What happened
The episode as NWS PAH wrote it up.
This was the first of two major flash flood events. The second occurred on May 10. The combined effect of the two events prompted a federal disaster declaration for the county. Low-lying areas were evacuated, most streets were closed, and a dike collapsed in Marion's flood control project. The dike, which broke about half a mile south of Marion, flooded a farm field and three acres of land. Illinois Route 37 was closed near Johnston City.
