402-acre reservoir in Powell County, Montana. The lake tops out around 65 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What the data behind the map says about each species, season by season:
Traced from the shoreline, Nevada Reservoir runs 402 acres with 4 miles of edge. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. About 24% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 1.8 mi end to end and 0.4 mi across at its widest. The water lies in Powell County. For a second option, Browns Lake lies 15 mi northwest.
Spring yellow perch on Nevada Reservoir hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Back-bay flat — weed flat, 8 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (8 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (22 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (22 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (22 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season cutthroat trout use the shallows, holding in 3 to 15 ft. Summer is a 10 to 35 ft game here, winter a 10 to 40 ft one. The chart's best answer is Break off the point — drop-off, 22 ft, prime for summer. Best bite is early morning and the evening. Tie on a trolled spoon (small) or an inline spinner and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (22 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Secondary point (12 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (22 ft) | Small jigging spoon, Marabou jig |
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 22 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. 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 20 ft | dawn & dusk | Secondary point (12 ft) | Inline spinner (silver), Small spoon |
