Overview

Basics

Basics
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.

Threshold Categories

  • Removal of invasive plants will make the nearshore habitat less suitable for reproduction and survival of non-native warm water fish (that exhibit lower reproductive success) when exposed to high levels of UV light), thereby restoring and enhancing native fish species habitat.
  • Removal of aquatic invasive plants in the nearshore will contribute to providing a high quality recreation experience in the nearshore.
  • It has been demonstrated that satellite populations increase the rate of expansion of an invasion and targeting such populations for reduction can act to reduce spread rates, thereby reducing aesthetic and visual impacts in the nearshore.
  • Eurasian watermilfoil has been found to alter phosphorous cycling in the water column in the nearshore of Lake Tahoe, potentially leading to increased algae production. Benefits to water quality will also be realized due to the resultant decline in CDOM (colored dissolved organic material) levels, which would indicate a reduction in the amount of decompositon of organic matter.
