Aquatic Invasive Species Program
Prevent, Control, or Eradicate Aquatic Invasive Species
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.
