370-acre lake in Nipissing District, Ontario. The lake tops out around 46 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:
The outline encloses 371 acres, worked by 7.5 miles of shoreline, with 4 islands in the mix. An index of 2.8 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 49% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 2.2 mi long by 0.7 mi wide at the broadest reach. Nipissing District claims this one. Its nearest charted neighbour, Coot Lake, is 1 mi to the south.
When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 14 to 46 ft game here, winter a 12 to 46 ft one. Start at Deep basin. It's a deep basin holding about 46 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (31 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 14 to 46 ft | dawn | Deep basin (46 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 9 to 46 ft | dusk & dawn | Main-lake point (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 12 to 46 ft | dawn | Deep basin (46 ft) | White tube jig, Airplane jig |
Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Warm water sends them out to 14 to 46 ft; cold water stacks them in 14 to 46 ft. Top water on the chart: Deep basin, a deep basin in the 46 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (31 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 14 to 46 ft | dawn | Deep basin (46 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (31 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 14 to 46 ft | midday & dawn | Deep basin (46 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. Warm water sends them out to 14 to 46 ft; cold water stacks them in 14 to 46 ft. Top water on the chart: Deep basin, a deep basin in the 46 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (46 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 14 to 46 ft | dawn | Deep basin (46 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 14 to 46 ft | dawn | Deep basin (46 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| 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 | 10 to 30 ft | dawn | Break off the point (31 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (31 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (31 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 20 to 45 ft. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (31 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (31 ft) | Blade bait, Hair jig |
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Warm water sends them out to 2 to 10 ft; cold water stacks them in 6 to 18 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in the evening and early morning and you'll meet the bite. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |

| Winter | 6 to 18 ft | dawn | Back-bay flat (4 ft) | Tungsten ice jig + plastic, Tiny spoon |
