91-acre lake in Renfrew County, Ontario. The lake tops out around 66 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 92 acres of water rimmed by 2.6 miles of bank, with a single island in the mix. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. The shallow band under 15 ft claims about 37% of the surface — that's where the groceries are. Tip to tip the water measures near 0.7 mi with a 0.5-mi widest point. You'll find it in Renfrew County. The nearest mapped water is Moor Lake, 1 mi to the east.
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Back-bay flat: a weed flat around 5 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Back-bay flat (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (44 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (66 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Secondary point (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Back-bay flat (5 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (5 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 15 to 35 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for largemouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Secondary point (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Secondary point (9 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (44 ft) | Blade bait, Jigging spoon |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 10 to 25 ft for winter. Spring brown bullhead concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Fish it in after dark and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (2 ft) | |
| Summer | 3 to 12 ft | night & dusk | Back-bay flat (5 ft) | |
| Fall | 5 to 15 ft | dusk | Back-bay flat (5 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (66 ft) |
