5-acre lake near Cody Region. The lake tops out around 10 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 6 acres, worked by 0.5 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. It sits in Big Horn County. If the bite dies, Lower Rainbow Lake is 0 mi to the southwest.
When the water first warms, brook trout slide up into 1 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 2 to 10 ft. If you only fish one area, make it Deep basin: a deep basin around 9 ft that scores prime in summer. 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 | 1 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 3 to 10 ft | dawn & dusk | Deep basin (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 10 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 10 ft | dawn | Deep basin (9 ft) | Small jigging spoon, Tungsten jig + plastic |
