<br />Flood History, Floods in the Kiowa Creek basin are caused by runoff from intense thunde['storm rainfall.
<br />Knowledge of historical floods is limited to three major events, These events are discussed below,
<br />
<br />Flood of 21 May 1878. No precipitation or discharge estimates are available for this flood, However, data
<br />presented in the United States Geological Survey Water Supply Paper No, 997, entitled "Floods in Colorado"
<br />indicates that a substantial flood did occur, The above publication reprinted the following article taken from the
<br />Colorado Magazine of July 1937: "Among the unsolved mysteries in Colorado's history is the disappearance
<br />of a standard gage Kansas Pacific (now Union Pacific) locomotive in the quicksands of Kiowa Creek on the
<br />night of May 21 ,1878. A sudden flood had destroyed the wooden bridge that crossed the usually dry channel
<br />a short time before a freight train was due, and owing to the bridge being the low point of a sag in the roadbed
<br />and (to) the high speed of the train, the engine and most of the cars plunged into a swirling torrent of water
