7-acre reservoir near Rio Blanco County. 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. Below is the species-by-species picture, pulled from the same data the map uses.
Shoreline on the chart totals 1.1 miles. Nearly circular (index 1.3), so the story is the bottom, not the bank. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 0.4 mi, about 0.2 mi across. Rio Blanco County claims this one. If the bite dies, Trappers Lake is 12 mi to the southwest.
The spring pattern is a shallow one: brown trout in 1 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 1 to 10 ft in winter. Top water on the chart: Break off the point, a drop-off in the 5 ft range, prime in summer. Time it for after dark and early morning. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 3 to 10 ft | night & dawn | Break off the point (5 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 2 to 10 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 10 ft | dawn | Break off the point (5 ft) | Jigging spoon, Small stickbait (slow) |
The spring pattern is a shallow one: cutthroat trout in 2 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 3 to 10 ft in winter. Top water on the chart: Break off the point, a drop-off in the 5 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a trolled spoon (small) or an inline spinner gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 3 to 10 ft | dawn & dusk | Break off the point (5 ft) | Trolled spoon (small), Inline spinner |
| Fall | 2 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 3 to 10 ft | dawn | Break off the point (5 ft) | Small jigging spoon, Marabou jig |
When the water first warms, rainbow trout slide up into 3 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 2 to 10 ft. Start at Break off the point. It's a drop-off holding about 5 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 3 to 10 ft | dawn & dusk | Break off the point (5 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 3 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 2 to 10 ft | dawn | Break off the point (5 ft) | Jigging spoon, Tube jig (white) |
