Earlier this year, engineers with the U.S. Army Corps of Engineers tested Chicago's electric fish barrier at electrical levels above its normal operating setting. The goal was to understand what happens if the barrier ever needs to operate at higher electrical levels to stop invasive carp from moving toward the Great Lakes, as per a report.
The Electric Dispersal Barrier System sits on the Chicago Sanitary and Ship Canal in Romeoville, Illinois. It creates an underwater electric field designed to deter invasive fish and direct them back downstream, helping block movement between the Mississippi River Basin and the Great Lakes, as per a USACE report.
