Lock Operator Kenneth Hammock monitors a recreational sailboat as it moves barges into Chickamauga Lock March 2, 2023. He works to safeguard navigators at the active lock on the Tennessee River, which is very close to a U.S. Army Corps of Engineers Nashville District construction project to build a new 600-foot-long by 110-foot-wide lock.
