Upper Truckee Marsh Restoration Project

In the fall of 2016, the California Tahoe Conservancy selected Northwest Hydraulics (nhc) as the lead designers of this comprehensive and extremely important restoration project. WBS, along with Balance Hydrologics, was selected as a critical team member to assist with development of associated documents and a 50% level of design including  specifications and details, emphasizing biotechnical (vegetative) methodologies.  WBS was part of the original team (Global Environmental) and in 1995 and 1996 identified and mapped the plant communities in the project area and has extensive knowledge of this ecosystem and appropriate restoration methodologies.

As per the CTC web site. 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”.

WBS joined team members in 2016 for a late season but essential site survey to evaluate conditions and the preferred alternative, evaluating information gaps, methods, and details. WBS continues with site surveys and design of this large and critical restoration project during high lake levels and challenging conditions. The project includes construction of new pilots channels, floodplain, oxbows, and filling of the old, sediment generating channel and will be phased over several construction seasons.
