REMARKS

6.4" fell in 4 hours

2.25" fell on 15th and 16th

The above table might be put in perspective by realizing that a_;
6-hour rainfall that would occur once each 100 years would drop 3.5
inches. Approximately three-quarters of the basin received rainfall
in excess of that figure.

Because of the flood control measures in effect, as later described,
and the much smaller rainfall, this flood did not have near the effect as
the 1935 flood. All of the bridges crossing the creek, however, were
washed out at the abutments, stranding numerous travelers. The damages
from the flood were estimated to be $169,165 above Kiowa.

4. Magnitude of Previous Storms

The State Engineer and others have computed the magnitude of the
major storms on Kiowa Creek by measurement of the stream at the highwater
marks, which may be summarized as follows.

All of these floods are considered to be in excess of that which
might be expected to occur on an average of once each 100 years.
