Predefined Maps: Station and Basin Conditions
To get you started with the Interactive Map, the following are links to predefined maps organized by data type. After opening a map, you can zoom to your area of interest, customize the map, and then bookmark the URL to save your settings. End of month maps include additional data from snow courses, cooperative precipitation stations, and other parameters that are not collected daily like SNOTEL stations.

Snow Water Equivalent (Daily)
Daily basin filled map showing snow water equivalent as a percent of normal (1991-2020). Daily snow water equivalent percentages are derived from SNOTEL data only.
Snow Water Equivalent (Monthly)
Monthly basin filled map showing snow water equivalent as a percent of normal (1991-2020). Monthly snow water equivalent percentages are derived from SNOTEL and Snow Course data.
