Below is the link to the Snow-to-Flow interactive graphic for Dotsero.
The post article mentioned 1977, 2002 and 2012 so I activated those years just to see how much worse they were. Gee, things could be worse than 2018.
NOAA' 6-10 and 8-14 Outlooks put the central Rockies into above average precip but well above average temps. Hence, we are not likely to get any May SWE kick like dismal year 1981 which looks to have been salvage by late spring dumps.
Year 2000 and 2001 looked like the most similar year to our current situation. Almost identical SWE and flow. They also looks like they had some late May early June high country rains(by interpretation) that added persistence to the runoff.
But squiggles on a screen can't possible tell the whole story but it will be interesting to see how similar, postmortem, 2018 is to 2000 and 2001.
