| 摘要： | Winter weather issues, including icing on the Illinois River and low water on the Middle Mississippi between St. Louis, Mo., and Cairo, Ill., are causing headaches for the navigation industry and the Corps of Engineers. At one point January 12, about 25 boats were waiting to lock through the LaGrange Lock, Mile 80.2 on the Illinois River. On January 9, locking was paused for 5-1/2 hours while a lock crew conducted operations to mitigate ice stacking on the dam. Chris Trefry, chief of water control at the Rock Island Engineer District, said the lock was closed after the supervisor at La-Grange Lock and Dam observed multiple wickets on the dam in a semi-breach position due to heavy ice flows stacking up on them to heights of 4 to 5 feet above the water line. |
