Invasive Species

Aquatic invasive species are a growing threat to waterways throughout the nation and the west. These aquatic invaders include over 16 plant and animal species such as Eurasian watermilfoil, curlyleaf pondweed, zebra and quagga mussels, and Asian clams. Consequences of establishment include degradation of water quality, loss of important habitat for native species, impacts to water conveyance systems, boats, piers and other structures, and negative economic impacts to the Lake Tahoe Region.

Aquatic invasive species are known to be transported from infested lakes and rivers via a variety of pathways, including trailered boats, fishing gear, waders, construction machinery, kayaks, and other watercraft.  They pose a serious threat to the Tahoe Basin’s unique natural environment and economy.

What you can do to protect Lake Tahoe from aquatic invasive species:

  • If you are a boater coming to Lake Tahoe you must get your boat inspected at one of the five inspection stations in and around Lake Tahoe. Be sure and arrive clean, drained and dry. Visit for more information.
  • If you have a non-motorized watercraft, such as a kayak, canoe or standup paddleboard, consider becoming a Tahoe Keeper and learn how to self-inspect your watercraft to help protect your favorite place and your favorite pastime from the threat of aquatic invasive species.
  • Anglers, learn how to thoroughly clean and dry your waders and fishing gear to prevent the spread of New Zealand mudsnails and other tiny aquatic hitchhikers. Helpful instructions on cleaning and decontamination methods can be found at Nevada Department of Wildlife (NDOW) and California Department of Fish and Wildlife (CDFW) web sites.
  • Become an Eyes on the Lake volunteer and learn how to identify and report aquatic invasive species.
