22-acre lake in Cochrane District, Ontario. The lake tops out around 40 ft. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
There are 0.7 miles of drawn shoreline to work. Nearly circular (index 1.3), so the story is the bottom, not the bank. 31% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 0.3 mi end to end. It sits in Cochrane District. Camp Lake sits 3 mi south — the closest neighbouring chart.
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 30 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (15 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (30 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (30 ft) | Jigging rap, Jig + big minnow |

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Break off the point is the standout, a drop-off at roughly 30 ft, rated prime for summer yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (30 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

The summer box starts with a bucktail or a weedless spoon over cabbage.
