A crew at Locks 27, the nation's busiest locks, removed a temporary high-water dam today as they prepared to reopen for barge traffic.
The St. Louis District, U.S. Army Corps of Engineers closed the locks June 3 as the Mississippi River level rose to 39 feet on the St. Louis gage, nine feet above flood stage.
"This is the busiest lock on the inland waterway system, and the economics associated with river transportation is huge. This lock is the critical point on the Upper Mississippi and Illinois Rivers," said Andy Schimpf, St. Louis District navigation business line manager.
