44-acre lake in Parry Sound District, Ontario. The lake tops out around 16 ft. The depth data here comes from the Ontario MNRF survey of 1974, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
Little Butt Lake maps at 44 acres behind 2 miles of shoreline. With a shoreline index of 2.2, this water is all arms and coves — edge habitat well beyond its acreage. Tip to tip the water measures near 0.7 mi with a 0.3-mi widest point. It sits in Parry Sound District. Its nearest charted neighbour, Dewfish Lake, is 2 mi to the east.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 5 to 16 ft, then a winter hold in 2 to 16 ft. Start at Deep basin. It's a deep basin holding about 15 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 16 ft | dawn & dusk | Deep basin (15 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 16 ft | dawn | Deep basin (15 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 5 to 16 ft before dropping to 5 to 16 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 16 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 16 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Summer is a 5 to 16 ft game here, winter a 5 to 16 ft one. The chart's best answer is Main-lake point — point, 2 ft, prime for fall. Best bite is early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 5 to 16 ft | dawn & dusk | Break off the point (2 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 16 ft | midday & dawn | Main-lake point (2 ft) | Jerkbait, Blade bait |
| Winter | 5 to 16 ft | midday | Break off the point (2 ft) | Blade bait, Hair jig |
In spring, pumpkinseed run shallow here, mostly 1 to 8 ft. Summer pushes them deeper, 2 to 10 ft, and winter fish settle into 5 to 16 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring pumpkinseed. Time it for the evening and early morning. You won't need more than a micro tube or a sponge spider (fly) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 16 ft | dawn | Deep basin (15 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season brown bullhead use the shallows, holding in 2 to 8 ft. Expect a summer slide to 3 to 12 ft, then a winter hold in 5 to 16 ft. Put Deep basin first on the milk run — a deep basin near 15 ft that grades prime for winter. 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 (3 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 5 to 15 ft | dusk | Deep basin (15 ft) | |
| Winter | 5 to 16 ft | midday | Deep basin (15 ft) |
