776-acre lake in Algoma District, Ontario. The lake tops out around 25 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What the data behind the map says about each species, season by season:
Come spring, look for lake whitefish tight to the bank in 8 to 25 ft. Through summer count on 8 to 25 ft; the winter hold is 8 to 25 ft. If you only fish one area, make it Deep basin: a deep basin around 25 ft that scores prime in summer. Best bite is early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 25 ft | midday & dawn | Shallow feeding flat (20 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 8 to 25 ft | dawn | Deep basin (25 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 7 to 25 ft | dusk | Break off the point (4 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 8 to 25 ft | midday & dawn | Deep basin (25 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring walleye on Obatanga Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 8 to 25 ft, and by winter most fish are in 8 to 25 ft. The chart's best answer is Deep basin — deep basin, 25 ft, prime for winter. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Break off the point (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 25 ft | dusk & dawn | Deep basin (25 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 25 ft | dusk & night | Deep basin (25 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 25 ft | dusk & dawn | Deep basin (25 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 1 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (20 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (4 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
