Lashed together with steel cables, bundles of trees dangled from a helicopter over the upper Ohio River, ready to become fish habitats. Twenty-nine tree bundles, removed in March from the location where the batch concrete plant is being built for construction work at Montgomery Locks and Dam, were placed into a slough 32 miles downriver from Pittsburgh on August 8. "Seeing a helicopter flying back and forth with a bunch of trees dangling from beneath it is something you don't see in Pennsylvania every day," said Matt Rother, chief of the Civil Design Section for the Pittsburgh Engineer District. The Corps coordinated the locations and spacing of the new fish habitats with the Pennsylvania Fish and Boat Commission and the U.S. Fish and Wildlife Service. |
