From the Lawrence Daily Journal-World for Sept. 28, 1973:
Heavy rains had hit parts of Kansas today, drenching some areas that had already been battered by tornadoes earlier this week. Serious flooding was reported on the Saline, Smoky Hill, and Solomon rivers, where hundreds of people were evacuated from their homes. In Lawrence, more precipitation was in the forecast today after storms had brought 1.81 inches of rain, swelling the Wakarusa and Kansas Rivers and Mud Creek and swamping county and township roads. Several streets in North Lawrence and areas south of 23rd Street remained closed this morning due to flooding. City officials said that damage to city streets and drainage systems could not be estimated until the water cleared.
The Douglas County disaster siren warning system was to be tested at noon this Saturday provided the area was not in a severe weather warning area. H. H. Belote, county civil defense director, said that it had been the policy to test the sirens only in clear weather, but that had been changed and the system would be tested "in rain, sleet or snow" as long as no actual warnings had been issued.
