In the B.C. days, meaning “Before Calculators,” doing math was arduous, time consuming and prone to error. Long unforgiving rows of multiplication, division to five decimal points, torture in that childhood wasn’t water-boarding, it was math without a calculator.
As I recall the time period, from fifth grade through calculus was lost in a sea of hand calculations, if maybe augmented by a slide rule, and trying to keep decimal points straight.
Google says … Portage County is 823 square miles, and part of an irrigated complex of 3,417 square miles in five Central Sand counties.
Rainfall average in Portage County is 32 inches. In 2013 the regional total was 27.22; 2012, 27.9; 2011, 34.9; 2010, 42.6; 2009, 31.5; 2008, 30.0; 2007, 29.6; 2006, 28.6; 2005, 30.4; 2004, 35.9.
I have a friend scientist who tells me central Wisconsin rain trends are near the average. Maybe it’s just the farm apprehension that makes it seem otherwise. But the century-long, 10-year average (courtesy of the Stevens Point waste treatment plant) is pretty dead-on at the 32 inches precipitation average.
An average that has everything to do with the subject of ground water management.
