1,632-acre lake in Rainy River District, Ontario. The lake tops out around 115 ft. The depth data here comes from an MNRF lake survey by the Ontario MNRF. Species by species, here's what the data says the year looks like.
The outline encloses 1,640 acres, worked by 27.4 miles of shoreline, broken up by 22 islands. The 4.8 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 29% of this chart. Call it 4.3 mi long by 1.8 mi wide at the broadest reach. Rainy River District claims this one. If the bite dies, Ottertrack is 8 mi to the southeast.
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 35 to 115 ft game here, winter a 20 to 80 ft one. The chart's best answer is Deep basin — deep basin, 115 ft, prime for summer. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (22 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 35 to 115 ft | dawn | Deep basin (115 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (22 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (71 ft) | White tube jig, Airplane jig |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. Warm water sends them out to 40 to 90 ft; cold water stacks them in 25 to 70 ft. Break off the point is the standout, a drop-off at roughly 71 ft, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Shallow feeding flat (20 ft) | Small jig + waxworm, Blade bait (small) |

Spring puts cisco (lake herring) in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 40 to 80 ft; cold water stacks them in 20 to 60 ft. Break off the point is the standout, a drop-off at roughly 71 ft, rated good for summer cisco (lake herring). Plan around early morning in the warm months. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (115 ft) | Small silver spoon, Tiny swim jig (white) |

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. The spot to know is Main-lake point, a point in about 22 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | open water | 1/8 oz jig + minnow, Hair jig |

| Winter | 20 to 40 ft | dusk & dawn | Main-lake point (22 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Spring yellow perch concentrate at Back-bay flat, a prime-rated weed flat around 5 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
