5,070-acre lake in Sudbury District, Ontario. The lake tops out around 49 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 5,066 acres of water rimmed by 98 miles of bank, broken up by 8 islands. That shoreline is heavily fingered (development index 9.8) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 89% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 9.6 mi with a 6.3-mi widest point. The water lies in Sudbury District. The nearest mapped water is Clifton Lake, 4 mi to the east.
Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. Expect a summer slide to 15 to 49 ft, then a winter hold in 15 to 49 ft. Start at Deep basin. It's a deep basin holding about 42 ft of water and rates prime come summer. Prime time lands in early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (42 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 15 to 49 ft | dawn | Deep basin (42 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Rock reef (4 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 15 to 49 ft | dawn | Deep basin (42 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring walleye on Little Missinaibi Lake hold shallow, usually 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 20 to 40 ft. Put Break off the point first on the milk run — a drop-off near 22 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| 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 |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (22 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (22 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (42 ft) | Jigging spoon + minnow head, Rattle bait |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (22 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (22 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (42 ft) | Tungsten jig + spikes, Rattle spoon (small) |
