Officials are advising boaters to stay off the Mississippi River from Clinton in eastern Iowa down to the Missouri border.
The state Department of Natural Resources announced Wednesday that the water is above flood stage with a strong current that makes for a hazardous situation. The high water was caused by recent flash flooding in northeast Iowa.
State Conservation Officer Ed Kocal says they're advising against boating until the water level drops several more feet. That could take weeks.
Two people were towed from the Mississippi River Tuesday after their boat lost power and drifted down the river at a rapid pace with no control.
