Asian carp study recommends noise and electric barriers to stop Great Lakes invasion

Noise and electric barriers are likely the best option for preventing Asian Carp from entering the Great Lakes through Chicago Area Waterway System, the U.S. Army Corps of Engineers recommends in a long-awaited study on halting the advance of the invasive fish.

That’s the top recommendation of a long-awaited study on the threat of the highly invasive fish, finally release today, months after it was complete.

And a coalition of environmental groups, while promising to review and comment on the recommendations immediately urged the corps to “move quickly from study to implementation of additional protection measures at the Brandon Road Lock and Dam, a logical choke point in the system.”

In a joint, written statement released this morning, those groups -- Joint Media Statement from Alliance for the Great Lakes, Natural Resources Defense Council, Prairie Rivers Network, Sierra Club, Illinois Chapter – also criticized the delay as putting the Great Lakes at unnecessary risk.

Additionally, the groups urged the corps to consider the broader issue of damage from invasive species in the region.

“While possible control measures at Brandon Road Lock and Dam represent another step in the fight against the upstream movement of Asian carp, we cannot lose focus on the need for a two-way solution that also addresses invasive species moving from the Great Lakes into the Mississippi River basin,” the groups said in the joint, written statement.

The corps is now taking comments on the recommendations.

The 45-day public review period runs through Sept. 21. Comments will be accepted through the project web site at http://glmris.anl.gov, by letter and at public meetings. Public meeting dates and locations are to be determined.
