150-acre lake in Nipissing District, Ontario. The lake tops out around 22 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1974, a decades-old survey (an MNRF lake survey). Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 155 acres wrapped in 4 miles of bank. An index of 2.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. End to end it runs roughly 1.2 mi, about 0.6 mi across. It sits in Nipissing District. Its nearest charted neighbour, Olier Lake, is 1 mi to the northwest.
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 7 to 22 ft before dropping to 7 to 22 ft for winter. The spot to know is Deep basin, a deep basin in about 9 ft of water that rates prime for walleye in winter. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 7 to 22 ft | dusk & dawn | Deep basin (9 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 7 to 22 ft | dusk & night | Deep basin (9 ft) | Jigging rap, Jig + big minnow |
| Winter | 7 to 22 ft | dusk & dawn | Deep basin (9 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 7 to 22 ft before dropping to 7 to 22 ft for winter. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 9 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 7 to 22 ft | dawn | Deep basin (9 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 22 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 22 ft | midday & dawn | Deep basin (9 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| 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 bay flat (1 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Deep basin (9 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 |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Summer is a 7 to 22 ft game here, winter a 7 to 22 ft one. The chart's best answer is Deep basin — deep basin, 9 ft, good for winter. Best bite is early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 7 to 22 ft | dawn & dusk | Break off the point (1 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 7 to 22 ft | midday & dawn | Main-lake point (1 ft) | Jerkbait, Blade bait |
| Winter | 7 to 22 ft | midday | Deep basin (9 ft) | Blade bait, Hair jig |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 9 ft.
