TRUCKEE, Calif.  The Biden-Harris administration announced that the Department of the Interior’s U.S. Fish and Wildlife Service has awarded $3.4 million in funding from President Biden’s Bipartisan Infrastructure Law for cooperative agreements with the Washoe Tribe of California and Nevada and the Tahoe Regional Planning Agency to combat the spread of aquatic invasive species in Lake Tahoe. 

The funding represents a historic effort dedicated to restoring the Lake Tahoe Basin ecosystem and emphasizes the Administration’s commitment to inclusive engagement with Tribes, partners and stakeholders. 

“Along with continued boater education, adding permanent watercraft inspection stations will strengthen protection of Lake Tahoe from further introductions of aquatic invasive species, which could severely harm the region’s delicate ecosystem and cost millions to control,” said Kimberly Chevallier, environmental improvement program manager for the Tahoe Regional Planning Agency. “We thank Tahoe’s congressional representatives for this generous support.”

The agreements will support efforts to remove the Eurasian watermilfoil  a pernicious aquatic invasive plant  as well as funding for public outreach and education about aquatic invasive species, and investments in permanent inspection stations. A total of $17 million in Bipartisan Infrastructure Law funds will be available for such work over the next five years.

“Our ongoing collaboration with Tribal leaders and local partners is crucial to successful implementation of President Biden’s Bipartisan Infrastructure Law,” said Service Director Martha Williams.“As stewards of public lands, we’re grateful for ongoing commitments to invest in communities like Lake Tahoe. Today’s investment will further safeguard a region that holds deep cultural and ecological significance.”

The Bipartisan Infrastructure Law makes a $1.4 billion investment in ecosystem restoration and resilience across the country, supporting collaboration with states, Tribes and local communities to restore habitat connectivity for aquatic species, advance habitat restoration and invasive species control, and conserve at-risk and listed species.

Located on Washoe ancestral lands, Lake Tahoe holds significant cultural importance for the Washoe Tribe and is part of the historic range of Lahontan cutthroat trout. To oversee restoration efforts in the Lake Tahoe watershed, the Washoe Environmental Protection Department was established in 1998 and has been a key partner in ongoing restoration work.

A popular area for recreation, the Lake Tahoe Basin faces ongoing threats from the introduction and spread of aquatic invasive species. Common invasive weeds, like the Eurasian watermilfoil, can significantly disrupt aquatic ecosystems and crowd out native species. Aquatic invasive species management is a top priority of the Lake Tahoe Environmental Improvement Program, one of the most comprehensive restoration programs in the nation. For the past 15 years, Environmental Improvement Program partners have worked together to stop the spread of invasive species and prevent new aquatic invasive species from entering Lake Tahoe.

The Service worked closely with the Tahoe Regional Planning Agency and the multi-partner Aquatic Invasive Species Coordinating Committee to identify priority areas for funding under the Bipartisan Infrastructure Law, including permanent watercraft inspection stations to aid in prevention. Under the Environmental Improvement Program, Lake Tahoe watercraft inspectors have inspected more than 100,000 boats since 2008. In that time, no new invasive species have been detected in the Tahoe region. 

To strengthen collaboration with the Washoe Tribe of Nevada and California, the project team also identified several projects that will increase Tribal engagement and participation in ecosystem restoration efforts and inform future program priorities with traditional perspective and methods.
