Crews have installed an underwater speaker system in the Mississippi River that’s designed to stop Asian carp from spreading.

The new experimental speaker deterrent system was recently installed in the Mississippi River in Genoa, Wisconsin, at Lock and Dam 8; it’s part of an effort to find inexpensive and safe alternatives to stopping the carp from swimming up the river.   

Crews believe the tool will address threats to the St. Croix and Minnesota Rivers as well as the southern pools of the Mississippi River.

On Monday, those involved in the installation will be giving an update on the tool and showing how it works. University of Minnesota professor Dr. Peter Sorensen and members of the U.S. Army Corps of Engineers will be in attendance.

Funding is provided by the Minnesota Environment and Natural Resources Trust Fund as well as private donations.
