Rating depth structure for rainbow trout.

82-acre lake in Timiskaming District, Ontario. The lake tops out around 37 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. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Weldy Lake draws 82 acres inside 2.9 miles of shoreline. That shoreline is heavily fingered (development index 2.3) — bays, points and pockets everywhere, which multiplies the fishable edge. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 0.8 mi, about 0.4 mi across. The water lies in Timiskaming District. Closest neighbour on DepthScout: Steve Lake, 1 mi west of here.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 7 to 37 ft for winter. The spot to know is Deep basin, a deep basin in about 21 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| 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 |
| Summer | 8 to 30 ft | dawn & dusk | Deep basin (21 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Deep basin (21 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 37 ft | dawn | Deep basin (21 ft) | Jigging spoon, Tube jig (white) |
6 pieces of structure are mapped here — Deep basin, around 21 ft, is the deepest of them.
