Lahontan Cutthroat Trout
Nevada’s native cutthroat links icy headwaters with Pyramid Lake, carrying the history of an immense Ice Age watershed in one living fish.

Lahontan Cutthroat Trout evolved across the Lahontan basin and include lake and stream forms with strikingly different growth. Pyramid Lake historically produced enormous fish because cui-ui and other prey supported a top predator; dams, diversions, invasive species, and lost passage drove severe decline before restoration and reintroduction.
Look from shore without trampling spawning tributaries, or fish only under the exact license, permit, tackle, season, and retention rules for that water. At Pyramid Lake, Tribal regulations govern access. Identification should combine spotting pattern and throat slash with location because stocked rainbow trout and hybrids can complicate appearance.

Field evidence for Lahontan Cutthroat Trout
- Establish structure
- Treat “Cutthroat slash” as a field hypothesis.
- Challenge the first view
- After the overall form, confirm Tailward black spotting.
- Check when and where

- Observe Lahontan Cutthroat Trout from a stable bank or platform where possible, without entering spawning cover or disturbing sediment.
Good to know
There is no single statewide fishing rule for this trout. Pyramid Lake requires Tribal permits, some recovery waters are closed, and other streams have special tackle or harvest limits; confirm the exact water before casting.
