26-acre lake in Beaverhead County, Montana. The lake tops out around 33 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. Here's the year, species by species, as the scoring engine sees it.
The drawn outline gives you 2.3 miles of bank to pick apart. The 2.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. 74% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 0.6 mi end to end and 0.3 mi across at its widest. It sits in Beaverhead County. Van Houten Lake sits 7 mi southeast — the closest neighbouring chart.
Spring brook trout on Lower Miner Lakes hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Break off the point — drop-off, 19 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (19 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (19 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring arctic grayling on Lower Miner Lakes hold shallow, usually 2 to 10 ft. By summer they slide out to 3 to 15 ft, and by winter most fish are in 8 to 25 ft. The chart's best answer is Break off the point — drop-off, 19 ft, prime for fall. Prime time lands in the evening and early morning. The summer box starts with a dry fly (parachute adams, elk hair caddis) or a small inline spinner.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dusk | Shallow bay flat (9 ft) | 1/16 oz spinner (silver), Small dry fly (Adams, Griffith's) |
| Summer | 3 to 15 ft | dusk & dawn | Shallow bay flat (9 ft) | Dry fly (parachute Adams, elk hair caddis), Small inline spinner |
| Fall | 6 to 20 ft | midday | Break off the point (19 ft) | Small spoon, Beadhead nymph under indicator |
| Winter | 8 to 25 ft | midday & dawn | Break off the point (19 ft) | Tungsten jig + waxworm, Small jigging spoon (gold) |
Come spring, look for burbot tight to the bank in 10 to 33 ft. Through summer count on 10 to 33 ft; the winter hold is 8 to 33 ft. Start at Deep basin. It's a deep basin holding about 33 ft of water and rates prime come spring. Prime time lands in after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 33 ft | night & dusk | Deep basin (33 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 10 to 33 ft | night & midday | Deep basin (33 ft) | Heavy jig + cut bait |
| Fall | 10 to 33 ft | night & dusk | Deep basin (33 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 8 to 33 ft | night & dusk | Deep basin (33 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. Warm water sends them out to 9 to 33 ft; cold water stacks them in 8 to 33 ft. Break off the point is the standout, a drop-off at roughly 19 ft, rated prime for summer cutthroat trout. Plan around early morning and the evening in the warm months. A trolled spoon (small) or an inline spinner covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (10 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 9 to 33 ft | dawn & dusk | Break off the point (19 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon, Inline spinner |
| Winter | 8 to 33 ft | dawn | Break off the point (19 ft) | Small jigging spoon, Marabou jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 7 to 33 ft. Put Break off the point first on the milk run — a drop-off near 19 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (10 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (19 ft) | Dodger + spoon (deep troll), Flutter spoon |
