The Project will repair the largest remaining wetland in the Sierra Nevada. The project includes over 250 acres of wetland enhancement, 11 acres of wetland creation, aquatic invasive species abatement, and public access improvements. The Project will restore the geomorphic processes and ecological functions in the Upper Truckee Marsh (Marsh) by routing a portion of the Upper Truckee River (UTR) back into the historical channel alignment, reclaiming wetland areas affected by past development actions, and by providing the public with appropriate access to the Marsh and Lake Tahoe.
California Tahoe Conservancy
Objectives of this Project are to:
• Re-activate over 13,500 feet of relict stream channels via construction of over 1,400 feet of pilot channels and create 11 acres of wetland by filling a portion of a marina (2.7 acres) and removal of fill placed during development (8.3 acres).
• Redistribute sediment laden UTR flows over 250 acres of the Marsh during large flow events. The anticipated outcome of this objective is a decrease of fine sediment and nutrient loads entering Lake Tahoe from the UTR.
• Raise local groundwater table and rewet over 250 acres of wetland in the Marsh to enhance native wetland vegetation, emergent lagoon vegetation, and willow density and distribution.
• Restore natural geomorphic, hydrologic, and vegetative conditions over 250 acres of wetland in the Marsh to enhance aquatic and terrestrial habitat, including songbirds, bats, waterfowl, amphibian, native fish, and raptors.
• Improve the biological community condition of aquatic and terrestrial species, including songbirds, bats, waterfowl, amphibians, native fish, and raptors.
