Aquatic Invasive Species

Boaters who want to launch watercraft at Lake Tahoe, Fallen Leaf Lake, and Echo Lake boat launch facilities will be subject to boat inspections involving the boat hull, engine, live well, bilge and trailer.  Boat inspections will be conducted by the Tahoe Resource Conservation District or marina staffs, who are certified to conduct such inspections.  Boats will be subject to decontamination (washing) if the result of inspection warrants such action.

Paddleboards, kayaks, rafts, canoes, and other hand carried watercraft are subject to screening or inspection  at developed recreation sites. Hand carried watercraft will be subject to inspection and decontamination (washing) if the result of screening or inspection warrants such action. There is currently NO FEE for inspection and decontamination of non-motorized canoes, kayaks and paddleboards.

Details about Inspection and Decontamination Stations and fees for motorized boats can be found here:

Who can you contact if you know your boat needs to be inspected or decontaminated or if you have other questions about Aquatic Invasive Species (AIS) prevention?
Call 1-888-824-6267 (1-888-TAHO-ANS).

Boaters porting to various lakes and shoreline locations from undeveloped parking locations please be aware that you too have an important role in preventing Aquatic Invasive Species from entering Lake Tahoe and the basin's other lakes and streams!!! 


What can boaters and paddlers do to prevent transporting Aquatic Invasive Species?

Trailered boats refer to the Lake Tahoe Boater Card:

Paddlers refer to the Lake Tahoe Paddler Card:

What are Aquatic Invasive Species?

Invasive species infiltrate and cause harm to and can threaten native aquatic ecosystems, recreational boating and swimming, commercial agriculture and local or regional economies. Aquatic invasive species are introduced and spread by moving boating,fishing or other aquatic recreational equipment that have been in contact with contaminated water-bodes to areas that do not have such species.

Thousands of non-native aquatic invasive plants, invertebrates, and disease-causing pathogens are infesting millions of acres of waters across the nation. These invaders cause massive disruptions in aquatic ecosystem function and health and reduce biodiversity in our nation's wetlands, rivers, and lakes. Aquatic invasive species also affect the health and survival of native aquatic fish, amphibians and other macro-fauna.  The financial impact from aquatic invasive species infestations in the United States has been estimated at $138 billion per year in total economic damages and associated control costs.

A strategic Forest Service response to aquatic invasive species is embodied in the National Strategy and Implementation Plan for Invasive Species Management launched in October 2004. The strategy is an aggressive program that harnesses the capabilities of the Forest Service. The Forest Service provides cutting edge leadership in natural resource management and research and development.

A species is considered invasive if it meets these criteria:

  • It is non-native to the ecosystem under consideration
  • It has not been intentionally introduced or is not managed by the state fish and wildlife agencies
  • Its introduction causes or is likely to cause economic or environmental harm or harm to human health


In the Lake Tahoe Basin the following Invasive Species are a concern:
