August 8, 2017 — The U.S. Army Corps of Engineers has proposed spending $275 million to upgrade defenses against an invading force. The enemy? A fish. Specifically, Asian carp that are threatening to break through to the Great Lakes.
In June, a live Asian silver carp was caught in the Illinois Waterway just 9 miles from Lake Michigan. Scientists fear that if the voracious carp establish themselves in the Great Lakes, they could devastate the region’s $7 billion fishing industry.
The Corps of Engineers wants to upgrade the Brandon Road Lock and Dam near Joliet, Ill., on the Des Plaines River. The waterway is a link between Lake Michigan and the Mississippi River, where Asian carp are already a big problem. The Associated Press writes, “The Brandon Road complex is considered a bottleneck where defenses could be strengthened against fish swimming upstream toward openings to the lake at Chicago.”
