166-acre lake in Parry Sound District, Ontario. The lake tops out around 46 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 1979, a decades-old survey (an MNRF lake survey). What follows comes from the same scoring engine that paints the spots above.
Dogfish Lake maps at 168 acres behind 4.4 miles of shoreline. With a shoreline index of 2.4, this water is all arms and coves — edge habitat well beyond its acreage. 90% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 1.5 mi end to end and 0.5 mi across at its widest. Parry Sound District claims this one. Lac La Vallée sits 2 mi east — the closest neighbouring chart.
The spring pattern is a shallow one: cisco (lake herring) in 10 to 40 ft. Midsummer fish sit out in 14 to 46 ft before dropping to 14 to 46 ft for winter. The spot to know is Deep basin, a deep basin in about 36 ft of water that rates prime for cisco (lake herring) in spring. Plan around early morning in the warm months. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (36 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 14 to 46 ft | dawn | Deep basin (36 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (24 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 14 to 46 ft | dawn | Deep basin (36 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. The spot to know is Deep basin, a deep basin in about 36 ft of water that rates prime for yellow perch in fall. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| 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 | 10 to 30 ft | dawn | Break off the point (24 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (36 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (36 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 20 to 45 ft. Start at Break off the point. It's a drop-off holding about 24 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (3 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (24 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (24 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (24 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: pumpkinseed in 1 to 8 ft. Midsummer fish sit out in 2 to 10 ft before dropping to 6 to 18 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 1 ft of water that rates prime for pumpkinseed in spring. Plan around the evening and early morning in the warm months. Summer baits: a micro tube or a sponge spider (fly) gets it done.
| 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 | Shallow bay flat (1 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, brown bullhead slide up into 2 to 8 ft. Summer is a 3 to 12 ft game here, winter a 10 to 25 ft one. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. The feeding windows run after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (1 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (1 ft) | |
| Fall | 5 to 15 ft | dusk | open water | |
| Winter | 10 to 25 ft | midday | Deep basin (36 ft) |
