What the reports say
Written by National Weather Service staff at the time of the event · public domain
Numerous reports from a variety of sources of flash flooding in the southeast part of the city of Lincoln. Rainfall reports of 3.5 to over 5 inches of rainfall were received. This along with areas of several inches accumulation of hail led to widespread street flooding in the area. Small streams and creeks in the area also overflowed including Stevens Creek. Water was flowing over the bridge where Holdridge Street crosses Stevens Creek. Severe water rescues were performed from stranded motorists.
Heavy rain caused flash flooding which caused extensive damage to basements and businesses and closed numerous county roads, mostly south of Lincoln, and especially along Salt Creek. Gravel was washed from roads and cropland was also flooded. It was estimated that resurfacing gravel roads alone would cost $180,000 and damage to homes and businesses could approach $1 million.
