39-acre lake in Renfrew County, Ontario. The lake tops out around 25 ft. The depth data here comes from the Ontario MNRF survey of 1969, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 39 acres of water rimmed by 1.3 miles of bank. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. The shallow band under 15 ft claims about 75% of the surface — that's where the groceries are. The basin spans about 0.5 mi end to end and 0.2 mi across at its widest. The water lies in Renfrew County. Closest neighbour on DepthScout: Roney Lake, 2 mi south of here.
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 8 to 25 ft. The spot to know is Break off the point, a drop-off in about 23 ft of water that rates prime for smallmouth bass in winter. Warm-month bites cluster around early morning and the evening. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (6 ft) | Ned rig, Tube jig |
| Summer | 8 to 25 ft | dawn & dusk | Break off the point (23 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (23 ft) | Jerkbait, Blade bait |
| Winter | 8 to 25 ft | midday | Break off the point (23 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. As the season builds they drop to 8 to 20 ft, wintering in 8 to 25 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
