Overview

Basics

Basics
Reintroduction and management of LCT continued in the Fallen Leaf Lake watershed in 2022 under a Memorandum of Understanding and a new scientific collection permit between FWS and CDFW. These agreements identify adaptive management priorities for establishing and protecting the lacustrine LCT population in the lake. Activities followed recommendations from the Science Panel Independent Review Report (Al-Chokhachy et al. 2020). The 2023 sampling season accomplishments included nonnative lake trout removal, installation of a fyke net, backpack electrofishing and stocking a total of 34,869 LCT.

12/14/2017 8:23 AM Stephanie Byers Lake Tahoe basin recovery planning and implementation for Lahontan cutthroat trout (LCT) has been led by the USFWS-Lahontan NFH Complex in collaboration with State, Tribal, agency and university partners since 2002. Reintroduction began as a research template for conservation measures to reestablish a selfsustaining lacustrine LCT into Lake Tahoe. 2008 strategies such as stocking smaller LCT numbers per site during the thermocline in areas with habitat complexity and managing impacts from nonnative lake trout provided niche space resulting in increased LCT overwintering survival. In 2012 LCT were documented spawning in Glen Alpine Creek for the first time in the Tahoe Basin in over 70 years.
08/02/2016 3:40 PM Stephanie Byers Lahontan cutthroat trout (LCT) restoration, recovery planning and implementation in the Tahoe basin has been led by the USFWS-Lahontan National Fish Hatchery Complex (LNFHC) in collaboration with our State, Tribal, agency, community and university partners since 2002. The LCT used in this reintroduction effort is the Pilot Peak strain, genetically representative of the original LCT found in the Lake Tahoe basin. Reintroduction of LCT in Fallen Leaf Lake was initiated as a template for research into conservation measures needed to re-establish a self-sustaining lacustrine form of LCT in Lake Tahoe. In 2008, stocking strategies such as stocking smaller numbers of fish per site, during periods of thermal stratification to minimize encounters with predators and in areas with habitat complexity were identified and implemented to improve stocking survival. These strategies as well as managing impacts from nonnative lake trout proved effective in providing a “niche” for reintroduced LCT resulting in increased survival of overwintering LCT in the lake. In 2012 for the first time in the Tahoe basin lacustrine LCT were documented spawning in Glen Alpine Creek. Since 2012 in coordination with our partners we have transitioned from a predominantly research program to an active adaptive management approach. We are focusing on efforts to continue improving LCT spawning, reproduction, and survival, minimizing hybridization with nonnative rainbow trout and increasing nonnative lake trout suppression in both Fallen Leaf Lake and the Glen Alpine Creek watershed.
In 2011 Lahontan National Fish Hatchery Complex, in collaboration with our partners in the Tahoe Basin and our researcher, University of Washington completed a two year study on a baseline pelagic food web study in Lake Tahoe. This study, the first comprehensive look at the current ecosystem, determined interactions between the different trophic levels including abundance of prey/predator species and interactions between predator/prey to assess possible restoration and reintroduction of Lahontan cutthroat trout (LCT). These findings were presented in 2015 to our partners on the Tahoe Basin Recovery Implementation Team (RIT), researchers in the basin, and the public including the Douglas County Advisory Board to Manage Wildlife. Further studies were identified to increase our understanding of lake trout spawning and self-regulating recruitment that potentially will increase successful reintroduction of LCT into Lake Tahoe.
The LCT reintroduction project in the Tahoe basin contributes to the achievement of both fisheries and recreation environmental thresholds. For fisheries it improves in-lake and in-stream habitats by managing nonnative fish to improve habitat utilization by LCT, listed amphibians, and other native species. These objectives are being accomplished in the Glen Alpine Creek watershed (~ 8 miles) and will be initiated in 2-5 high priority tributaries to Lake Tahoe (~ 20 miles). Aquatic resources such as zooplankton and fishes both native and nonnative were monitored and sampled to establish a baseline pelagic food web in Lake Tahoe (49,728 ha). Additionally, recovery and restoration of lacustrine LCT provides a recreational fishing experience for native trout species in both Fallen Leaf Lake and Glen Alpine Creek. Fallen Leaf Lake provides a near-shore native lacustrine fishery that has not been available for more than 10 years in this basin.
