Col. Adam Czekanski, commander of the U.S. Army Corps of Engineers Pittsburgh District, pretends to press a button marked “Do Not Touch” at a lock and dam facility in Pittsburgh. Czekanski plans on visiting all 41 facilities within the Pittsburgh District by the end of October, which includes 16 flood-control reservoirs, 23 locks-and-dam sites, a warehouse on Neville Island, and the main office, spread across the district’s 26,000-square-mile footprint.
