TWENTIETH ANNUAL YEAR BOOK— PART VIII 711 



by the storm of July 9, 1919, and probably by the storm of July 4-5, 1876. 

 The storm of October 4th gave a total of 3.38 inches, as compared to a 

 total of 3.87 inches on July 9th. Rainfall was not remarkable on either 

 date for "total" amount, but for intensity of fall within an hour. 



During the week preceding the storm of October 4th the weather was 

 continuously unsettled, with thunder showers every day. The week be- 

 ginning September 28, 1919, in fact, was the wettest "first week in Octo- 

 ber" on record at this station, utterly spoiling the Fall Festival then in 

 progress at Dubuque. 



The great downpour occurred between 3:13 P. M. and 4:39 P. M., 90th 

 meridian time, and was preceded by and followed bj' light rain. Rainfall 

 was excessive from 3:18 P. M. until 4.38 P. M., and accumulated amounts 

 during this period were as follows:

The storm of October 4th was more local in character than that of July 

 9th, and the area of heavy rainfall did not extend to Union Park, where 

 great damage resulted on July 9th. Intense rainfall, however, fell over 

 the entire city, causing great damage to brick pavements on water-way 

 streets. The effects of the storm within the city limits were practically a 

 repetition of what occurred on July 9th. 



The brick surface of Eighth, a steep water-way street, was again ripped 

 off for several blocks. Seventeenth and Twenty-second streets experienced 

 similar damage, as on Eighth, though much less steep. Seventeenth was 

 not much damaged on July 9th. Kaufmann avenue was in process of re- 

 paving due to damage from the storm of July 9th, and much of the new 

 work was ruined as before, causing heavy loss to the contractor. East of 

 Clay and north of Sixteenth, a flat, residential section two or more blocks 

 wide and more than a mile long, became a temporary lake during the 

 storm and scores of cellars in this section were flooded and considerable 

 property damaged. 



There was other damage of a less serious nature in various parts of the 

 city. The bathing beach property at Eagle Point, for instance, was much 

 damaged for the third time this season. Losses outside the city were not
