Year-over-Year Comparison

Highlights

  1. The Core Supply region added 1.66 inches in April, bringing the Water Year total to 88.95% of normal, just shy of the forecasted range. While that's well below March’s contribution, how does it compare historically? Over our 8-year data record, this April ranks fifth for precipitation accumulation—right near the middle. Fitting, for a year that’s been all about “average.”
  2. With April’s accumulated precipitation, this year remains between the traces for analog years of 2017-18 and 2018-19. The plot below shows the Statewide precipitation for the current water year (26.25” through the end of April).
