367-acre lake in Kenora District, Ontario. The lake tops out around 49 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here's the year, species by species, as the scoring engine sees it.
On the chart, Rosen Lake draws 366 acres inside 7.3 miles of shoreline. An index of 2.7 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 63% of the surface on the model — that's where the groceries are. Call it 2.1 mi long by 0.9 mi wide at the broadest reach. The water lies in Kenora District. Closest neighbour on DepthScout: Little Bear Lake, 2 mi west of here.
Come spring, look for lake whitefish tight to the bank in 15 to 45 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 blade bait vertical or a small jigging spoon is the honest summer answer here.
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 | 15 to 45 ft | midday & dawn | Break off the point (22 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 15 to 49 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (42 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (22 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 15 to 49 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (42 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
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.
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 | 10 to 40 ft | dawn & dusk | Deep basin (42 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 15 to 49 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (42 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (22 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 15 to 49 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (42 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring walleye on Rosen 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 | Main-lake point (12 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) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: burbot in 15 to 49 ft. The depth story barely changes: 15 to 49 ft through summer, 12 to 49 ft in winter. Top water on the chart: Deep basin, a deep basin in the 42 ft range, prime in spring. Time it for after dark and midday. Summer baits: a heavy jig + cut bait 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 | 15 to 49 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (42 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 15 to 49 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (42 ft) | Heavy jig + cut bait |
| Fall | 15 to 49 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (42 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 12 to 49 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (42 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 42 ft.
