Midwest Water Year Precip Rundown
I've discussed during the talks I've given at farm meetings this winter season about the "water year" precipitation. The term "water year" is a U.S. Geological Survey term, and is defined as follows:
The term U.S. Geological Survey "water year" in reports that deal with surface-water supply is defined as the 12-month period October 1, for any given year through September 30, of the following year. The water year is designated by the calendar year in which it ends and which includes 9 of the 12 months. Thus, the year ending September 30, 1999 is called the "1999" water year.
With that in mind, here is a look at how the 2013 water year precipitation has fared across the Midwest. Colleague Joel Burgio compiled this information. And, looking from west to east in the region, we see a definite split in the precipitation totals from October 1 2012 through Monday, March 19 2013.
