California Cooperative Snow Surveys

California Snow Surveys

Historical
Course Data
A unit of the California Resources Agency, Department of Water Resources, Division of Flood Management.

Section 228 of the Water Code mandates that the Department collect snowpack, rainfall, and river discharge data, in order to forecast seasonal river runoff volume. This forecast is officially published in DWR's Bulletin 120. The data used in producing the water supply forecasts are provided by public and private cooperating agencies. The State has coordinated Snow Surveys since 1930, and we have been publishing our water supply forecasts on the World-wide Web since early 1994.

Hydrologic data are maintained by our sister section the California Data Exchange Center.

Selected presentions from the 2005 Cooperator's Meeting at Mt. Shasta City, CA are available.

The 74th Western Snow Conference meeting will be held in Las Cruces, New Mexico April 17-20, 2006 hosted by the South Continental Region. Further information is available from the Western Snow Conference.
