Overview
Basics
Basics
Tributary management is an essential component of Lahontan cutthroat trout (LCT) reintroduction in Lake Tahoe. A previous effort by the Tahoe Basin LCT Recovery Implementation Team collectively evaluated and prioritized tributaries in the basin with potential to support recovery of LCT. These tributaries will be assessed for the establishment of a temporary fish passage barrier (weir) and data collected will be used to inform development of a tributary management plan. In 2022 the LNFHC continued development and testing of a field protocol to rate potential fish passage barrier sites near the confluence with Lake Tahoe. Barriers seek to minimize hybridization of LCT with nonnatives.

Threshold Categories
-
This project will delineate high priority tributaries for LCT spawning. Reproduction of LCT is necessary for building a self-sustaining population in the basin. Re-establishing this native top predator will be crucial for restoring a native ecosystem. A native species composition will have important benefits for the Lake Tahoe ecosystem such as increased water clarity and resistance to AIS reintroductions.
-
As the only native trout to the basin, LCT will provide a diverse, recreational angling experience. Identifying and managing high priority spawning tributaries will increase recreational opportunities by enhancing LCT numbers in the basin. Additionally, this iconic species provides unique viewing opportunities especially during their spring spawning runs. They are readily seen and caught from the near shore, providing those without boat access an opportunity to fish for the largest inland cutthroat trout in its native habitat.
-
LCT are the only trout native to the Tahoe basin. Historically these fish provided an important food source for native avian and terrestrial wildlife such as nesting Bald eagles and black bears.

| 01/11/2024 3:50 PM | Roy Ulibarri | In 2023 The USFWS completed field protocols and carried out 8 barrier and fish passage assessments with habitat assessments planned for 2024. Habitat assessments were not completed due to high flows from the extensive snow pack late into the season. | ||
| 01/13/2023 3:08 PM | Roy Ulibarri | In 2022 The USFWS continued development and field testing of a protocols to assess Lake Tahoe tributaries. Multiple barrier and fish passage assessments were completed as part of protocol development. | ||
