The Conservancy manages programs to help protect Lake Tahoe's water quality and conserve wildlife habitat, watershed areas, and public access on the California side of the Lake Tahoe Basin. The Conservancy is a primary implementer of the State of California's responsibilities under the Environmental Improvement Program (EIP) for the Lake Tahoe Basin - a 1997 agreement between California, Nevada, the Tahoe Regional Planning Agency, the federal government, local governments, and various private entities. The EIP is updated periodically to include more refined estimates of projects, modifications in the scope of identified projects, and inclusion of new projects. The 2008-2018 EIP was finalized in July 2009. However, based on the 2008-2018 EIP, the Conservancy has identified its own EIP project list for new funding.
