The storm of August 27-28, 1977, in southwestern Oklahoma, shown on the map in figure 1, resulted in extensive inundation of property and damages estimated at close to $1 million (National Weather Service, 1977).
Major flooding occurred on Blue Beaver and West Cache Creeks and their tributaries in Comanche County near the communities of Cache and Faxon, Oklahoma. The area studied extends from the confluence of Blue Beaver and West Cache Creeks near Faxon, north to U.S. Highway 62 at Cache, Peak discharges at selected points along major streams in the area were computed and compared to estimated flood frequencies. Observed highwater marks were used to establish flood profiles and to map flooded areas . Rainfall amounts for the storm and depth-duration- frequency data for the area are included.
