The U.S. supreme court refused immediate closure of shipping structures near Chicago to contain the Asian Carp, and authorities claim DNA from the invaders has been found in Lake Michigan for the first time. The court rejected Michigan’s request for a preliminary injunction to shut the locks and gates temporarily while officials and interest groups debate a long-term strategy. Despite this information we will win this fight said Gen. John Peabody of the U.S.Army Corps of Engineers in a teleconference Agencies will use netting and electrical stunning to search for live or dead fish while continuing to process hundreds more DNA samples. He said the discovery did not change the Army Corps view that the locks and gates on the Chicago Sanitary and ship canal and other waterways should remain in operation. Closing them would be inadequate to the task and the locks are leaky and there are other pathways around them.
