Truckee Marsh, 

Help Protect Tahoe

You can make a difference by showing your support of protecting Lake Tahoe by ordering your California Lake Tahoe license plate. Over 95 percent of the fees generated from sales help fund trails, water quality, and restoration projects in the Lake Tahoe Basin.

How to Get Your Plate


The California Tahoe Conservancy plans to restore the complex and unique ecology of the Upper Truckee Marsh. The Conservancy will redirect the Upper Truckee River flows to a historical network of channels through the Marsh. The Marsh once covered 1,600 acres, but 20th century development destroyed much of the wetlands complex.

Restoring the resiliency and ecological functions of the Upper Truckee Marsh

Construction of the Tahoe Keys neighborhood destroyed much of the wetlands in the 1950s and 1960s. The development of the Keys involved considerable dredging and filling of the area, as well as the channelization of the Upper Truckee River as it nears Lake Tahoe.

The Conservancy plans to restore and enhance over 500 acres of floodplain by returning river flows to the center of the Marsh. Returning river flows to the Marsh will improve water quality and enrich native fish and bird habitat. The restored Marsh will act as natural pollution filter, removing fine sediments from the water before it reaches Lake Tahoe. With the Marsh more wet, it will be more resilient to droughts, flooding, and other climate change impacts. The Conservancy will enhance public access and recreation opportunities in the northwest corner of the Marsh. The Conservancy also established a science advisory committee to guide the development of the project’s design and monitoring plans.

After several years of planning and public involvement, the Conservancy Board approved the preferred alternative for the project in December 2015.
Conservancy staff and consultants are completing final steps necessary to start constructing the Marsh project. Initial implementation efforts consist of redirecting high flows into historic channels in the center of the Marsh, converting the “Sailing Lagoon” to functioning wetland, removing fill material, and improving the trail to Cove East Beach. The existing Upper Truckee River channel will continue to carry all of the flow during low water periods. The Conservancy will pursue additional restoration activities after they complete the initial project elements.

Conservancy staff expects to construct the initial stage of the project between 2020 to 2023, pending the Conservancy completing final plans and securing necessary permits.

Funding for the Upper Truckee Marsh Restoration

Conservancy and Department of General Services staff estimates that they can construct the first stage for about $10.6 million. The Conservancy is partnering with several State and federal agencies to secure these funds. The Conservancy is providing $3.2 million from Proposition 68 funds, receiving a $1.7 million Proposition 1 grant from the California Department of Fish and Wildlife, and seeking additional State funding from the Wildlife Conservation Board. Staff is also pursuing funding from the U.S. Army Corps of Engineers through a partnership agreement signed in 2017, and additional federal funding from the U.S. Forest Service.
