The spring pattern is a shallow one: lake trout in 10 to 40 ft. Midsummer fish sit out in 16 to 53 ft before dropping to 13 to 53 ft for winter. The spot to know is Deep basin, a deep basin in about 51 ft of water that rates prime for lake trout in summer. Plan around early morning in the warm months. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Break off the point (18 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 40 ft. The spot to know is Break off the point, a drop-off in about 18 ft of water that rates prime for rainbow trout in winter. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.

If you only fish one area, make it Deep basin: a deep basin around 51 ft that scores prime in summer. Best bite is early morning.
