141-acre lake in Haliburton County, Ontario. The lake tops out around 20 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What the data behind the map says about each species, season by season:
The outline encloses 142 acres, worked by 2.6 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. Roughly 83% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 0.9 mi with a 0.4-mi widest point. It sits in Haliburton County. If the bite dies, White Trout Bay is 1 mi to the northeast.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 6 to 20 ft before dropping to 6 to 20 ft for winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| 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 | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. Summer is a 6 to 20 ft game here, winter a 6 to 20 ft one. Start at Break off the point. It's a drop-off holding about 2 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 6 to 20 ft | dawn & dusk | Break off the point (2 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 20 ft | midday & dawn | Main-lake point (1 ft) | Jerkbait, Blade bait |
| Winter | 6 to 20 ft | midday | Break off the point (2 ft) | Blade bait, Hair jig |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 6 to 20 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (1 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) | Blade bait, Jigging spoon |
Start shallow in spring: rock bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 5 to 20 ft, and winter fish settle into 6 to 20 ft. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for rock bass in winter. Warm-month bites cluster around the evening. Throw a ned rig (small) or a marabou jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (1 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (1 ft) | Ned rig (small), Marabou jig |
| Fall | 6 to 20 ft | midday | Break off the point (2 ft) | Small tube jig, Inline spinner |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) | Tungsten jig + plastic, Small spoon + spike |
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 1 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 (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 |
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 6 to 20 ft. Start at Deep basin. It's a deep basin holding about 20 ft of water and rates prime come winter. 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 (1 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (1 ft) | |
| Fall | 5 to 15 ft | dusk | open water | |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) |
Deer Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 20 ft down.

Anglers target yellow perch, smallmouth bass, largemouth bass, rock bass, pumpkinseed, brown bullhead on Deer Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species Ontario's MNRF recorded in the nearest surveyed lakes, filtered to this lake's depth and habitat.
Deep basin is the top-rated area: a deep basin in about 20 ft of water that rates prime for yellow perch in fall. The map above holds the full rated-spot list for every species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
