15-acre lake near Cody Region. The lake tops out around 31 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What the data behind the map says about each species, season by season:
The outline encloses 14 acres, worked by 0.9 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 44% of this chart, as modeled. Figure 0.3 mi of water from one end to the other. It sits in Park County. Mutt Lake sits 0 mi west — the closest neighbouring chart.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 26 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.

|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 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 |
