O'Brien Lock and Dam, approximately nine miles away from Lake Michigan. This is the first time a silver carp has been found above the U.S. Army Corps of Engineers' electric dispersal barriers. The silver carp was 28 inches in length and weighed approximately 8 pounds. The fish has been sent to Southern Illinois University for additional analysis.
