Hello Southern California water enthusiasts!


I would like to share with you the Digitizing Southern California Water Resources project web page!  The Digitizing Southern California Water Resources project, also known as the CLIRWater project, is a 3-year collaborative preservation and dissemination project supported by a Digitizing Hidden Special Collections and Archives grant from the Council on Library and Information Resources (CLIR) and funded by the Andrew W. Mellon Foundation.  You can visit the new CLIRWater project web page here: https://library.claremont.edu/scl/clirwater-project/.


One of the project objectives is to unearth a critical mass of 19th- and 20th-century primary source documentation on the development, management, and exploitation of Southern California and western United States water.  This project is a partnership between The Claremont Colleges Library; the A.K. Smiley Public Library in Redlands (CA); the Oviatt Library at California State University, Northridge (CSUN); the Water Resources Institute at California State University, San Bernardino (CSUSB); the National Archives and Records Administration (NARA) at Riverside (CA); the Ontario City Library (CA); and the Upland Public Library (CA).


Since 2017, students from The Claremont Colleges, CSUN and CSUSB, have been digitizing and describing reports, maps, blueprints, photographs, and other materials found in water-related archival collections held by the partner institutions.  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.
