26-acre lake in Haliburton County, Ontario. The lake tops out around 10 ft. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 26 acres of water rimmed by 1.1 miles of bank. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. The water lies in Haliburton County. The nearest mapped water is Lower Welch Lake, 0 mi to the southwest.
Spring puts smallmouth bass in skinny water — 3 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 3 to 10 ft. Fall smallmouth bass concentrate at Main-lake point, a prime-rated point around 6 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | dawn & dusk | Main-lake point (6 ft) | Ned rig, Tube jig |
| Summer | 3 to 10 ft | dawn & dusk | Break off the point (9 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 3 to 10 ft | midday & dawn | Main-lake point (6 ft) | Jerkbait, Blade bait |
| Winter | 3 to 10 ft | midday | Break off the point (9 ft) | Blade bait, Hair jig |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 3 to 10 ft. Main-lake point is the standout, a point at roughly 6 ft, rated prime for fall largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Main-lake point (6 ft) | Spinnerbait, Chatterbait |
| Summer | 3 to 10 ft | dawn & dusk | Break off the point (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 10 ft | midday & dawn | Main-lake point (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 3 to 10 ft | midday | Break off the point (9 ft) | Blade bait, Jigging spoon |
When the water first warms, pumpkinseed slide up into 1 to 8 ft. By summer they slide out to 2 to 10 ft, and by winter most fish are in 3 to 10 ft. If you only fish one area, make it Deep basin: a deep basin around 10 ft that scores prime in winter. In summer the feeding windows fall in the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | open water | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 3 to 10 ft | dusk & dawn | Break off the point (9 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 10 ft | dawn | Deep basin (10 ft) | Tungsten ice jig + plastic, Tiny spoon |
