12-acre lake in Carbon County, Montana. The lake tops out around 30 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.
The chart traces 1.2 miles of shoreline here. A development index of 2.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 73% of the surface — that's where the groceries are. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. Carbon County claims this one. If the bite dies, Green Lake (Carbon) is 1 mi to the northeast.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 26 ft that scores prime in summer. Best bite is 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 | Main-lake point (9 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (26 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (9 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (15 ft) | Small jigging spoon, Tungsten jig + plastic |
