84-acre lake in Carbon County, Montana. The lake tops out around 225 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.
The drawn water covers 101 acres wrapped in 2 miles of bank. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 4% of this chart. Figure 0.7 mi of water from one end to the other, 0.3 mi at the beam. It sits in Carbon County. If the bite dies, Shelf Lake is 1 mi to the southwest.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Main-lake point: a point around 18 ft that scores good in spring. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (18 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (18 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | open water | Small jigging spoon, Tungsten jig + plastic |
