Board of Commissioners Reports (1926-1934)

Background

Beginning in 2017, students from The Claremont Colleges, California State University, Northridge (CSUN), and California State University, San Bernardino (CSUSB), have been digitizing reports, maps, blueprints, photographs, and other materials found in water-related archival collections.  Subjects covered by the collections include floods and flood plains, irrigation, legal cases, the Colorado River Aqueduct, the Los Angeles Aqueduct, reservoirs and dams, the Salton Sea, water companies and municipal water suppliers, water engineering, water rights, and land ownership.  The materials come from a variety of sources such as federal, state, and local governments, water companies, local agencies, engineers, and other individuals involved in water development in the Southern California region from the 19th through the 20th centuries.

This collaborative preservation and dissemination project (titled: Digitizing Southern California Water Resources) is supported by a Digitizing Hidden Special Collections and Archives grant from the Council on Library and Information Resources and funded by the Andrew W. Mellon Foundation.
