Aquatic Invasive Species (AIS) Program
The association regularly attends meetings with the Minnesota DNR and the Watershed District to learn about upcoming and ongoing projects to protect the lake. Currently Lake Riley is monitoring zebra mussel activity, Eurasian watermilfoil, and Curly-leaf Pondweed.
Clean In and Out
When boating or fishing in Minnesota, protect your Lake Riley by following state aquatic invasive species laws:
1. CLEAN all visible aquatic plants, zebra mussels, and other prohibited invasive species from watercraft, trailers, and water-related equipment before leaving any water access or shoreland.
2. DRAIN water-related equipment (boat, ballast tanks, portable bait containers, motor) and drain bilge, livewell and baitwell by removing drain plugs before leaving a water access or shoreline property. Keep drain plugs out and water-draining devices open while transporting watercraft.

3. DISPOSE of unwanted bait, including minnows, leeches, and worms, in the trash. It is illegal to release bait into a waterbody or release aquatic animals from one waterbody to another. If you want to keep your bait, you must refill the bait container with bottled or tap water.

Report an Infestation
If you suspect a new infestation of an aquatic invasive plant or animal, note the exact location, take a photo or keep the specimen, and call the AIS specialist in your region.
AIS Contacts List
Eurasian watermilfoil typically has 12 to 21 pairs of leaflets. The native northern watermilfoil, with which it is often confused, usually has 5 to 9 pairs.
Likely means of spread: Milfoil may become entangled in boat propellers, or may attach to keels and rudders of sailboat. Stems can become lodged among any watercraft apparatus or sports equipment that moves through the water, especially boat trailers. Learn More
