<br />DESCRIPrION
<br />
<br />2. The Arkansas River has its souroes in the Rocky
<br />Mountains in central Colorado and flows 1,450 miles generally south-
<br />easterly through Colorado, Kansas, Oklahoma, and Arkansas to the
<br />Mississippi River. From the source to Pueblo, Colo., 171 miles, it
<br />is a typical mountain stream. At Pueblo it enterS the Great Plains
<br />and flows over a sandy bed with low banks to Hutchinson, Kans., a
<br />distance of 400 miles, with an average slope of nearly 7 feet to the
<br />mile. The flow in this section is erratic. ,fuile destructive floods
<br />occur, portions of the stream bed run dry for considerable periods.
<br />Large areas adjacent to this section are under irrigation. From
<br />Hutchinson to Little Rock, Ark., a distance of 641 miles, the river
<br />flows through the rolling prairies of Kansas and Oklahoma and the
<br />rugged section 0 f western Arkansas. The average slope through this
<br />section is about 2 feet to the mile. Below Little Rock the valley
<br />is broad end merges into that of the llississippi River. The river
<br />length is 178 miles and the average slope 0.6 foot per mile.
