Dry Conditions Continue to Intensify
Updated on Tuesday, June 12, 2007
Next Scheduled Update on Friday, June 15, 2007
Since May 1 of this year, below normal amounts of rainfall have been recorded across all of Central Indiana. The least amount of precipitation during this time period came from Rushville, where 0.76 inches of rainfall fell. The highest reported amount since May 1 comes from an observation station located six miles northwest of West Lafayette, where 4.50 inches were measured.
These extremes were indicative of a pattern where most of the rainfall since May 1 has come in the form of scattered shower and thunderstorm activity. Widespread heavy rain has been rare, and the only sites that have recorded significant amounts of rainfall have been those locations that happened to be impacted by one of the scattered storms.
Outside of the two extremes mentioned above, all other sites reported between 1 and 4 inches of rainfall during the time period.
Because of the lack of rainfall since May 1, the June 5th release of the U.S. Drought Monitor indicated Abnormally Dry (D0) conditions across all of Central and Southern Indiana. Only extreme northern Indiana was not part of the abnormally dry conditions.
Moderate Drought (D1) conditions were present in extreme southern Indiana.
Due to a significant surplus that existed from late 2006 into the first few months of 2007, drought conditions have not yet significantly impacted groundwater levels.
Local Area Impacted:
Abnormally Dry (D0) conditions were present in all counties in Central Indiana.
State and Local Actions:
Local water company advising residents to use water wisely.. Some areas request people with an even address number water on even days of the month and those with an odd address number water on odd days of the month.
Since May 1, 2007, precipitation deficits ranged between two and four inches across Central Indiana.

Groundwater levels have not yet been significantly impacted during the current period of abnormal dryness. Detailed infomration courtsey of the U.S. Geological Survey is at http://watermonitor.gov/?a=groundwater
River and Stream Flow Conditions:
With well below normal amounts of precipitation since May 1, levels on area rivers and streams have fallen. The map below indicates the comparison of current flow levels to normal conditions for this time of year.
The six to ten day outlook, covering the period of June 18th through 22nd, indicates temperatures near or below normal across Central Indiana. The Precipitation Outlook indicates near normal precipitation across Central and Southern Indiana, with above normal precipitation across Northern Indiana. During this time period, normal precipitation is about seven tenths of an inch.
Further out in time the eight to fourteen day outlook, covering the period of June 20th to 26th indicates near normal precipitation and below normal temperatures. Normal precipitation for this period is about one inch.
Thirty and ninety day outlooks call for equal chances of below, above, or near normal values of temperatures and precipitation.
