With the support of federal, state, regional, and local agencies, the Washoe Tribe of Nevada and California, scientists, and the private sector, the EIP is one of the most successful large-scale conservation programs in the nation.
Our network of more than 80 partners collaborates to solve Lake Tahoe’s most significant environmental challenges. Together, the partnership is implementing projects that not only improve the environment but also enhance recreation opportunities and revitalize communities.
With renewed federal investment and unprecedented collaboration among stakeholders, we are poised to scale our impact—ensuring Lake Tahoe remains a pristine national treasure and a thriving, resilient community.

TRPA was created in 1969 through a bi-state compact between Nevada and California, ratified by Congress. Its mission is to lead the cooperative effort to achieve environmental standards, called Thresholds, that preserve, protect and enhance the unique environment of the basin.
By the 1990s, lake clarity was declining, and it was clear that coordinated, region-wide action was needed. In 1997, at the first Lake Tahoe Summit, TRPA and leaders launched the EIP to accelerate environmental restoration and community revitalization through a shared investment strategy.
Today, TRPA convenes more than 80 “Team Tahoe” EIP partners—including government agencies, nonprofits, the private sector, scientists, and the Washoe Tribe of Nevada and California—to set priorities, fund projects, and track progress for Lake Tahoe’s future.
Federal investment is matched by millions in state, local, and private contributions to accelerate implementation of lake-saving projects.
Team Tahoe has implemented more than 900 projects across the region. Partners work together to prioritize investments, ensuring EIP funding is directed where it delivers the greatest environmental and community benefits. Together, these projects build on one another to produce lasting, on-the-ground results.
The EIP is delivering measurable progress toward Regional Plan goals. With renewed federal investment and unprecedented collaboration among stakeholders, we are poised to scale our impact—ensuring Lake Tahoe remains a pristine national treasure and a thriving, resilient community.
In September 2024, Congress passed the Lake Tahoe Restoration Reauthorization Act with bi-partisan support. The Act extends approximately $300 million in remaining authorization to 2034 and continues federal support for priority EIP projects to protect and restore Lake Tahoe.
The Santini-Burton Modernization Act is the product of a multi-year collaboration by Tahoe’s state and local governments, the bi-state Tahoe Regional Planning Agency, the Washoe Tribe of Nevada and California, non-profits, and the private sector. If enacted, modernization would free up existing funds for ongoing management, allowing the Tahoe Basin to complete more lake-saving Environmental Improvement Program projects to protect Tahoe’s famed clarity, improve recreation access, manage forests, reduce wildfire risk, and expand the presence of the Washoe Tribe of Nevada and California.
