And here's a short explainer on aurora colors! 🎨
Aurora color guide! What creates the different shades?
Different atoms getting "excited" at different altitudes
The bright reds are a sign of a particularly intense event

TL;DR: water years follow the natural cadence of the water cycle from snowpack buildup to runoff.
So while Oct marks the start to "spooky season" for many of us, your local water managers, hydrologists, and climatologists will be celebrating the "new year" with fresh water supply accounting.🎉[7/7]

The water year also aligns nicely with patterns in streamflow. It captures the gradual increase in runoff throughout the spring, followed by summertime peak, then the gradual decline in late summer/early fall. [6/7]

Starting the water year on Oct 1 means we account for most (if not all) of the winter snowpack.
This graph of water year snow water equivalent (SWE) at Fremont Pass shows this well. Look how much water would be unaccounted for during the spring runoff if we only started counting on Jan 1! [5/7]
