506-acre lake near Lander Region. The lake tops out around 275 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 487 acres wrapped in 6 miles of bank. A middling shoreline index (1.9) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 16% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 2.2 mi with a 0.7-mi widest point. Fremont County claims this one. Upper Ross Lake sits 2 mi south — the closest neighbouring chart.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 6 ft that scores good in spring. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow bay flat (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (124 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: cutthroat trout sit in 3 to 15 ft that time of year. Summer pushes them deeper, 10 to 35 ft, and winter fish settle into 10 to 40 ft. The spot to know is Break off the point, a drop-off in about 124 ft of water that rates good for cutthroat trout in summer. Warm-month bites cluster around early morning and the evening. Throw a trolled spoon (small) or an inline spinner until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
