California Water Resources Development Map

Rare map of California, illustrating ongoing irrigation projects in California, published by the Irrigation Districts Association of California. 

First issued in 1951 and revised 5 times over the next 2 decades, the map was intended as an educational tool providing "a comprehensive picture of water resources development in California."

The map is a topographical effort to show major water development systems and their general relationship to the geographic features of the State.  Inclusion of any single feature, completed or proposed, does not imply endorsement by the Irrigation Districts Association . . .
