544-acre lake in Haliburton County, Ontario. The lake tops out around 120 ft. The depth data here comes from the Ontario MNRF survey of 1973, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
The outline encloses 546 acres, worked by 5.9 miles of shoreline, broken up by an island. With a 1.8 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 14% of this chart. The basin spans about 1.8 mi end to end and 0.9 mi across at its widest. Haliburton County claims this one. Clement Lake sits 1 mi south — the closest neighbouring chart.
When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 50 to 120 ft game here, winter a 20 to 80 ft one. Start at Deep basin. It's a deep basin holding about 120 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Secondary point (19 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (120 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Secondary point (19 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (120 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Shallow bay flat, a feeding flat in the 10 ft range, prime in spring. Time it for early morning. 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 (10 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (120 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (120 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 20 to 45 ft. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in fall. In summer the feeding windows fall in 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 (8 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Secondary point (19 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (120 ft) | Blade bait, Hair jig |
Start shallow in spring: rock bass sit in 2 to 10 ft that time of year. Warm water sends them out to 5 to 20 ft; cold water stacks them in 12 to 30 ft. Top water on the chart: Main-lake point, a point in the 8 ft range, prime in summer. Fish it in the evening and you'll meet the bite. 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 (8 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (8 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Main-lake point (8 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Deep basin (120 ft) | Tungsten jig + plastic, Small spoon + spike |
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Warm water sends them out to 2 to 10 ft; cold water stacks them in 6 to 18 ft. Top water on the chart: Back-bay flat, a feeding flat in the 3 ft range, prime in spring. Fish it in the evening and early morning and you'll meet the bite. 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 | Back-bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (10 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (10 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (10 ft) | Tungsten ice jig + plastic, Tiny spoon |
