What are invasive carp?
Four species of carp brought to the US fifty years ago have spread across one-third of the continent and up the Mississippi River.
A threat to our waters
Invasive carp damage river ecosystems, harm native fish populations, and endanger boaters. They are moving north up the Mississippi River into MN/WI waters.
A proven solution
A decade of scientific research has identified a multi-faceted but simple solution that would solve the carp problem at Pool 5, south of Lake Pepin.
Conserving native fish
Controlling invasive carp does not need to disrupt native fish migration. Doing nothing to control invasive carp will cause far greater damage to native fish species.
2023 Updates
Legislative action: A bill is being drafted asking the MN Legislature to fund implementation of a three-part strategy to stop a reproducing number of invasive carp from passing north of Lock and Dam 5 in the Mississippi River for the foreseeable future and so prevent them from invading state waters above that point. The project would also enhance native fish abundance at this location. For more information, see a summary of frequently asked questions.
Engineering feasibility and cost analysis: In late 2022, Barr Engineering Co. completed its final report, “Engineering Assessment of the Feasibility and Estimated Cost of Installing a State-of-the-Art BAff Carp Deterrent at Mississippi Lock and Dam 5.” A PDF of the report is available in the References & Resources section and can be accessed using this link.
Public awareness: A January 23 article in the Star Tribune by columnist Dennis Anderson provides an overview of what’s been done to date to stop invasive carp in MN and the need for action now. Here’s a link to a simple PDF of the article online, although it’s best read via the Star Tribune’s website (startribune.com).
Action needed
To show your support for controlling invasive carp in Minnesota and the draft legislation mentioned above, please contact your state legislators. Let them know there is no time to wait: A solution for Minnesota’s invasive carp problem must be funded this year.
