The greater Chicago land area wa 1.35" under the average last year. May of 2002 was one of the 5 wettest in Illinois.
Our problem was and still is not getting metered amounts of rain.
Baldwin is blanketed with snow, The Berrian area of I 94 just (Friday) had a blizzard and is covered. The UP has it's normal snow pack. East coast is rocked with snow.
Our little part of the world is not. Its all around us, most likely reason is the green house gasses from the metropolis we live in.
Give it time before you start hoarding water and praying for rain, March, April, and May could suprise us.
Worst low water was 1988, many people died that summer due to heat stroke.
