Lahontan Cutthroat Trout


Interpretation and Commentary

  • Relevance - The Lahontan cutthroat trout (LCT, Oncrhynchus clarkii henshawi), the only native trout in the Lake Tahoe Basin, was once a top predator in Lake Tahoe’s aquatic ecosystem. Due to overfishing, habitat degradation, and the introduction of non-native aquatic species it wasextirpated in the 1930s from Lake Tahoe Basin (Allen et al. 2003). It is currently listed as a 'threatened species' under the Federal Endangered Species Act (as amended).
  • Status – The Lahontan cutthroat trout Policy Statement has been “implemented” by TRPA and determined to be in “attainment” with the adopted Policy Statement. The Region could further be considered in “attainment” because a population of LCT has been established in the Upper Truckee River with additional restoration efforts underway to re-establish populations in Lake Tahoe and Fallen Leaf Lake.
