21-acre lake in Stillwater County, Montana. The lake tops out around 50 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. Species by species, here's what the data says the year looks like.
Drawn out, this is 23 acres of water rimmed by 1.3 miles of bank. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 27% of this chart. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. You'll find it in Stillwater County. Closest neighbour on DepthScout: Froze To Death Lake (Stillwater), 1 mi southwest of here.
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 36 ft of water and rates prime 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 (36 ft) | Trolled spoon (small), Inline spinner |
