The U.S. Army Corps of Engineers has an aquatic house of horrors planned for invasive Asian carp threatening the Great Lakes.
The Brandon Road Lock on the Des Plaines River is where the U.S. Army Corps of Engineers plans a series of deterrents to keep invasive Asian carp from moving upstream toward Lake Michigan.CLEVELAND, Ohio -
There are four primary species of Asian carp that worry the Corps and others concerned with the health of the Great Lakes. A similar rerouting of the Calumet River is also part of the extensive waterway system west of Chicago. “We know we could push fish with boat motor sounds,” he said, but blasting those could be inefficient because it’s probably just certain frequencies the fish are responding to.A second layer of deterrent will be a curtain of bubbles rising from an air-filled pipe along the bottom of the stream.
Yet another technique to be employed later in the project’s development will be the ability to flush water downstream through the lock when boats pass through. The flushing would be designed to carry away any fish eggs or larvae floating in the water, Leichty said.
