139-acre lake in Parry Sound District, Ontario. The lake tops out around 23 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 1985 (an MNRF lake survey). Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Bittern Lake draws 139 acres inside 2.4 miles of shoreline. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. 97% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 0.8 mi end to end and 0.5 mi across at its widest. You'll find it in Parry Sound District. The nearest mapped water is Haller Lake, 1 mi to the south.
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 7 to 23 ft in summer and finish the year down in 7 to 23 ft. If you only fish one area, make it Deep basin: a deep basin around 20 ft that scores prime in fall. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| 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 | 7 to 23 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 23 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 23 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 7 to 23 ft; cold water stacks them in 7 to 23 ft. Top water on the chart: Break off the point, a drop-off in the 12 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Secondary point (3 ft) | Ned rig, Tube jig |
| Summer | 7 to 23 ft | dawn & dusk | Break off the point (12 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 7 to 23 ft | midday & dawn | Break off the point (12 ft) | Jerkbait, Blade bait |
| Winter | 7 to 23 ft | midday | Break off the point (12 ft) | Blade bait, Hair jig |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. Best bite is the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.
| 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 |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 7 to 23 ft for winter. Winter brown bullhead concentrate at Deep basin, a prime-rated deep basin around 20 ft. Fish it in after dark and the evening and you'll meet the bite.
| 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 | 7 to 23 ft | midday | Deep basin (20 ft) |
