SOUTH LAKE TAHOE, Calif. — Work on the project to eradicate invasive plants has resumed at Taylor Creek and Tallac Creek Marsh in South Lake Tahoe.

The Tahoe Regional Planning Agency, in partnership with the USDA Forest Service’s Lake Tahoe Basin Management Unit, began the project in November by clearing vegetation in the marsh in preparation for installing barriers of underwater in marshes adjacent to Baldwin and Kiva beaches this spring, TRPA said when the project began. Lower barriers are mats laid under water to deprive weeds of the sunlight they need to grow.

The barriers help control and eradicate invasive plant species such as Eurasian watermilfoil and will be in place until 2025.



Invasive plants affect wildlife habitat, outcompete native plants, and can impact recreation and water quality.

Swimmers and other recreational enthusiasts should avoid marshy areas where work is taking place and be aware of the underwater hazards posed by slippery bottom barriers and metal rebar stakes.



TRPA said the Taylor and Tallac Creek watersheds have been damaged by historic grazing, recreational infrastructure, construction and erosion. The degraded state has favored the introduction of invasive aquatic weeds into streams and marshes which threaten native species and alter the natural ecosystem of the marshes.

Controlling invasive plants is the first phase of a larger, more comprehensive restoration project for Taylor and Tallac creeks, according to the agency. Aquatic invasive species control and stream restoration are components of the Lake Tahoe Environmental Improvement Program, one of the nation’s most ambitious landscape-scale restoration programs involving more than 80 organizations around the Tahoe Basin.
