939-acre lake in Thunder Bay District, Ontario. The lake tops out around 7 ft. The depth data here comes from the Ontario MNRF survey of 1989 (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Upper Kaogomok Lake runs 943 acres with 10.3 miles of edge — 4 islands included. An index of 2.4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 2.3 mi long by 1.3 mi wide at the broadest reach. The water lies in Thunder Bay District. For a second option, Buck Lake lies 11 mi northeast.
Early season lake whitefish use the shallows, holding in 2 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 2 to 7 ft. Put Deep basin first on the milk run — a deep basin near 7 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | midday & dawn | Break off the point (7 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 2 to 7 ft | dawn | Deep basin (7 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 2 to 7 ft | dusk | Break off the point (7 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 2 to 7 ft | midday & dawn | Deep basin (7 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season cisco (lake herring) use the shallows, holding in 2 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 2 to 7 ft. Put Deep basin first on the milk run — a deep basin near 7 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a vertical flutter spoon (small) or a drop-shot micro plastic and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | dawn & dusk | Deep basin (7 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 2 to 7 ft | dawn | Deep basin (7 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 1 to 7 ft | dusk & dawn | Break off the point (7 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 2 to 7 ft | dawn | Deep basin (7 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Come spring, look for yellow perch tight to the bank in 2 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 2 to 7 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 7 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 7 ft | midday | Deep basin (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 7 ft | midday & dawn | Deep basin (7 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 7 ft that time of year. They don't go far with the seasons — 2 to 7 ft covers summer, 2 to 7 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for northern pike in spring. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 7 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 7 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
