• All motorized vessels, including electric vessels and trailered non-motorized vessels, require an inspection.
• New boats and engines are tested in water before leaving the factory and are still required to be inspected.
• All hand-launched non-motorized vessels, like canoes, kayaks, and paddleboards, are subject to inspection and/or decontamination. All inspections and decontaminations are provided free of charge for non-motorized vessels. Visit Tahoe Keepers to learn how to inspect and Clean, Drain, & Dry your vessel.

• An optional appointment system has been created for your convenience and to improve operational efficiency at inspection stations. During the summer boating season, it is accessible on the Locations and Hours page.
• Appointments are an additional $15.
• Inspections will also be available on a first-come first-served basis at all inspection locations.

Be sure to have your keys, as well as anything that comes in contact with water, such as ballast bags, anchors, sea strainers, life jackets, and additional gear.

• There is a fee for motorized watercraft inspections based on the length of the vessel.
• There is a fee for decontamination based on vessel complexity and adherence to Clean, Drain, Dry protocol.
• There is no fee for inspection of electric motors or non-motorized vessels. Decontamination fees apply for trailered watercraft. Decontaminations are free for hand-launched watercraft.
• Please see our Stickers and Fees page for the most up to date fees.

Invasive species, like quagga, zebra, and golden mussels, pose a threat to Lake Tahoe and can be transported overland via watercraft. Learn more about invasive species here.

• Clean up any oil, dirt, and debris inside bilges and storage compartments, and remove all items inside these compartments prior to arriving for your inspection.
• Drain water from your drive unit, sea strainers, bilge, ballast tanks, live wells, and any storage compartments.
• Dry the entire vessel, including toys and gear, for as long as you can in between launches.

Make sure all systems are operational, including batteries, engine(s), pumps, etc. If you have any special adapters or a flush kit for your engine, please bring them with you to the inspection station.

For vessels with ballasts, make sure to bring all ballast bags with you to the inspection station.

All watercraft will be decontaminated (separate fee will apply). Arrive Clean, Drained, and Dry to avoid additional decontamination fees.

Effective 2025, all motorized and trailered watercraft without a valid Tahoe seal will receive decontamination to protect Lake Tahoe from golden mussels.

Decontaminations are available at our roadside inspection stations during the summer. Contact us to schedule a decontamination during the winter.

Decontamination is a process where affected systems on a vessel are flushed using only hot water to kill any possible invasive species.

Typical decontaminations last from 10-30 minutes, depending on the complexity of your vessel. Please bring any special flush adapters with you to ensure a speedy process.

The minimum cost of decontamination is $30, and increases based on vessel complexity and adherence to Clean, Drain, Dry protocols. Arrive Clean, Drained, and Dry to prevent additional decontamination fees. Please see our Stickers and Fees page for the most up to date information.

Please contact us to request a decontamination for another body of water. Visit dbw.parks.ca.gov/inspections for contact information for other bodies of water.

• All motorized vessels require a seal and sticker to launch in Lake Tahoe and surrounding regional waterbodies.
• Tahoe In & Out stickers are eligible for unlimited inspections during the calendar year. Additional decontamination fees apply.
• A Single Inspection Pass is good for 1 inspection and valid for 7 consecutive days of sealing and unsealing at Tahoe launch facilities.
• Tahoe Only stickers are reserved for vessels with an intact Tahoe inspection seal.

If you launch somewhere else, you need to remove the seal and get inspected and decontaminated before launching in the Lake Tahoe region again.

No. All trailered, motorized watercraft must have a Tahoe sticker and seal to launch in Tahoe.

• The only seals accepted at Lake Tahoe are Tahoe, Fallen Leaf and Echo seals.
• The only seals accepted at Fallen Leaf and Echo Lakes are seals for those respective lakes.

• If you already have a seal, you do not need an inspection. Tahoe Only stickers can be purchased at an inspection station or launch facility on Lake Tahoe, except for Fallen Leaf or Echo Lakes.
• If you would like to purchase a Tahoe In & Out annual pass, please visit one of the roadside inspection stations.

Yes. All motorized vessels require an inspection and decontamination.

eFoils, eSUPs, electric wakesurf boards, and trolling motors on small kayaks are examples of hand-launched electric watercraft (HLEW).

Hand-launched electric watercraft (HLEW) must be inspected prior to the first launch each calendar year to receive their free electric sticker.

Inspections and decontaminations for HLEW are free, and HLEW are expedited to the front of the line at inspection stations.

Although hand-launched electric watercraft (HLEW) may be launched outside of designated launch facilities, including without a seal, HLEW users must possess an annual electric Tahoe AIS Program sticker.

Hand-launched motorized vessels can have small pipes, internal cavities, propellers, and more that can harbor invasive species. Even one drop of water can contain aquatic invasive species.

Violators of TRPA Code of Ordinances 63.4 are subject to a minimum $5,000 monetary penalty.

The signed proof of inspection for hand-launched electric watercraft (HLEW) outlines program requirements. HLEW users attest to:

• Clean, Drain, and Dry their watercraft before and after every launch.
• Reinspect at a Tahoe station after launching in waters outside of the Tahoe Region.
• Reinspect at a Tahoe station before launching at Fallen Leaf and Echo Lakes.
• Reinspect at a Tahoe station for free electric sticker every calendar year.

While you can launch your HLEW with a current electric sticker, we encourage you to reinspect at the station for a new proof of inspection.

• Large or oversized commercially transported boats will need an AIS inspection and decontamination prior to arriving at any launching facility in the Lake Tahoe Basin. The boat operator will need to call the Hotline, 888-824-6267, at least 72 hours in advance of arrival, Monday through Friday, to help coordinate the inspection.
• If coming from outside of Nevada or California, boat transporters can call 844-311-4873 prior to hauling to have a destination state representative reach out to facilitate and expedite the watercraft inspection process anywhere in the Western U.S. More information can be found here.

Note: Trailered non-motorized vessels (like sailboats) are required to be inspected and decontaminated. Decontamination fees apply.
