It’s official: the Northern Sierra “8-Station Index”–comprised of 8 precipitation observation sites in the northern half of the Sierra Nevada watershed–has eclipsed 1982-1983 to become the wettest Water Year (Oct-Sep) period on record! Even more remarkable is that this record has been set so early in the calendar year–even though May-September is the dry season in California, some additional precipitation in this region is all but inevitable in the coming months, which will push this record total even higher. Statewide precipitation metrics are not far behind. Precipitation in 2016-2017 is closely paralleling 1982-1983, and stands a good chance at breaking the long-standing record later this year.
