Your Actions Matter
Before you enter and after you leave the waters of Lake Mead and Lake Mohave, CLEAN. DRAIN. DRY.
Remove all plants, animals, and mud from your boat, anchor, boots and other equipment before you enter and after you leave the water. If traveling to another body of water, rinse equipment and boat hulls with high-pressure, hot water at one of the park's hot water wash stations (see below).
Before leaving the park, drain all the water from your boat, including the motor, bilge, livewell, ballast, hull and anything else that traps water. Leave drain plugs out during transport.
Dry all compartments and equipment completely before entering another body of water.
IT'S THE LAW - Remove Your Drain PlugLake Mead and Lake Mohave are located in both Arizona and Nevada. Each state has sightly different regulations. You are required to follow each state's rules when on the water. If you launch in Arizona and cross into Nevada, you must follow Nevada regulations, and vice versa.
It is illegal to transport or possess aquatic invasive species in Nevada and Arizona. In both states, you must remove boat drain plugs when you leave the water.
All in and out-of-state motorized watercraft as well as most paddle-craft, such as canoes and kayaks are required to display a Nevada AIS decal. Paddle-craft, such as stand-up paddle boards and float tubes are exempt from the decal requirement. Only Arizona registered vessels are exempt. All vessels registered in Nevada, any other state and non-registered Arizona paddle-craft (canoes, kayaks, etc.) must display the NDOW AIS decal.

Boats moored and slipped at park marinas are required to have their boat inspected and hot washed before leaving the park.
