N2 - Drought begins with a reduction in precipitation, but different kinds of precipitation deficiency episodes (duration, intensity, and areal extent) create varying problems for drought-sensitive activities; an agricultural droughttypically is not a water supply drought. Shared characteristics of precipitation deficiency events and related surface water supply problems in Illinois were used to define climatological characteristics of precipitation deficiency droughts that cause problems for water supply systems. The temporal and spatial characteristics of these water supply precipitation droughts were assessed revealing that droughts typically: (a) begin in warm season months; (b) become more widespread when more severe and/or of shorter duration (although all droughts could be expected to cover at least 75%-85% of the state); (c) are more severe and frequent in central Illinois; and (d) end with much above normal precipitation in the initial post-drought months, but tend to recess to slightly drier than normal conditions (but not drought levels).
