64-acre lake in Algoma District, Ontario. The lake tops out around 33 ft. The depth data here comes from the Ontario MNRF survey of 1985 (a transect sounding survey). What the data behind the map says about each species, season by season:
The outline encloses 65 acres, worked by 1.9 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. 43% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 0.5 mi end to end and 0.4 mi across at its widest. It sits in Algoma District. Little Duck Lake sits 0 mi east — the closest neighbouring chart.
When the water first warms, bluegill slide up into 1 to 6 ft. By summer they slide out to 4 to 15 ft, and by winter most fish are in 10 to 25 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (6 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (33 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, brown bullhead slide up into 2 to 8 ft. By summer they slide out to 3 to 12 ft, and by winter most fish are in 10 to 25 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores prime in spring. In summer the feeding windows fall 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 (6 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (6 ft) | |
