Volunteers learn how to measure how much water is contained in the snowpack, known as snow-water equivalent (SWE) at the SNOTEL site at the top of McClure Pass in March 2018. Water managers are gaining a better understanding that what happens in the weeks after peak snowpack in the spring can have an outsize influence on the yearâs water supply.

Scientists studying water supply focus on weeks following peak snowpack
Water managers in the Colorado River basin are gaining a better understanding that what happens in the weeks after peak snowpack — not just how much snow accumulated over the winter — can have an outsize influence on the year’s water supply.
Water year 2021 was historically bad, with an upper basin snowpack that peaked around 90% of average but translated to only 36% of average runoff into Lake Powell, according to the U.S. Bureau of Reclamation. It was the second-worst runoff on record aft...
