Rating depth structure for rainbow trout.

6,078-acre lake near Fremont. The lake tops out around 18 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Species by species, here's what the data says the year looks like.
Drawn out, this is 6,151 acres of water rimmed by 19.4 miles of bank. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. About 86% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. End to end it runs roughly 6 mi, about 3.8 mi across. The water lies in Fremont County. The nearest mapped water is Elk Lake (Beaverhead), 12 mi to the west.
When the water first warms, cutthroat trout slide up into 3 to 15 ft. Summer is a 5 to 18 ft game here, winter a 5 to 18 ft one. Start at Break off the point. It's a drop-off holding about 8 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a trolled spoon (small) or an inline spinner rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Trolled spoon (small), Inline spinner |
| Fall | 4 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 5 to 18 ft | dawn | Break off the point (8 ft) | Small jigging spoon, Marabou jig |
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 5 to 18 ft; cold water stacks them in 3 to 18 ft. Gravel shoal is the standout, a gravel shoal at roughly 2 ft, rated prime for fall brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Gravel shoal (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 18 ft | dawn & dusk | Deep basin (15 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Gravel shoal (2 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 18 ft | dawn | Deep basin (15 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, rainbow trout run shallow here, mostly 5 to 18 ft. Summer keeps them at 5 to 18 ft, and they winter in 4 to 18 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 8 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 18 ft | dawn | Break off the point (8 ft) | Jigging spoon, Tube jig (white) |
