by Karl Plume (Reuters) – The lower Ohio River was closed to navigation on Tuesday at locks and dam 52 in Paducah, Kentucky, due to rising water on the key commodity shipping waterway, shipping industry sources said.
It was at least the third closure of that stretch of the river in the past two months and it was not yet known how long the busiest section of the U.S. inland waterways system would remain closed, they said.
A queue of 22 towboats hauling 209 barges loaded with commodities such as coal, grain, fertilizer and steel were waiting to pass through the area on Tuesday afternoon, according to U.S. Army Corps of Engineers data.
That queue is expected to build as more vessels arrive during the temporary closure.
The Army Corps, which manages and operates the facility, halted locking of vessels through its two lock chambers because the river’s water level had risen too high following recent rains, shippers said.
Most vessels would normally be able to pass over the lowered wicket dam during high-water periods, but a rock dike that was installed in the river as part of an emergency dam repair this autumn is preventing boats from safely passing, they said.
Army Corps crews will begin working to remove the dike on Wednesday or Thursday, a process that may take several days, American Commercial Barge Lines said in a daily industry report.
The U.S. Army Corps of Engineers could not be immediately reached for comment.
The Ohio River at Paducah has risen more than 3 feet (91 cm)in the past week to a gauge reading of 16.6 feet (5.06 meter), and is expected to peak at 24 feet (7.32 meter) next Tuesday, according to the latest National Weather Service river forecast. The gauge does not represent the river’s depth at that site but is instead used to measure water level changes over time.
