Rating depth structure for splake.
Recent public catches load as you reach this section.
11-acre lake in Renfrew County, Ontario. The lake tops out around 64 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 1969, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
Drawn out, this is 11 acres of water rimmed by 0.8 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. 50% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.3 mi. The water lies in Renfrew County. Closest neighbour on DepthScout: Smith Lake, 1 mi southeast 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: splake in 5 to 25 ft. As the season builds they drop to 25 to 60 ft, wintering in 10 to 45 ft. Top water on the chart: Break off the point, a drop-off in the 17 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a trolled spoon at the thermocline or a white tube jig (deep) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (18 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Deep basin (55 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (17 ft) | Jigging spoon tipped with minnow head, Small white tube |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 55 ft.
