According to this article in the Daily Southtown, officials are so pleased with the success of a temporary electric barrier in the Chicago Canal, used to keep Asian carp from invading, that they have decided to build a permanent barrier. The new barrier, which will cost $7 million, will be paid for by the Illinois Department of Natural Resources and the U.S. Army Corps of Engineers, and is built to last 30 years...will it be enough?
