Noise, more electric barriers proposed to stop Asian carp in Great Lakes region

A long-awaited report held up by the Trump administration and set to be released Monday will tentatively recommend using noise, more electric barriers, water jets and other means to stop the spread of Asian carp in the Great Lakes region.

While the so-called Brandon Road Report itself will not be released until Monday, a copy of the notice of its release and call for public comment was posted on the Federal Register’s public inspection website today and includes details about the report.

The report identifies six potential alternatives for slowing the spread of invasive species of Asian carp at a key choke-point at the Brandon Road Lock and Dam along the Des Plaines River in Joliet, Ill., the notice says. The “Tentatively Selected Plan” is for using nonstructural measures including water jets, complex noise, electric barriers and more. Click on the following sentence to access the full story.

There have been strong indications from field studies done in recent years by the University of Minnesota Duluth and the U.S. Geological Survey that complex noise — which could sound like so-called “white” noise to a human — can be successful in largely stopping the spread of invasive species known as Asian carp.
