(November 21, 2018 – Ann Arbor, MI) — Yesterday, the U.S. Army Corps of Engineers released its final draft plan to keep Asian carp out of the Great Lakes. The draft chief’s report of the Brandon Road Lock and Dam includes both structural and nonstructural measures including an engineered lock fitted with an electric barrier, a bubble barrier, an acoustic barrier, and a flushing lock to stop aquatic invasive species like Asian carp, while maintaining navigation for shipping. The Brandon Road Lock and Dam is located just south of Chicago and is a critical chokepoint to help stop Asian carp from continuing to swim closer to Lake Michigan. The estimated cost of the project is $777.8 million, up from an earlier estimate of $275 million. A previous draft of the plan included water jets in place of the bubble barrier.

Federal Register notice:
Asian carp include species of bighead, silver, black, and grass carp. After escaping from southern United States aquaculture facilities, they have spread rapidly and have reduced native fish populations in waters connected to the Mississippi River watershed, which connects to the Great Lakes watershed through the Chicago Area Waterway System. Asian carp pose a significant threat to our economy, outdoor heritage, and way of life. In addition, the invasive species is a clear and present danger to the Great Lakes sport-fishery, which is estimated to generate at least $7 billion each year in economic activity.
Marc Smith, director of conservation partnerships for the National Wildlife Federation Great Lakes Regional Center, issued the following statement in response to the release of the updated plan:
“Across the country, Asian carp are undermining our nation’s fisheries and threaten the Great Lakes $7 billion annual sport-fishery. The Army Corps of Engineers plan to rebuild the Brandon Road Lock and Dam south of Chicago is our opportunity to put stronger measures in place to keep Asian carp out of the Great Lakes. The plan includes a gauntlet of technologies to prevent Asian carp from moving past the lock, while maintaining navigation for shipping. The investment in this project pales in comparison to the economic risk if Asian carp invade the Great Lakes. We intend to review the updates to the plan in detail and offer official public comment later, but at first glance this looks like the plan we need to protect our waters, our fisheries, our sport-fishing economy and our way of life.”
