16-acre lake in Renfrew County, Ontario. The lake tops out around 36 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1985 (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 16 acres of water rimmed by 0.6 miles of bank. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. About 68% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The water lies in Renfrew County. Closest neighbour on DepthScout: Soldier Lake, 1 mi northwest of here.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Shoreline break, a drop-off in about 10 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Shoreline break (10 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shoreline break (10 ft) | Small jigging spoon, Tungsten jig + plastic |
