What happened

The episode as NWS DVN wrote it up.

The drought of 2005 that started in July continued into September 2005 and October 2005. By September, the drought was affecting mainly hydrologic aspects and to a lesser extent agricultural. A report of the hydrologic issues affected by the drought is supplied by the service hydrologist.September precipitation averaged 2.7 inches which was 0.7 inches below normal. Departures from normal ranged from +0.1 inches (Burlington IA) to -1.7 inches (Dubuque IA). Precipitation percent of normal averaged 79 percent, with individual figures ranging from 103 percent (Burlington IA) to 54 percent (Dubuque IA). The three-month average precipitation departure from normal is -4.7 inches, or 60 percent of normal. September was the eighth consecutive month with an average deficit of precipitation. The twelve-month precipitation departure is -8.62 inches, or 76 percent of normal.Other River and Stream ConditionsStream flows began the month with streams in Iowa and Missouri mainly near normal (25th to 75th percentile), with a few reporting below normal (10th to 24th percentile) conditions. In Illinois, however, conditions were different. Most of the locations reported either below normal or much below normal (less than 10th percentile) flows. A couple locations were reporting record low flows for the day.Conditions remained nearly the same for the entire month. Some rain events brought a few locations in Iowa-especially in the western HSA-to above normal (76th to 90th percentile) conditions for a few days during the month. A significant rain event affected locations northwest of the HSA toward the end of the month. Runoff from this rain pushed rivers in the northwest HSA, such as the Wapsipinicon and Cedar Rivers, to above to much above normal (greater than 90th percentile) flows. No flooding was reported in the HSA, however. The month ended with locations in the northwest HSA experiencing above to much above normal conditions, while elsewhere conditions were near normal except for a few locations that reported below normal conditions.Stream flows again fell during the last third of the month, with conditions by the end of the month much similar to those at the beginning of the month.
