Upper Truckee Marsh

The Upper Truckee Marsh’s flat expanse serves as a last defense and natural filter, cleansing water before it enters Lake Tahoe.

Restoration Opportunities

In the last 150 years development has eliminated more than half of the original 1300 acre Marsh.  The Conservancy has acquired 600 acres to restore the river’s natural cleansing function and subsequently increase habitat quality for plant, wildlife, and fish species.


In order to achieve the Conservancy’s objectives, four restoration alternatives and a “no action” alternative have been developed in a Draft Environmental Impact Report/Environmental Impact Statement/Environmental Impact Statement (Draft EIR/EIS/EIS). The restoration alternatives utilize technical analysis, agency review and community input to reconnect the river with the Marsh.

Five public meetings and hearings were held to provide interested persons with the opportunity to learn about the project and submit comments on the Draft EIR/EIS/EIS prior to April 8, 2013. Staff presented a preliminary staff recommended alternative to the Board for informational purposes on September 18, 2014 that includes:

  • Restoration Element of Alternative 3, Middle Marsh Corridor: Reconnect the Upper Truckee River to the center of the UTM, allowing flows to spread over the vast expanse through a naturally functioning, deltaic channel network.
  • Recreation Element of Alternative 5, Eastside of the UTM : Retaining the existing trail and neighborhood access points along the eastern perimeter of the UTM, providing access to the shoreline of Lake Tahoe, and continuing the dispersed recreation experience.
  • Recreation Element of Alternative 3, Westside of the UTM: Enhancing the trail to Lake Tahoe by improving ADA accessibility, creating viewpoints of interest, and providing educational and resource interpretation opportunities, while maintaining the existing developed recreation experience.

Next Steps

Staff will present an update to the Board on September 17, 2015 and anticipates Board approval of the project and certification of the Final EIR at the December 10, 2015 Board Meeting.

Pending required approvals and available funding, the multi-year project could proceed to construction as early as 2018.
