The U.S. Fish and Wildlife Service has released a preliminary report of a study documenting how barge traffic impacts fish movement within the Chicago Sanitary and Ship Canal at the U.S. Army Corps of Engineers Electric Dispersal Barrier System. The preliminary results show that it is possible that barges moving downstream (away from Lake Michigan) can temporarily cause a decrease in the electric charge in the canal and cause water in the canal to reverse direction and flow upstream (toward Lake Michigan). These combined effects could increase the risk of small fish being able to move upstream through the electric barrier.
