10-acre reservoir near Green River Region. The lake tops out around 19 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, J O Reservoir draws 11 acres inside 0.7 miles of shoreline. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 64% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 0.3 mi. You'll find it in Carbon County. For a second option, Rawlins City Res lies 13 mi east.
The spring pattern is a shallow one: rainbow trout in 5 to 19 ft. The depth story barely changes: 5 to 19 ft through summer, 4 to 19 ft in winter. Top water on the chart: Break off the point, a drop-off in the 9 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 19 ft | dawn & dusk | Break off the point (9 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 19 ft | dawn | Break off the point (9 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 6 to 19 ft, and winter fish settle into 3 to 19 ft. The spot to know is Deep basin, a deep basin in about 16 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
