40-acre lake near Cody Region. The lake tops out around 28 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Here's the year, species by species, as the scoring engine sees it.
Shoreline on the chart totals 0.8 miles. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. About 27% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. The water lies in Park County. For a second option, Lower Sheepherder Lake lies 0 mi southeast.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 3 to 20 ft for winter. The spot to know is Deep basin, a deep basin in about 24 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 28 ft | dawn & dusk | Deep basin (24 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (13 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 24 ft.
