Aquatic Invasive Species


Aquatic Invasive Species Picture22



Welcome!  The Douglas County Water Resources and AIS Program (“AIS Program” for short) serves Douglas County residents, seasonal visitors, and businesses by working to keep our lakes and rivers healthy.  Maintaining clean and healthy waters in Douglas County is important because our waterways provide opportunities for recreation, fishing, tourism, and business, and support the wildlife and beautiful Northwoods lake ecosystems this area is famous for.  Aquatic invasive species, or “AIS” pose a serious threat to our lakes and rivers, and preventing their spread is a major focus of the AIS Program.  The Douglas County AIS Strategic Plan details the risks of AIS and our strategy for AIS prevention and management.  Please enjoy exploring the updated AIS Program website to learn about the many AIS prevention, monitoring, and control projects we’re implementing with partners from around the region and how you can get involved.


Community members from Lake Associations, Villages, Townships, Sanitary Districts, and stakeholder clubs have repeatedly expressed a need for a county-wide approach to AIS Prevention.  The County AIS Program works to serve this need.


So far, the AIS Program has brought $263,223.72 into Douglas County for the important work needed to protect our local resources and safeguard our clean waters for the future.  Many of our projects are funded by competitive grants and supported by local partnerships.
















 Sincere appreciation goes out to our valued partners on current and past AIS projects:
