Aquatic Invasive Species (AIS) Control Grants help prevent and control the spread of aquatic invasive species in the waters of the state. These grants can be used for education, prevention, planning, early detection, rapid response and established infestation control projects.

Who can apply

Counties, cities, towns, villages, tribes, public inland lake protection and rehabilitation districts, and town sanitary districts and other local governmental units as defined in s. 66.0131(1)(a), Wis. Stats., [exit DNR] qualified lake associations as defined in s. 281.68(1)(b), Wis. Stats., [exit DNR] qualified school districts, private and public colleges, universities and technical schools, qualified nonprofit organizations, river management organizations, state and federal natural resource or land management agencies and FERC-licensed hydroelectric corporations are eligible to apply for funding for an aquatic invasive species prevention and control grant for any waters of the state including lakes, rivers, streams, wetlands and the Great Lakes.

River management organizations and lake associations must be a qualified organization to be an eligible project sponsor. Qualified nonprofit organizations whose purpose includes the prevention and control of aquatic invasive species are eligible project sponsors. Check with your appropriate DNR Regional Environmental Grant Specialist [PDF] to see if your group is currently eligible to apply, or review the qualification requirements [PDF].


Education, prevention and planning projects

The maximum award shall be $150,000. Applications shall be separated into 2 classes - those requesting less than $50,000 in state share and those requesting $50,000 or more in state share. Each class of projects shall be evaluated separately and have equal priority for funding. For watercraft inspection program projects, state share is limited to $4,000 annually for each public boat launch facility not to exceed 75 percent of the total project cost up to the maximum grant amount.

Established Population Control Projects

The maximum grant award is capped at $200,000 though smaller projects are encouraged. These grants target the eradication or substantial reduction and long term control of aquatic invasive species (AIS) with the goal to restore native species communities. Eligible projects include department approved control activities recommended in a management plan or purple Loosestrife bio-control projects (no plan approval required).

Research and demonstration projects

The total available annual funding is limited to $500,000 for this category.

Maintenance and containment projects

The maximum award will be determined by the department and based on the project's applicable application fees and specified monitoring and reporting requirements in the permit or department approved plan. Award will not exceed reimbursement of permit fees.

Order of priority for funding projects

  1. Control pioneer populations of aquatic invasive species.
  2. Prevent the spread of aquatic invasive species to unpopulated waters.
  3. Control established infestations of aquatic invasive species and restore native aquatic species communities.
  4. Provide research and demonstration that advances the states knowledge and understanding of aquatic invasive species control.
  5. Ongoing maintenance to contain aquatic invasive populations within a waterbody.


Annual Application deadlines:

  • AIS Education - December 10
  • AIS Established Population Control - February 1
  • AIS Early Detection - Continuously accepted


Water Quality Lab Work

State Lab of Hygiene (SLOH) costs: If your project includes the collection of water chemistry samples and analysis at the State Lab of Hygiene, you must complete a projected SLOH costs spreadsheet and submit it with your application. This form is not included in the application packet. Contact your DNR Lake Coordinator for help in filling out this form.

Laboratory Test Request Form: The laboratory test request form is an important link between the laboratory and field personnel. The laboratory relies on the test request form to obtain the information necessary to prepare and analyze the sample properly. For more information on completing the laboratory test request form contact your DNR Lake Coordinator
