TRAVERSE CITY, Mich. (AP) — Members of Congress are calling for quick action at a crucial spot in the Chicago area to block Asian carp from reaching the Great Lakes.

Legislation introduced Thursday would order the U.S. Army Corps of Engineers to take steps such as placing carbon dioxide bubble screens, underwater sound cannons and other devices at the Brandon Road Lock and Dam to repel the invasive fish.

The lock and dam on the Des Plaines River is considered a choke point where authorities could prevent the carp from reaching Lake Michigan, about 40 miles away.

Sen. Debbie Stabenow and Rep. Candice Miller of Michigan are sponsoring the bill, which also authorizes the Corps to find a long-term solution to the threat of invasive species crossing between the Great Lakes and Mississippi River watersheds.
