8-acre lake in Nipissing District, Ontario. The lake tops out around 20 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 1968, a decades-old survey (an MNRF lake survey). Species by species, here's what the data says the year looks like.
Traced from the shoreline, Round Lake runs 7 acres with 0.4 miles of edge. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. The shallow band under 15 ft claims about 84% of the surface — that's where the groceries are. The water lies in Nipissing District. The nearest mapped water is Shanty Lake, 1 mi to the southwest.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 6 to 20 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 | Shallow bay flat (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 20 ft | dawn & dusk | Deep basin (20 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 | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
