Basics
This project area is located immediately downstream from the dam located in Tahoe City. In 2019, it was determined that the infestation extended for ~3 miles and it was estimated that 15-20% of this area is infested with Eurasian watermilfoil. Techniques for removal are determined by water level, flow rates, and recreational use, and include bottom barriers, diver-assisted suction removal, and hand pulling. Because of the large extent of this infestation and lack of a more recent survey of the infestation, renewed planning to engage appropriate partners, and an effort to solicit funding is needed.

Threshold Categories
-
Removal of AIS will contribute to improved fish habitat within Lake Tahoe for native fish and reduce habitat for invasive fish which prey on native fish and disrupt the natural food chain.
-
This project will enhance the recreational experience on the Truckee River, a known area for rafting, by removing invasive weeds that impact the scenic beauty of the river and allowing for more open area for rafts and swimming.
-
This project will improve water quality by removing aquatic invasive plants, a known contributor to decreased lake clarity.
