During the 2014 legislative session, a county aid program was created to help prevent the spread of aquatic invasive species (AIS). Based on the number of trailered watercraft launches and trailer parking spaces, Washington County received $139,581 in 2015, $139,013 in 2016, and $132,169 in 2017. Since the program began, the county has awarded grants to lake associations, watershed districts, and others through an open and competitive request for proposals (RFP) process.
The Minnesota Department of Revenue has certified $135,887 for AIS prevention aid for Washington County in 2019. The county plans to run a competitive request for proposal process to award $77,887 of these funds to entities focusing on prevention projects. The Washington County Conservation District has been awarded $74,000 to implement a county-wide AIS program, and to implement objectives from the Washington County Aquatic Invasive Species Prevention, Early Detection and Rapid Response Plan.
