Basics
Aquatic invasive plant removal implemented at Logan Shoals is prioritized in the Action Agenda, a multi-year lake-wide strategy to remove aquatic invasive plants along the shoreline of Lake Tahoe. Methods of removal include barrier installation, diver-assisted suction (if needed), and hand removal. Barriers were installed at this site in 2023 and removed in 2024. Divers continued surveillance monitoring at this site throughout the 2024 plant growing season.

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.
