Spring Break-Up The best measure of break-up in Alaska is the Nenana River Classic which has made a lottery out of the event since 1917. Break up has been trending earlier since the mid 1960s and last spring there were records set across Alaska. The Nenena tripod fell on April 23rd, not a record but pretty early. From the archive see a LEO Post from Patricia Yaska in Chuathbaluk about the early Kuskokwim break-up on April 17, 2016. See also a great post about the impacts of jellyfish on the commercial salmon fishery last summer. Mike Brubaker - Editor
