163-acre lake in Timiskaming District, Ontario. The lake tops out around 14 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Here's the year, species by species, as the scoring engine sees it.
On the chart, Otto L. draws 163 acres inside 3.2 miles of shoreline — one island included. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 0.9 mi, about 0.6 mi across. You'll find it in Timiskaming District. Closest neighbour on DepthScout: Vigrass Lake, 1 mi west of here.
Come spring, look for walleye tight to the bank in 4 to 14 ft. Through summer count on 4 to 14 ft; the winter hold is 4 to 14 ft. Start at Break off the point. It's a drop-off holding about 6 ft of water and rates prime come fall. Prime time lands in the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 14 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 4 to 14 ft | dusk & dawn | Break off the point (6 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 4 to 14 ft | dusk & night | Break off the point (6 ft) | Jigging rap, Jig + big minnow |
| Winter | 4 to 14 ft | dusk & dawn | Deep basin (12 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 4 to 14 ft in summer and finish the year down in 4 to 14 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is 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 | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 14 ft | dawn | Deep basin (12 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 14 ft | midday | Deep basin (12 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 14 ft | midday & dawn | Deep basin (12 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 4 to 14 ft; cold water stacks them in 4 to 14 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. 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 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 4 to 14 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 14 ft | midday & dawn | Break off the point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 14 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
When the water first warms, lake sturgeon slide up into 3 to 14 ft. There's no big seasonal slide here — summer means 4 to 14 ft, winter 4 to 14 ft. If you only fish one area, make it Deep basin: a deep basin around 12 ft that scores prime in fall. In summer the feeding windows fall in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 14 ft | dusk & night | open water | |
| Summer | 4 to 14 ft | night & dusk | Deep basin (12 ft) | |
| Fall | 4 to 14 ft | dusk | Deep basin (12 ft) | |
| Winter | 4 to 14 ft | midday | Deep basin (12 ft) |
6 pieces of structure are mapped here — Deep basin, around 12 ft, is the deepest of them.
