Earlier this year, the U.S. Army Corps tested Chicago's invasive-carp barrier at 3 electrical levels. Now, engineers know how the system behaves when voltage rises to 4.6 volts per inch, helping prepare for a future Great Lakes invasion threat

Engineers tested Chicago's electric fish barrier at higher electrical levels this year. This testing aimed to understand potential responses to invasive carp threats. Data was collected in both winter and summer conditions for comprehensive analysis. The study also assessed safety implications of increased electrical currents around the barrier.
