In 2014, a county tax bill was passed that provides funds for aquatic invasive species (AIS) prevention. Each year, $10 million will be provided to Minnesota counties to support AIS prevention programs.
County board representatives designate AIS program oversight to a local government within the county. The designated local government works closely with local, state and federal governments, as well as nonprofit and private organizations, to develop and implement AIS prevention programs. Individual counties make decisions on how funds are to be used. Funds must be spent according to state statute, while still abiding by all current laws and regulations.
The DNR's Role:
- Provides technical support to counties, local governments and their partners to develop AIS prevention strategies.
- Receives county AIS plans and resolutions, describing how funds will be used each year.
- Facilitates regional workshops to bring local government staff leading their county's AIS Prevention program together to share and learn from collective experiences, support collaborative efforts, and maintain strong inter-county relationships.
General questions about AIS Prevention Aid and the DNR's role can be directed to the DNR AIS Prevention Planners.
For questions about specific county programs or how counties are using their funds, contact the county directly by referencing the Primary County AIS Contacts list.

AIS prevention aid background
Minnesota Statute 477A.19 - Provides $10 million to counties each year to prevent the introduction and limit the spread of aquatic invasive species. The funds are allocated based on each county's share of watercraft trailer launches (50%) and each county's share of watercraft trailer parking spaces (50%). It is up to individual counties to make decisions on how the funds are to be used while still abiding by all current laws and regulations.
Aquatic Invasive Species Prevention Aid Distributions - Department of Revenue 2014, 2015 and 2016 certification charts showing distribution funds for each county.
- Payments follow traditional aid payment dates: July 20 and December 26.
- The Department of Revenue will develop a certification chart on or before August 1 of each year, for the amount to be paid to each county in the following year.
