3,274-acre lake in Rainy River District, Ontario. The lake tops out around 256 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 3,289 acres, worked by 44.5 miles of shoreline — 41 islands included. That shoreline is heavily fingered (development index 5.5) — bays, points and pockets everywhere, which multiplies the fishable edge. Littoral water — the productive band under ~15 ft — makes up 27% of this chart. Tip to tip the water measures near 7.2 mi with a 2.2-mi widest point. Rainy River District claims this one. Its nearest charted neighbour, Conk Lake, is 1 mi to the northwest.
Spring lake trout on Jean Lake hold shallow, usually 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. Put Shoreline point first on the milk run — a point near 10 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Shoreline point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Sharp break (85 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Shoreline point (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Sharp break (85 ft) | White tube jig, Airplane jig |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Midsummer fish sit out in 40 to 90 ft before dropping to 25 to 70 ft for winter. Summer lake whitefish concentrate at Sharp break, a prime-rated drop-off around 85 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.

|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Rock reef (4 ft) | Small jig + waxworm, Blade bait (small) |

Fall cisco (lake herring) concentrate at Rock reef, a prime-rated rock pile around 4 ft. Fish it in early morning and you'll meet the bite. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.

The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Top water on the chart: Rock reef, a rock pile in the 4 ft range, prime in spring. Time it for the evening and early morning. 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 | Rock reef (4 ft) | 1/8 oz jig + minnow, Hair jig |

In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
