Lake Tahoe’s best defense against aquatic invaders is prevention, and it takes every boater, paddler, and angler doing their part.
Watersheds & Water Quality > Aquatic Invasive Species
Lake Tahoe is home to one of the nation’s most successful aquatic invasive species (AIS) programs because we’ve made protection a priority. From boat inspections to hands-on weed removal, the EIP is protecting Tahoe’s ecosystem, water quality, and economy from one of the most urgent environmental threats of our time.


The best defense is prevention, and we keep invasive species out of Tahoe through robust inspections, decontaminations, and outreach.

Watercraft spread invasive species into new waterways. Inspections stop invaders before they enter. If your gear touches water, Clean, Drain, and Dry it before your next launch.
TRPA and partners are proud to bring you the Tahoe Boating App to inform boaters about Lake Tahoe, aquatic invasive species, no-wake zone boundaries, area attractions, and how to enjoy the lake safely and responsibly. Lake Tahoe has no-wake zones to keep boaters, paddlers, and swimmers safe.
Lake Tahoe remains one of the clearest lakes on Earth — not by accident, but because of decades of coordinated action. Explore some of our landmark projects in your own backyard.
