37-acre lake in Renfrew County, Ontario. The lake tops out around 40 ft. The depth data here comes from the Ontario MNRF survey of 1971, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
The outline encloses 37 acres, worked by 1.4 miles of shoreline, with a single island in the mix. With a 1.7 development index there's bank structure worth casting at, in moderation. Roughly 31% of the water is 15 ft or less, the band where the food chain lives. Call it 0.4 mi long by 0.3 mi wide at the broadest reach. Renfrew County claims this one. If the bite dies, Bark Lake is 2 mi to the southwest.
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 12 to 40 ft. Start at Secondary point. It's a point holding about 9 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (5 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (26 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Secondary point (9 ft) | Jerkbait, Blade bait |
| Winter | 12 to 40 ft | midday | Break off the point (26 ft) | Blade bait, Hair jig |
