NDGF zebra mussels
The North Dakota Game and Fish Department has confirmed invasive zebra mussels in Horseshoe Lake, Richland County, after detecting zebra mussel veligers in routine plankton tow net samples.
Department aquatic nuisance species coordinator Ben Holen said subsequent follow-up sampling found additional adult mussels in the lake.
The 275-acre lake is located 5 miles southwest of Hankinson and is near Lake Elsie, which has had zebra mussels present for a number of years.
Horseshoe Lake is now considered a Class I ANS Infested waters. Emergency rules will go into effect immediately to prohibit the movement of water away from the lake, including water for transferring bait. Notices will be posted at lake access sites.
Zebra mussels are just one of the nonnative aquatic species that threaten our waters and native wildlife. After using any body of water, people must remember to follow North Dakota regulations:
- Remove aquatic vegetation before leaving the water access and do not import into North Dakota.
- Drain all water before leaving the water access.
- Remove drain plugs and devices that hold back water and leave open and out during transport.
- Do not import aquatic bait into the state. For Class I ANS Infested waters, aquatic bait cannot be transported away from the water during the open-water months. In all other areas, bait must be transported in a container that holds 5 gallons or less. It is illegal to dump unused bait on shore or into the lake.
- All docks, lifts and related equipment must be dried and left out of water for at least 21 days before being placed in another water.
In addition to North Dakota regulations, the Game and Fish Department strongly recommends the following:
- Avoid mooring watercraft in zebra mussels infested waters.
- Clean – remove plants, animals and excessive mud prior to leaving a water access.
- Drain – drain all water prior to leaving a water access.
- Dry – allow equipment to dry completely before using again or disinfect.
