226-acre lake in Sudbury District, Ontario. The lake tops out around 52 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 1958, a decades-old survey (an MNRF lake survey). Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Hamilton Lake runs 228 acres with 3.9 miles of edge, broken up by an island. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. The shallow band under 15 ft claims about 94% of the surface — that's where the groceries are. Tip to tip the water measures near 0.9 mi with a 0.7-mi widest point. The water lies in Sudbury District. Closest neighbour on DepthScout: Stripcut L., 1 mi northeast of here.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 24 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (24 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (2 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. Winter rainbow trout concentrate at Deep basin, a prime-rated deep basin around 24 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (1 ft) | Inline spinner (silver), Small spoon |
