Eight days ago, snow-water-equivalent (SWE) in the Upper Henry’s Fork subwatershed was 91% of the long-term median. One snowy day and seven dry days later, Upper Henry’s Fork SWE is still at 91% of median. SWE is 120% of median in the Fall River subwatershed (down from 123% eight days ago) and 124% of median in the Teton River subwatershed (down from 130% eight days ago). Current forecasts call for near-average precipitation over the next five days, followed by below-average precipitation for several weeks after that.
Graph above shows percent-of-median SWE since November 1 in the three subwatersheds of the Henry’s Fork watershed. Also shown is the percent-of-median SWE for the Henry’s Fork and Teton Basins, as reported in the Natural Resources Conservation Service (NRCS) daily snow/precipitation report. Table below shows data for individual sites, as well as the subwatersheds and the NRCS Henry’s Fork and Teton Basins.
