On the chart, Twin Lake, Carbon South draws 24 acres inside 0.9 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. 17% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.

When the water first warms, cutthroat trout slide up into 3 to 15 ft. By summer they slide out to 10 to 35 ft, and by winter most fish are in 10 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 31 ft that scores prime in summer. In summer the feeding windows fall in 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 (17 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (31 ft) | Trolled spoon (small), Inline spinner |

Spring puts splake in skinny water — 5 to 25 ft is the zone. Warm water sends them out to 25 to 60 ft; cold water stacks them in 10 to 45 ft. Break off the point is the standout, a drop-off at roughly 31 ft, rated prime for summer splake. Plan around early morning and the evening in the warm months. A trolled spoon at the thermocline or a white tube jig (deep) covers the summer program.
