190-acre lake near Lander Region. The lake tops out around 178 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. What the data behind the map says about each species, season by season:
On the chart, Upper Ross Lake draws 186 acres inside 3.4 miles of shoreline. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. The shallow band under 15 ft claims about 22% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 1.4 mi with a 0.4-mi widest point. The water lies in Fremont County. The nearest mapped water is Lower Ross Lake, 2 mi to the north.
Come spring, look for cutthroat trout tight to the bank in 3 to 15 ft. They move out to 10 to 35 ft in summer and finish the year down in 10 to 40 ft. If you only fish one area, make it Main-lake point: a point around 45 ft that scores good in winter. Best bite is early morning and the evening. A trolled spoon (small) or an inline spinner is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | open water | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (80 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (45 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Main-lake point (45 ft) | Small jigging spoon, Marabou jig |
