What happened

The episode as NWS LOT wrote it up.

Drought conditions continued across much of northern Illinois during August 2005. Much of Illinois was declared an aqriculture disaster area in early August. Outdoor water restrictions and bans continued in many locations. Several wells dried up in Kempton Township in Kane County. The cities of Elgin and Aurora use water from the Fox River. Due to low flow and high temperatures, there were problems with high algae content. Some wells also dried up in parts of Lake County. River levels were too low on the Illinois River to handle barges which carry the crops.The Spring and Summer months of 2005 were the 4th driest on record at Chicago Ohare Airport and Rockford Airport. At Chicago Ohare, 10.18 inches of rain was recorded. Normal rainfall during this 6 month period at Chicago is 21.47 inches. At Rockford Airport, 12.92 inches of rain was recorded during the Spring and Summer. Normal rainfall during these months at Rockford is 23.15 inches.Some locations received above normal precipitation for August 2005 from very localized heavy thunderstorms. Many locations received below normal precipitation including, Aurora in Kane County, 1.42 inches; Chatsworth in Livingston County, 1.60 inches; Marseilles in LaSalle County, 1.72 inches; Ottawa in Lasalle County, 1.89 inches; Dwight in Livingston County, 1.90 inches; Plano in Kendall County, 1.96 inches; Morris in Grundy County, 1.98 inches; Bourbonnais in Kankakee, 2.00 inches; Wheaton in Dupage County, 2.08 inches; Lansing in Cook County, 2.09 inches; Joliet in Will County, 2.12 inches.
