69-acre lake near Montana. The lake tops out around 25 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here is how the season plays out for each species, straight from the data behind the map.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. By summer they slide out to 7 to 25 ft, and by winter most fish are in 5 to 25 ft. The spot to know is Break off the point, a drop-off in about 20 ft of water that rates prime for rainbow trout in winter. Best bite is early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Go-to baits |
|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Inline spinner (silver), Small spoon |
| Summer | 7 to 25 ft | dawn & dusk | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 7 to 25 ft | dawn & dusk | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 25 ft | dawn | Jigging spoon, Tube jig (white) |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. They move out to 8 to 25 ft in summer and finish the year down in 8 to 25 ft. If you only fish one area, make it Back-bay flat: a weed flat around 7 ft that scores prime in spring. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Go-to baits |
|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 25 ft | dawn | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 25 ft | midday | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 25 ft | midday & dawn | Tungsten jig + spikes, Rattle spoon (small) |

Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
