Chisago County Aquatic Invasive Species Prevention     

The goals of the Chisago County Aquatic Invasive Species (AIS) Program are to prevent the spread of AIS through conducting watercraft inspections, decontamination of watercraft, providing education and outreach to citizens, enforcing AIS laws and regional coordination. The County conducts Early Detection activities through zebra mussel veliger sampling, installing zebra mussel monitoring plates, and conducting aquatic plant Point-Intercept surveys. Chisago County will implement Rapid Response actions if zebra mussels or other AIS are found in a lake or river located in the County.

Chisago Lakes Lake Improvement District

One of the goals of the Chisago Lakes Lake Improvement District is to promote the reduction of non-native Aquatic Invasive Species (AIS). Aquatic Invasive Species are non-native plants, animals and other organisms. When they are introduced into a lake or river, they cause harm to the ecosystem. Once in a lake or river they can be impossible to eliminate and difficult to manage. Each year, thousands of watercraft users come to local lakes and rivers, potentially bringing zebra mussels and other AIS along with them.
