CHICAGO (WTAQ) - The best chance of keeping Asian carp out of the Great Lakes would be to install a series of dam-type structures on Chicago area waterways.
That's according to a new study released Wednesday.
It estimates the likelihood of 17 options to stop the bloated carp from threatening native fish in the Great Lakes. Notre Dame University, the U.S. Forest Service, and Resources for the Future said it prepared the study to speed up a decision by the federal government on what to do.
Earlier this month, the Army Corps of Engineers spelled out eight options for keeping Asian carp away. They would take up to 18 years at a cost of up $25 billion.
At a recent public hearing in Milwaukee, environmentalists said the government does not have 18 years to get something done -- and the challenge is much more urgent.
Wednesday's study showed that a physical separation of the water links between Lake Michigan and the carp-infested Mississippi River would have the most success. It could prevent 95 to 100 percent of carp from entering the Great Lakes.
A series of electronic barriers like the one west of Chicago are the next likeliest to succeed, at 85 to 95 percent. The report also said a combination of bubbles, strobe lights, and noise-makers would be 75 to 95 percent effective.
