"MEMPHIS, Tenn. -- Nearly 100 boats and barges were waiting for passage Monday along an 11-mile stretch of the Mississippi River that has been closed due to low water levels, the U.S. Coast Guard said."
"New Orleans-based Coast Guard spokesman Ryan Tippets said the stretch of river near Greenville, Miss., has been closed intermittently since Aug. 11, when a vessel ran aground.
Tippets said the area is currently being surveyed for dredging and a Coast Guard boat is replacing eight navigation markers. He says 40 northbound vessels and 57 southbound vessels were stranded and waiting for passage Monday afternoon.
Tippets said it is not immediately clear when the river will re-open."
