Information for Water Managers

Historically, the principal audience for snow survey information has been hydrologists, watermasters, and analysts in agricultural and municipal water districts, environmental engineering consultants, and organizations whose operations are highly dependent on the State's water supply. Moreover, many such agencies cooperate with the Department of Water Resources in obtaining snow survey data, through contributions of time, personnel, funding, or all three. In recognition of this, the Snow Surveys website will primarily support activities of such agencies.
