10-acre lake in Renfrew County, Ontario. The lake tops out around 25 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 1976, a decades-old survey (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Hardwood Lake runs 10 acres with 0.6 miles of edge. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. 80% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The water lies in Renfrew County. Closest neighbour on DepthScout: Donahue Long Lake, 1 mi northwest of here.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 20 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 25 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
3 pieces of structure are mapped here — Deep basin, around 20 ft, is the deepest of them.
