Flood Occurrences

Ana1yeis of climatological data and inspection

of the flood history for the Arkansas River subbasin above John

Martin Dam show that the most severe flood-producing storms occur

during the late spring or summer months. The spring season is the

transitional period between the occurrence of instability and fron-

tal activity and is subject to storms caused by both types of ac-

tivities or a combination thereof. Also, the movement and interac-

tion between airmasses during these seasons are more pronounced.

This may result in heavy spring snow storms in the higher elevations

Or in high intensity rains during the spring. These storms and the

physical features of the watershed can produce the rapid concen-

tration of runoff that characterizes flash floods of high peak

flows, small volumes, and short durations.
