40-acre lake near Cody Region. The lake tops out around 120 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Species by species, here's what the data says the year looks like.
Drawn out, this is 41 acres of water rimmed by 1.1 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 8% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 0.3 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in Park County. The nearest mapped water is Wall Lake, 1 mi to the west.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | open water | 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 | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | open water | Small jigging spoon, Tungsten jig + plastic |
