64-acre lake in Haliburton County, Ontario. The lake tops out around 50 ft. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 64 acres, worked by 1.8 miles of shoreline, with a single island in the mix. With a 1.6 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 53% of this chart. Tip to tip the water measures near 0.5 mi with a 0.3-mi widest point. Haliburton County claims this one. Little Harburn Lake sits 1 mi north — the closest neighbouring chart.
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: Shallow bay flat, a weed flat in the 5 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 | Shallow bay flat (5 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (5 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Back-bay flat (7 ft) | Tungsten ice jig + plastic, Tiny spoon |
6 pieces of structure are mapped here — Deep basin, around 49 ft, is the deepest of them.
