The episode as NWS OUN wrote it up.
Summary of events of July 19, 1997:Slow-moving nighttime thunderstorms containing torrential rain moved across northern and central Oklahoma. With the ground already at or near saturation across much of the area, these thunderstorms triggered widespread flash flooding, particularly in north-central Oklahoma. Primarily in Garfield and eastern Major Counties, Turkey Creek, Indian Creek, and Sand Creek and their tributaries that normally only contain a scant foot of water swelled to 8 to 10 feet deep in less than 3 hours. Long time area residents could not recall a time when these creeks had ever been higher or risen as fast. Flood damage to county roads and bridges in these two counties was extensive, topping the million dollar mark. See preceding individual Storm Data entries for further details and additional reports.
