Michigan takes action

Preventing invasive carp in the Great Lakes is a priority in Michigan. The state is working with regional partners, including state, provincial and federal agencies on prevention and monitoring efforts around the Great Lakes.


In January 2018, Governor Snyder announced the formation of the Great Lakes Basin Partnership to Block Asian Carp. This growing coalition of states and provinces is committed to supporting the $8 million annual cost of operations and maintenance for the Army Corps of Engineers' Tentatively Selected Plan to reduce the risk of invasive carp from entering the Great Lakes at the Brandon Road Lock & Dam in Joliet, Illinois.

Michigan has prepared thorough response exercises to address invasive carp should we find them in the state's waters of the Great Lakes and we have a Mutual Aid Agreement for Aquatic Invasive Species Response, signed by Governor Snyder, with the other states and provinces that will allow them to help us or for us to help them if needed. 

The Michigan DNR has trained with the Illinois DNR in invasive carp population reduction and monitoring exercises in the Illinois River and continues to conduct field exercises and eDNA surveillance in Lake Erie and tributaries of Lake Michigan in partnership with other Great Lakes states and provinces and the federal government.

Michigan is a part of the Asian Carp Regional Coordinating Committee, jointly chaired by the EPA and U.S. Fish and Wildlife Service, which aims to prevent bighead, silver and black carp from entering the Great Lakes and colonizing.


The Great Lakes Invasive Carp Challenge used a global crowdsourcing competition to find 10 innovative solutions to prevent invasive carp from entering the Great Lakes. These new ideas have been shared with leading researchers in invasive carp management across the U.S. 


Michigan is actively monitoring key locations where invasive carp would congregate if they make their way into the Great Lakes, including the St. Joseph and Kalamazoo Rivers. Results of regular environmental DNA (eDNA) monitoring are posted on the U.S. Fish and Wildlife Service Fisheries website.

A management plan for invasive carp outlining the actions to be taken if invasive carp are found in Michigan's waters has been developed. 

Though grass carp pose a less significant threat of harm, Michigan is taking a proactive approach with regulations, enforcement, and using a scientific approach to increase the effectiveness of control efforts.
