(Clarksville, MO) The Mississippi River is expected to crest in some spots today.
The river has reached 10 to 12 feet above flood stage. People along the river banks in Illinois and Mississippi have evacuated.
In Missouri, Gov. Jay Nixon has declared a state of emergency.
The National Guard has been called in to help build temporary flood walls to protect towns. Dozens of people also filled and stacked sandbags to protect the historic part of Clarksville.
The river has begun to recede there, but waters are flowing down the Mississippi.
Major flooding is not expected in Memphis, but a rainstorm over the next few days could change that prediction.
In 2011, the river crested in Memphis just short of the record set in 1937.
