Aquatic Invasive Species (AIS)   

Aquatic invasive species(AIS) include fish, invertebrate, and plant species that have been introduced into a  new aquatic environment,  having been spread to locations where they do not naturally occur.  Once introduced, AIS populations can grow quickly because of the lack of natural predators in their new environment.  AIS can cause economic or environmental harm or harm to human health. And, they negatively impact the quality of outdoor recreation experiences. 


Each of us can PREVENT THE SPREAD of these invasive species in the
lakes & streams of Yellow Medicine County & greater Minnesota!

For additional prevention: spray watercraft & trailer with high pressure water, rinse with very hot water, dry for at least 5 days.

CLEANInspect your watercraft, trailer & gear.  Remove all plant material, mud & foreign objects. 

DRAIN Remove all water from the watercraft, including the motor, bilge, livewells & bait buckets.

DRY.  Open all compartments & allow the watercraft & trailer to dry for at least 5 days before entering another body of water.

In 2023, Yellow Medicine, along with a dozen other MN Counties, helped support these catchy AIS prevention videos presented by the MN Lakes and Rivers Advocates to remind people to HELP STOP THE SPREAD of aquatic invasive species.  Feel free to dance along.

  • 2016-2024 Prairie Sportsman AIS message, sponsorship.  Current sponsors include Wright, Meeker, Big Stone, Lac qui Parle and Yellow Medicine Counties. The show is now being aired on PBS stations in EIGHT states, spreading the AIS prevention message to a broad audience.

*LICENSE HOLDERS - OVER 10,000 license sleeves with an AIS prevention message have been provided to area businesses where fishing  & hunting licenses are sold.


*DRINK COASTERS -  2,750 drink coasters carrying AIS prevention and species ID INFO distributed to local businesses.

*ICE FISHING PROMOs - In 2018  & '19,  1,000 terry fishing towels carrying the “Clean Drain Dry “ message & nearly 300 stocking hats and fish rulers bearing the AIS prevention message were made available to local fisherman by Yellow Medicine and Lac qui Parle staff at area ice fishing tournaments.  Fisherman were also invited to win a bait cooler (or a fishing pole for younger participants) in exchange for their commitment to do their part to prevent the spread of aquatic invasives.

 *Monitoring of local waters established traffic                  patterns of an average of 10 watercrafts per day at Wood Lake and Del Clark Lake and 1 per day at the remaining accesses. The equipment purchased to monitor traffic was transferred to Yellow Medicine County Parks Department. One was lost under the surface of Curtis Lake. Memorial, Independence, and Labor Day Weekends saw over one hundred crafts per day entering and leaving the water. This pattern held true for multiple years, and monitoring was abandoned.

*Hundreds of hours of rapid training and networking was invested by various SWCD staff and board members since 2014.


*With the exception of a one time spotting of Zebra Mussel on the Chippewa County side of the Granite Falls dam, Yellow Medicine County remains free of aquatic invasive species.


*Investment and Involvement in community events throughout the county.
