12. Flood at Sidney, Nebraska, on 17 June 1947. A report of a flood
at Sidney, Nebraska, was received on 18 June. Investigation revealed that
2.5 inches of rain fell at Sidney between 5:00 p.m. and 11:20 p.m. on 17
June; the most intense portion of the storm occurring between 5:30 and
6,00 p.m. The storm runoff over-taxed the storm sewers in Sidney, flood-
ing the streets and many basements in low lying sections of the tovm.
This water damage was considered to be due to poor local drainage and,
therefore, no estimate was made of the damage. The above-normal discharge
on Lodgepole Creek, which flows through Sidney, did not approach flood
stage as a result of this storm.

13. Report of flood in Cheyenne, Wyoming, 20 June 1947. A report
was received of a damaging flood at Cheyenne, Wyoming, during the night
of 20 June. Subsequent investigation revealed that 1.76 inches of rain-
fall was recorded at Cheyenne between 3:55 p.m. on 20 June and 6:00 a.m.
, on 21 June; with 0.86 inches during the one hour period ending 11,00 p.m.,
20 June. In the lower portion of Cheyenne, where there are no storm
sewers, the storm runoff flooded'many basements and washed gravel from
the streets. These were the only damages that were reported as a result
of this storm.

. 14. Floods at Aurora, Colorado. On 7 July, 11 August, and again on
23 August, heavy local rains near Aurora, Colorado, caused the flow in a
small drain,which courses through Aurora, to back up and, for a few hours,
overflow West Colfax Avenue, a main thoroughfare. Each of these floods
was investigated and it was learned that there were no direct flood damages.
Traffic was interrupted on West Colfax for a short time during each flood.
