This is a map-first SNODAS view for the Upper Colorado basin built from water-year packs instead of a single day. It uses daily pre-rendered SNODAS raster frames plus compact summary files of basin and sub-basin totals, so you can switch years, drag through the season, and see both the map and the numbers change together. The lower seasonal comparison now includes all locally available complete SNODAS water years, plus the current partial year to date.
