The goal of NFWF's Lahontan Cutthroat Trout initiative was to protect existing pure populations from contact with non-native trout, sustain Lahontan cutthroat populations in lakes, connect isolated populations into larger, more resilient populations, and increase Lahontan cutthroat angling opportunities.
Lahontan cutthroat trout have a long evolutionary history in the Great Basin (NV, UT) and are highly distinct from other sub-species of cutthroat trout. Historically, they was found in a wide array of stream and river systems as well as freshwater and alkaline lakes. As a result of this diverse habitat, Lahontan cutthroat developed a variety of life histories, including resident stream, migratory and lake-dwelling forms.
For over a decade, the Lahontan Cutthroat Trout initiative helped to secure existing populations of Lahontan cutthroats, establish new populations, and connect isolated populations to enhance long-term resilience of these fish to environmental disruptions like fire and drought. NFWF grant partners removed invasive species from 350 miles of stream and have conducted extensive genetic and population monitoring to enable ongoing management of secured populations.
NFWF closed its Lahontan Cutthroat Trout Business Plan in 2020 and is currently supporting partners in documenting lessons learned throughout the past 10 years and completing final steps toward sustainable management of the population gains achieved to date.

Cutthroat trout
Cutthroat trout (Oncorhynchus clarkii) encompasses a number of distinct trout subspecies. These are iconic denizens of western landscapes, known for the red "cutthroat" under their jaw. They are associated with cold, clean, highly oxygenated streams, though many of the forms live in lakes and one is anadromous. Cutthroat trout are impacted by stream barriers, invasive fish and de-watering of their habitat.
Lahontan cutthroat trout
The Lahontan cutthroat trout is a distinct species of cutthroat trout, native to cold-water habitats throughout the Lahontan Basin of northern Nevada, eastern California, and southern Oregon. Lahontan cutthroat trout have been listed as “threatened” under the Endangered Species Act since 1975, with key threats identified as habitat fragmentation and degradation that have led to genetic isolation and increased competition.
