13-acre lake in Park County, Montana. The lake tops out around 100 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. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Wrong Lake runs 17 acres with 0.7 miles of edge. Nearly circular (index 1.3), so the story is the bottom, not the bank. 6% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.3 mi. You'll find it in Park County. For a second option, Courthouse Lake lies 1 mi southeast.
Come spring, look for cutthroat trout tight to the bank in 3 to 15 ft. Expect a summer slide to 10 to 35 ft, then a winter hold in 10 to 40 ft. Start at Break off the point. It's a drop-off holding about 85 ft of water and rates good come summer. Prime time lands in early morning and the evening. A trolled spoon (small) or an inline spinner is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | open water | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (85 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (52 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (85 ft) | Small jigging spoon, Marabou jig |
