32-acre lake in Park County, Montana. The lake tops out around 70 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 drawn water covers 36 acres wrapped in 1.3 miles of bank. A middling shoreline index (1.6) gives it some bays to work without being a maze. About 22% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.6 mi of water from one end to the other, 0.2 mi at the beam. Park County claims this one. If the bite dies, Glacier Green Lake is 2 mi to the south.
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 Shallow bay flat: a weed flat around 11 ft that scores good in spring. 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 | Shallow bay flat (11 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (37 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (11 ft) | Small jigging spoon, Tungsten jig + plastic |
5 pieces of structure are mapped here — Deep basin, around 66 ft, is the deepest of them.
