OMAHA, Neb. (AP) — The presence of invasive zebra mussels has been confirmed at an Offutt Air Force Base lake south of Omaha.

The Nebraska Game and Parks Commission says a federal wildlife specialist discovered live adult zebra mussels in Offutt Base Lake on May 1, while checking rocks in the shallow water.

The commission has now forbidden any water to be removed from the lake, including by bait buckets and coolers for caught fish.

The species can attach themselves to boat motors, bait buckets and other equipment and make their way from one body of water to another.

Once transferred, they can attach themselves to pipes or other structures, damaging boat motors and reducing the ability to draw water into facilities like water treatment and power plants.
