Meadows area, and the endangered shorezone plant Lake Tahoe yellowcress (Rorippa subumbellata) is found near the mouth of the river on the shores of Lake Tahoe. Much of the vast Truckee Marsh was filled to create the Tahoe Keys subdivision. Further hydrologic modification occurred (reaches of the river were channelized) for construction of the South Lake Tahoe airport. Spills of treated wastewater from the South Tahoe Public Utility District's export facilities in this watershed are an ongoing concern. The straight boulder-lined man-made channel by the airport was converted back to a more natural, meandering course as of November, 2011. California State Parks acquired two properties to protect wet meadows and floodplain habitat along the Upper Truckee River in the mid 1980s: Washoe Meadows State Park (WMSP) and Lake Valley State Recreation Area (LVSRA).
