The report that was done by the Great Lakes cities initiative is a wonderful report. It does outline three potential strategies for physical separation of the canal and has outlined the economic costs of implementing those options, ranging from between $3 billion to $9 billion.
These are strategies that come with a very significant cost. We have that report, but we also have a report that's being completed by the U.S. Army Corps of Engineers that's also identifying potential control strategies. We hope that report will be completed very soon. It's called the Great Lakes and Mississippi River Interbasin Study. That's supposed to come out soon too.
With those two reports, we can evaluate which strategies are the best approach for dealing with this.
What we've learned from the Great Lake cities report is that we're not just dealing with Asian carp. We're dealing with communities that live on the Chicago waterway system. The city of Chicago depends on that system for flood control and infrastructure and it involves transportation, so it has huge value. There is definitely a weighing and a balancing of impacts. Certainly we would like to see something more in the future than just the electric dispersal barriers currently in place.
