Aquatic Invasive Species Program
Prevent, Control, or Eradicate Aquatic Invasive Species
Emerald Bay is one of the most successful aquatic invasive plant (AIP) control treatments completed to date by the Lake Tahoe AIS program. Zero to few aquatic invasive plants had been detected since 2014, until recent surveillance monitoring in 2022 revealed AIP that required a higher level of work that was no longer considered a rapid response action. Dedicated treatment includes diver-assisted suction removal and hand-pulling. To ensure the long-term effectiveness of this work, routine surveillance monitoring will occur, and training of California Department of State Parks divers to conduct annual monitoring and removal of any emerging aquatic invasive plants.
