Basics
The purpose of the project is to remove aquatic invasive plants (AIP) in Pope Marsh, and exclude plant fragments growing in Lake Tallac from flowing into and infesting the marsh and subsequently, Lake Tahoe. Pope Marsh is identified in the Lake Tahoe Region Aquatic Invasive Species Action Agenda 2021-2030 as a priority project. A survey conducted in July 2023 by Tahoe RCD’s contracted divers detected Eurasian watermilfoil (Myriophyllum spicatum) growing at various densities within a 1.8-acre area. In 2025, survey and hand removal of AIP was conducted by contracted divers and a metal screen was installed on top of the weir separating Pope Marsh from Lake Tallac to prevent further infestation.

Threshold Categories
-
Removal of AIS will contribute to improved fish habitat within Lake Tahoe for native fish and reduce habitat for invasive fish which prey on native fish and disrupt the natural food chain.
-
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.
-
This project will improve water quality by removing aquatic invasive plants, a known contributor to decreased lake clarity.
