369-acre lake in Rainy River District, Ontario. The lake tops out around 59 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 1979, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 371 acres, worked by 8.4 miles of shoreline, with 3 islands in the mix. The 3.1 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 28% of the surface — that's where the groceries are. Figure 1.6 mi of water from one end to the other, 1.1 mi at the beam. Rainy River District claims this one. If the bite dies, Dragon Lake is 1 mi to the north.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

When the water first warms, lake trout slide up into 10 to 40 ft. Summer is an 18 to 59 ft game here, winter a 15 to 59 ft one. Start at Deep basin. It's a deep basin holding about 59 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (20 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 18 to 59 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (59 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (20 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 15 to 59 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (59 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 18 to 59 ft; cold water stacks them in 18 to 59 ft. Top water on the chart: Deep basin, a deep basin in the 59 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (28 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 18 to 59 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (59 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (28 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 18 to 59 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (59 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 18 to 59 ft; cold water stacks them in 18 to 59 ft. Top water on the chart: Deep basin, a deep basin in the 59 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 | Break off the point (28 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 18 to 59 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (59 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (28 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 18 to 59 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (59 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 4 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 (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (28 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (28 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (28 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (19 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Secondary point (10 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
Spring green sunfish on Nevison Lake hold shallow, usually 1 to 8 ft. They move out to 2 to 12 ft in summer and finish the year down in 8 to 22 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a micro jig or a small grub.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday | Shallow bay flat (4 ft) | Micro jig, Tiny beetle-spin |
| Summer | 2 to 12 ft | dawn & dusk | Shallow bay flat (4 ft) | Micro jig, Small grub |
| Fall | 4 to 16 ft | midday | open water | Small jig, Micro crankbait |
| Winter | 8 to 22 ft | midday | Break off the point (28 ft) | Tiny hair jig, Micro spoon |
