941-acre lake in Kenora District, Ontario. The lake tops out around 115 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 945 acres, worked by 19.1 miles of shoreline, with a single island in the mix. The 4.4 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 51% of the surface on the model — that's where the groceries are. Figure 4.6 mi of water from one end to the other, 1.2 mi at the beam. It sits in Kenora District. If the bite dies, Flossie Lake is 2 mi to the northeast.
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 35 to 115 ft, then a winter hold in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 98 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 (29 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 35 to 115 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (98 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (29 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (52 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. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 98 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 | Break off the point (52 ft) | Small jig + waxworm, Blade bait (small) |

| Fall | 8 to 30 ft | dusk | Main-lake point (29 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Break off the point (52 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring northern pike on Grant 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 weed 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 | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 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 Grant 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 Main-lake point first on the milk run — a point near 29 ft that grades prime for summer. 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 | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (29 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (29 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (52 ft) | Blade bait, Hair jig |
Spring puts rock bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 5 to 20 ft, wintering in 12 to 30 ft. Warm-month bites cluster around the evening. A ned rig (small) or a marabou jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | open water | Ned rig (small), Marabou jig |

| Winter | 12 to 30 ft | midday | open water | Tungsten jig + plastic, Small spoon + spike |
Early season burbot use the shallows, holding in 25 to 70 ft. Expect a summer slide to 35 to 115 ft, then a winter hold in 15 to 60 ft. Put Deep basin first on the milk run — a deep basin near 98 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.
