Tahoe Keepers: Prevent the Spread of Aquatic Invasive Species

All non-motorized watercraft (including inflatables) must be Cleaned, Drained and Dry before launching at Lake Tahoe, moving around the lake, and any surrounding lakes and waterways to prevent the spread of aquatic invasive species (AIS) that will ruin Lake Tahoe. Paddleboards and kayaks with electric motors MUST be inspected at a TahoeBoatInspections.com

ATTENTION:  New Zealand Mudsnails were discovered in Lake Tahoe! Click here to learn how to prevent their spread.

Paddlers are required to self-inspect their watercraft and gear and ensure it is 100% clean, drained, and DRY.  Inflatable paddle gear is arriving with water collected in folds and storage bags, and paddles full of water.  If you find contaminants on your paddle craft or gearOR you recently visited infected waters, you MUST go to an inspection station for a free decontamination. Learn more at TahoeBoatInspections.com.

Asian clams, Eurasian watermilfoil and New Zealand Mudsnails have changed Tahoe’s ecosystem and threaten Lake Tahoe’s famous water clarity.  Luckily, these AIS are not yet established in Fallen Leaf Lake, Echo Lake, and Spooner Lake.  Let’s keep it that way.

Invaders like Zebra and Quagga Mussels spread through the transport of water and debris that can collect in cockpits and hatches, and cling to outer hulls, rudders, paddles, SUP leashes, and life jackets/belts. Spreading AIS violates local, state, and federal laws.

Asian Clams are an Aquatic Invasive Species (AIS), which are invading Lake Tahoe.

Learn how to stop the transfer of AIS to Tahoe and Truckee water bodies by self-inspecting and decontaminating your paddle craft and gear after each use.   It’s easy and it matters.

Tahoe Keepers logoThe Tahoe Keepers online training program demonstrates how to Clean, Drain and Dry your watercraft and gear every time you haul out or move between water bodies, and properly Dispose of any plants or debris. Paddlers who successfully complete the free program will become members of the Tahoe Keepers stewardship community, and will receive “Proof of Training” credentials and a cool sticker!

The Tahoe Keeper sticker signifies that you know how to self-inspect your gear. However, if you paddle on the Nevada side of Lake Tahoe, you are required to purchase and display a Nevada AIS decal. Visit www.ndow.org for details.

Clean paddle craft and gear with pressurized water, removing all dirt, plants, and other material from your rudder, hull, cockpit, life jacket, SUP leashes, and paddles. DISPOSE of foreign matter in a trash can or above the waterline on dry land. Or carry it out.


Drain the water from your boards, paddles, hatches, cockpits, and gear on land before you leave the immediate area.

3) DRY

Dry your paddle craft and gear before and after launching. Inflatable gear can carry infected water in the folds. Use a towel and air dry in the sun.

Free kayak, canoe, paddle board, and non-motorized watercraft inspections and decontaminations are available at each roadside boat inspection station located at Truckee, Alpine Meadows, Spooner Summit, and Meyers. Directions to these roadside stations, a list of water bodies containing aquatic invasive species, and answers to frequently asked questions, are also available at tahoeboatinspections.com.

If you plan on paddling in Nevada, you are required to purchase a NV AIS Decal.  Becoming a Tahoe Keeper does not exempt you from purchasing a NV AIS decal that supports the state’s AIS boating education program. California doesn’t have an AIS fee requirement at this time.
