Description

Lake Tahoe and adjacent lakes face a constant and serious threat from the introduction and spread of aquatic invasive species (AIS). AIS degrades water quality, degrades natural fish habitat and can affect the recreation opportunities that drive Lake Tahoe’s economy. Since 2008, the nationally recognized Watercraft Inspection Program has prevented new AIS from entering the lake.  The program calls for inspection of all motorized watercraft to ensure new AIS are not introduced. To control and eradicate existing AIS populations in the lake and, resource managers are implementing AIS control projects, testing new technologies and actively engaging with marinas and homeowners.

 

The AIS Control Action Agenda implements a suite of AIS control actions through the next decade to reduce the economic, environmental, and social effects of AIS in the Lake Tahoe Region. The Agenda describes a 10-year (2021–2030) two-phased effort. Phase 1 (2021–2025) aggressively treats and controls AIS throughout the Region for five consecutive years while containing AIS and completing AIS control planning for the Tahoe Keys. Phase II (2026–2030) focuses efforts on reducing aquatic invasive plants and invasive fish in the Tahoe Keys while continuing to maintain, reduce, or eradicate AIS in other parts of the Lake Tahoe Region.

Lake Tahoe Aquatic Invasive Species Management Plan

Lake Tahoe already hosts several aquatic invasive species. TRPA leads a collaborative effort to control existing invasive species, which costs millions of dollars every year. The Lake Tahoe Aquatic Invasive Species Management Plan aims to: prevent new introductions of AIS in Tahoe, limit the spread of existing AIS populations, employ strategies to minimize threats to native species, and extirpate existing AIS populations, abate harmful ecological, economic, social, and public health impacts.

2015 Implementation Plan for the Control of Aquatic Invasive Species within Lake Tahoe

Once invasive species enter the ecosystem they crowd out native populations, impair habitats and water quality, and reduce recreational opportunities. TRPA oversees projects that reduce and eradicate populations of invasive aquatic weeds, asian clams, non-native fish, bullfrogs, or other identified species. Projects also include pilot projects and the rapid response to new locations of AIS infestations to prevent further spread.
