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

In October 2022 during a surveillance monitoring survey, a dense Eurasian watermilfoil infestation was observed by divers. In 2023, Tahoe RCD's contracted dive team installed barriers in June to control Eurasian watermilfoil. Barriers were removed in November 2023, and follow-up surveys and plant removal continued in 2024. Due to successful diver removal efforts and minimal detection of newly rooted Eurasian watermilfoil during surveillance visits in 2024, this project has reached post-implementation surveillance status. All future surveillance visits will be documented in Project # 01.03.01.0037 Lake-wide Surveillance and Site Assessments.
