DWR Snow Survey March 26DWR's fourth 2008 winter snow survey will take place at 11 a.m. Wednesday, March 26, 2008, near Lake Tahoe.

Under the authority of California Water Code Section 228, the Snow Surveys Section administers the California Cooperative Snow Surveys Program, coordinating and receiving snow and related data from cooperators, and issuing forecasts of runoff from major snowmelt watersheds. These forecasts are officially published in DWR's Bulletin 120. Hydrologic data used in producing the water supply forecasts is maintained by fellow section, the California Data Exchange Center. The State has coordinated Snow Surveys since 1930, and we have been publishing our water supply forecasts online since early 1994.
