Asian Carp Barrier Not Enough?

The U.S. Army Corps of Engineers is building a nine million dollar electric barrier to keep Asian carp out of the Great Lakes. But now the Corps is warning the fence in Romeoville, Illinois, might not be enough. The Great Lakes Radio Consortium’s Lynette Kalsnes reports:


The Army Corps is building the electric barrier in the Chicago Sanitary & Ship Canal. But the Des Plaines River runs near the canal, and it often floods in the spring. Chuck Shea is the project manager for the Army Corps of Engineers. He says they might need to build a flood wall or levee so high waters can’t sweep fish past the new barrier.


“It’s possible that water from the Des Plaines River could run into the Chicago Sanitary and Ship Canal. And if it was a large enough flood and there were fish in the right place, they might be able to use that as a pathway to enter the Chicago Sanitary and Ship Canal.”


Shea says while this possibility is unlikely, it still will be an important issue to study down the road. He says the more pressing concern is that an existing temporary barrier could wear out before construction on the permanent barrier is finished.


Asian carp have been spotted about twenty miles downstream from the electric fence. The giant fish are considered a threat to sport and commercial fishing. Shea says state officials are working to find money for the last phase of the electric barrier project.
