5,689-acre lake in Rainy River District, Ontario. The lake tops out around 20 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 5,714 acres, worked by 64.1 miles of shoreline, broken up by 39 islands. The 6.1 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. 87% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 7.6 mi of water from one end to the other, 5.2 mi at the beam. It sits in Rainy River District. Its nearest charted neighbour, Mong Lake, is 5 mi to the northwest.
The spring pattern is a shallow one: lake whitefish in 6 to 20 ft. The depth story barely changes: 6 to 20 ft through summer, 6 to 20 ft in winter. Top water on the chart: Deep basin, a deep basin in the 20 ft range, prime in summer. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 20 ft | midday & dawn | Sharp break (13 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 5 to 20 ft | dusk | Gravel shoal (2 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: cisco (lake herring) in 5 to 20 ft. The depth story barely changes: 6 to 20 ft through summer, 6 to 20 ft in winter. Top water on the chart: Deep basin, a deep basin in the 20 ft range, prime in spring. Time it for early morning. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Deep basin (20 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 4 to 20 ft | dusk & dawn | Gravel shoal (2 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 6 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 6 to 20 ft; cold water stacks them in 6 to 20 ft. Sharp break is the standout, a drop-off at roughly 13 ft, rated prime for fall walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Gravel shoal (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 20 ft | dusk & dawn | Sharp break (13 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 20 ft | dusk & night | Sharp break (13 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 20 ft | dusk & dawn | Deep basin (20 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, sauger run shallow here, mostly 4 to 18 ft. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. Deep basin is the standout, a deep basin at roughly 20 ft, rated prime for winter sauger. Time it for early morning and the evening. You won't need more than a bottom bouncer + crawler or a 3-way rig with stickbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 18 ft | dawn & dusk | Gravel shoal (2 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |
| Summer | 6 to 20 ft | dawn & dusk | Sharp break (13 ft) | Bottom bouncer + crawler, 3-way rig with stickbait |
| Fall | 6 to 20 ft | dusk & dawn | Sharp break (13 ft) | Jig + big minnow, Blade bait |
| Winter | 6 to 20 ft | dusk | Deep basin (20 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 6 to 20 ft; cold water stacks them in 6 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 20 ft range, prime in fall. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Feeding flat (10 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Sharp break: a drop-off around 13 ft that scores prime in fall. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| 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 | Sharp break (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Sharp break (13 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
