The California Water Atlas is the product of a 15-month project sponsored by the Office of Planning and Research in cooperation with the Department of Water Resources. A team of researchers based in the Office of Planning and Research assembled the basic data and detailed information for the preparation of maps from a wide range of local, state, and federal sources throughout the state. This material was then relayed to a team of cartographers assembled at California State University, Northridge, where the finished maps were developed. The narrative sections were prepared by experts in each of the many topics treated in the volume. And the project as a whole operated under the guidance and supervision of an advisory group composed of the most prominent figures in the fields of hydrology, engineer-ing, history, book design, environmental protection, and water law.
California Water Atlas is considered a landmark atlas of 20th century, appreciated for its innovative visualisations and overal complexity.
