332-acre lake in Kenora District, Ontario. The lake tops out around 15 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 1985 (an MNRF lake survey). Species by species, here's what the data says the year looks like.
On the chart, Schroeml Lake draws 332 acres inside 3.8 miles of shoreline. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. Tip to tip the water measures near 1.6 mi with a 0.6-mi widest point. The water lies in Kenora District. The nearest mapped water is Overnight L., 3 mi to the north.
When the water first warms, walleye slide up into 4 to 15 ft. There's no big seasonal slide here — summer means 5 to 15 ft, winter 5 to 15 ft. Start at Deep basin. It's a deep basin holding about 13 ft of water and rates prime come winter. The feeding windows run the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
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 | 5 to 15 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Deep basin (13 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 15 ft chart-limited; documented 12 to 40 ft | dusk & night | Deep basin (13 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 15 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (13 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 5 to 15 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Deep basin: a deep basin around 13 ft that scores prime in fall. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
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 | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (13 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (13 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 5 to 15 ft, wintering in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
