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