Severe flooding occurred on June 4, 2002, in the Indian Creek Basin in Linn
County, Iowa, following thunderstorm activity over east-central Iowa. The rain
gage at Cedar Rapids, Iowa, recorded a 24-hour rainfall of 4.76 inches at 6:00
p.m. on June 4th. Radar indications estimated as much as 6 inches of rain fell
in the headwaters of the Indian Creek Basin. Peak discharges on Indian Creek of
12,500 cubic feet per second at County Home Road north of Marion, Iowa, and
24,300 cubic feet per second at East Post Road in southeast Cedar Rapids, were
determined for the flood. The recurrence interval for these peak discharges
both exceed the theoretical 500-year flood as computed using flood-estimation
equations developed by the U.S. Geological Survey. Information about the basin
and flood history, the 2002 thunderstorms and associated flooding, and a
profile of high-water marks are presented for selected reaches along Indian and
Dry Creeks.
