Cold Creek/ High Meadow Ecosystem Restoration
Client: USFS- Lake Tahoe Basin Management Unit
Waterways, in coordination with the USFS Lake Tahoe Basin Management Unit (LTBMU) and Swanson Hydrology, has developed designs to restore the mainstem and tributaries of Cold Creek in the High Meadow Complex (HMC) near South Lake Tahoe, California. The basic restoration objective is to increase soil moisture within approximately 70 acres of meadow area by modifying the morphology and hydrology of the streams in a manner consistent with natural geomorphic processes. Work involves re-constructing approximately 8,700 linear feet of channel and raising the elevation of the streambeds by 2 to 4 feet. The project will significantly increase the diversity and density of meadow wetland vegetation species and shift some areas from seasonally dry and sparse mesic meadows to wet meadow conditions.
The project’s three-year construction plan was completed in 2012, with Waterways providing on-site construction observation.
