25-acre lake in Algoma District, Ontario. The lake tops out around 32 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 25 acres, worked by 1 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 29% of this chart, as modeled. End to end it runs roughly 0.4 mi, about 0.2 mi across. It sits in Algoma District. Bouck L. 21 sits 0 mi east — the closest neighbouring chart.
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Summer pushes them deeper, 2 to 10 ft, and winter fish settle into 6 to 18 ft. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for pumpkinseed in spring. Warm-month bites cluster around the evening and early morning. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (4 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (4 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (4 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for brown bullhead tight to the bank in 2 to 8 ft. Expect a summer slide to 3 to 12 ft, then a winter hold in 10 to 25 ft. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. Prime time lands in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (4 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (4 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (4 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (27 ft) |
