Flooding on the Canadian River
The Canadian River had three different gages exceed flood stage as a result of the heavy rainfall August 18-19. Some of the gages went into major flood stage. All three of the gages experienced crests that were in the top five highest of all time at their respective stations. Several of the stations (Bridgeport and Union City) have not experienced crests that high in the past half-century. Bridgeport had a record crest, which broke a record that had been held since 1914, or for 93 years! The "impact descriptions" provided were taken from the AHPS website and describe theoretical conditions at a certain river stage at a given location.
