1,743-acre lake in Kenora District, Ontario. The lake tops out around 30 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 1987 (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 1,747 acres wrapped in 18.5 miles of bank, broken up by 6 islands. A development index of 3.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 3.8 mi long by 1.8 mi wide at the broadest reach. Kenora District claims this one. Roderick Lake sits 8 mi northeast — the closest neighbouring chart.
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 9 to 30 ft, wintering in 9 to 30 ft. Top water on the chart: Deep basin, a deep basin in the 23 ft range, prime in winter. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
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 | 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 9 to 30 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Deep basin (23 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 9 to 30 ft chart-limited; documented 12 to 40 ft | dusk & night | Deep basin (23 ft) | Jigging rap, Jig + big minnow |
| Winter | 9 to 30 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (23 ft) | Jigging spoon + minnow head, Rattle bait |
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 9 to 30 ft. Deep basin is the standout, a deep basin at roughly 23 ft, rated prime for fall 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.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (23 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (23 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (23 ft) | Tungsten jig + spikes, Rattle spoon (small) |
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 1 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.
| 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 | open water | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (1 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
Spring burbot on Mimi Lake hold shallow, usually 9 to 30 ft. Depth-wise the year is flat: 9 to 30 ft in summer, 8 to 30 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 23 ft that grades prime for spring. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.
