Prevention Steps

Removing plants from a boat Checkmark Icon

Clean

After boating, before you leave the launch:

Remove all visible plants, animals, fish, and mud from your boat, trailer, or other equipment and dispose of in a suitable trash container or on dry land. Don’t transport any potential hitchhiker, even back to your home. Remove and leave them at the site you visited.

Drain

After boating, before you leave the launch:

Drain water from bilge, live wells, ballast tanks, and any other locations with water before leaving the launch. Invasive viruses, zooplankton, and juvenile zebra mussels and Asian clams can be transported in even just a drop of water!

Dry

Before you arrive at the launch to go boating:

Dry your boat, trailer, and all equipment completely. Drying times vary depending on the weather and the type of material. At least five days drying time is recommended.

Current Zebra & Quagga Mussel Distribution Maps

Nebraska has 5 positive waterbodies forzebra mussels .  Lake Yankton (2017), the Missouri River-the entire length of the river in Nebraska (2016), Lewis and Clark Lake near Yankton, SD (2015), and Offutt Air Force Base Lake in Bellevue, NE (2014). A small infestation was found in Glenn Cunningham Lake in Omaha, NE (2018), the waterbody was drawn down in winter 2018 to freeze and kill the zebra mussel infestation.  Once the waterbody refills it will be sampled frequently for zebra mussel.  Positive waterbodies can be delisted after 5 years of negative sampling for zebra mussels.

Carter Lake (Omaha, NE) is Nebraska's only suspect waterbody, which means only a single water sample has been found to contain zebra mussel larvae and adults have not been found. A single water sample collected in 2017 tested positive and the waterbody can be delisted in 2020 if no zebra mussel laravae or adults are detected. Lake Zorinsky was delisted in 2019 after 3 years of negative sampling for zebra mussels, the eradication effort conducted in 2010/2011 is considered to have been successful.  

Quagga mussels have not been found in Nebraska to date.  To view the current national range map click here.
