Past IEM Features tagged: wateryear
The water year covers a period from 1 October until 30 September of the next year. The thought is that precipitation after the first of October goes toward next year's plant use and snowfall equates into runoff during the next spring. The featured chart presents the water year precipitation totals along with the year over year change in this total. This year's total represents the third largest drop in precipitation. Of course, the largest was 1994 after the epic rains of 1993.
