STUDY AREA DESCRIPTION Community Description Crowley is located in southeastern Colorado. It is located approximately 43 miles east of Pueblo. The area studied for the FHBM is the incorporated areas of the Town of Crowley as of August 15, 1975. Watershed Description The local drainage attributed to nearby irrigation canals can overflow during thunderstorm events through Crowley and lies within the Arkansas River Basin Subregion 1, as set forth in the Guidelines For Determining lOO-Year Flows For Approximate Floodplains and has a drainage area of less than 25 square miles. As a result, the basin size is less than the lower limit for the Arkansas River Basin Subregion 1, as set forth in the Guidelines For Determining lOO-Year Flows For Approximate Floodplains. Floodinl!: Problems and Floodinl!: Historv Convective type cloudburst storms sometimes lasting for several hours. can be expected to occur in the Crowley area during the summer months. The cloudburst storms can cause high peak flows with a small water volume over a short duration. Flooding has occurred in Crowley as recently as the summer of 1995 due to such storms. The local drainage attributed to nearby irrigation canals is shown on the Crowley FHBM and has been a source of local flooding problems in the past. Flooding from general rainstorms may also occur during the months of June through September. General rainfall flooding is characterized by higher peak flows with a moderate volume and a moderate duration. Flooding is more severe when antecedent rainfall has resulted in saturated ground conditions or the ground is frozen and infiltration is minimal. Research of the study area yielded minimal information regarding major flooding events in Crowley. In spite of the long history of human activity in Crowley County, there are no historical accounts of major flooding in Crowley. There have been, however, occurrences of high water in the past.
