Rating depth structure for lake trout.

13-acre lake in Thunder Bay District, Ontario. The lake tops out around 60 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 season-by-season read for each species follows, from the map's own numbers.
The outline encloses 12 acres, worked by 0.7 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. About 65% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 0.3 mi. It sits in Thunder Bay District. If the bite dies, Fall Lake is 0 mi to the south.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Shoreline break. It's a drop-off holding about 3 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shoreline break (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Shoreline break (3 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 | Shoreline break (3 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring lake trout on Miner Lake hold shallow, usually 10 to 40 ft. By summer they slide out to 18 to 60 ft, and by winter most fish are in 15 to 60 ft. The chart's best answer is Deep basin — deep basin, 56 ft, prime for summer. Prime time lands in early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Shoreline break (3 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 18 to 60 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (56 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Shoreline break (3 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 15 to 60 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (56 ft) | White tube jig, Airplane jig |
4 pieces of structure are mapped here — Deep basin, around 56 ft, is the deepest of them.
Season dates, license requirements, and size and bag limits for Ontario waters are set by the Ontario fishing regulations (FMZ summary) — and special regulations can apply to Miner Lake specifically, so confirm the current rules before you fish.
