The discovery of the invasive golden mussel in the Bay-Delta near Stockton has raised concerns among environmental agencies. Dennis Zabaglo, aquatic invasive species program manager at the Tahoe Regional Planning Agency (TRPA), stated, “While this discovery is concerning because of the proximity to Lake Tahoe, our watercraft inspection program is robust and we will continue our existing protocols to prevent its spread to the Lake Tahoe Region.”
The TRPA and the Tahoe Resource Conservation District lead Lake Tahoe’s Aquatic Invasive Species Program, collaborating with over 40 public and private partner agencies. The program was established in 2008 with a mission to prevent, detect, and control aquatic invasive species in order to protect Lake Tahoe’s ecosystem.
Under the Lake Tahoe Watercraft Inspection Program, all motorized watercraft are inspected and decontaminated if necessary before launching. Non-motorized paddle craft can also receive free inspections at regional stations. Since 2008, staff have inspected 113,000 boats for aquatic invasive species due to their potential environmental and economic impacts.
Zabaglo emphasized the importance of these measures: “This news underscores the importance of the program. Now more than ever non-motorized paddlers, kayakers, and even beach goers must learn how to Clean, Drain, and Dry their gear through the free Tahoe Keepers program before launching anywhere in the region.”
The golden mussel originates from rivers and creeks in China and Southeast Asia and was likely introduced via international shipping. This species poses similar ecological threats as quagga and zebra mussels, which have not been detected in Lake Tahoe.
In response to this finding, the California Department of Water Resources is preparing a rapid response plan that includes additional monitoring efforts to assess population extent and manage potential vectors.
