Welcome to the California Cooperative Snow Surveys (CCSS) Program website. Here we bring together data from a variety of sources to allow viewers to obtain a quick view of the state’s snowpack conditions at the statewide and regional level.

The website includes basic information about the CCSS program, B-120 forecast verification, snow production comparison, and other resources. The snow survey data includes daily snow senor data and monthly snow course data that stored in CDEC database.
