're in the game.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
