97-acre lake in Rainy River District, Ontario. The lake tops out around 20 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 1980 (an MNRF lake survey). Species by species, here's what the data says the year looks like.
Drawn out, this is 99 acres of water rimmed by 3.4 miles of bank. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 98% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 0.9 mi end to end and 0.5 mi across at its widest. The water lies in Rainy River District. Closest neighbour on DepthScout: Muskeg Lake, 1 mi south of here.
When the water first warms, rock bass slide up into 2 to 10 ft. By summer they slide out to 5 to 20 ft, and by winter most fish are in 6 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 7 ft that scores prime in fall. In summer the feeding windows fall in the evening. Keep a ned rig (small) or a marabou jig 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 | 2 to 10 ft | midday & dawn | Main-lake point (1 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Break off the point (7 ft) | Ned rig (small), Marabou jig |
| Fall | 6 to 20 ft chart-limited; documented 8 to 22 ft | midday | Break off the point (7 ft) | Small tube jig, Inline spinner |
| Winter | 6 to 20 ft chart-limited; documented 12 to 30 ft | midday | Deep basin (20 ft) | Tungsten jig + plastic, Small spoon + spike |
When the water first warms, pumpkinseed slide up into 1 to 8 ft. By summer they slide out to 2 to 10 ft, and by winter most fish are in 6 to 18 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. In summer the feeding windows fall in the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Deep basin (20 ft) | Tungsten ice jig + plastic, Tiny spoon |
