WRCA Collections

Today, the Water Resources Collections and Archives consists of more than 200,000 technical reports, 1,500 specialized newsletters, over 5,000 archival maps, and hundreds of videos. In addition, WRCA manages over 200 archival collections, and has more than 100,000 historic photographs and aerial photographs that document the history of water development in the West. The primary access point to the WRCA collections is the Scotty Catalog.

Archival Collections

WRCA maintains hundreds of manuscript collections donated by hydrologists, engineers, academics, NGOs, and consulting and government agencies. The collections are made up of reports, personal papers, corporate records, correspondence, data, news clippings, maps, photographs, and other archival materials. All of WRCA's manuscript collections are discoverable via the Scotty Catalog; many of them have detailed collection guides via the Online Archive of California; and users can also peruse an alphabetical list of all WRCA manuscript collections.

Digital Materials

  • Digitized Images & Publications: Due to succesful grant projects, WRCA has digitized thousands of images and publications. Digital images are discoverable via WRCA's archival collections guides, and digitized text is discoverable from the Scotty Catalog.
  • eScholarship: WRCA administers an online eScholarship repository, hosting scanned and born-digital publications produced by UC faculty and graduate students. Users can search eScholarship or browse the Water Resources Center (UC faculty) reports and UCB graduate student and faculty publications. These items are discoverable in the Scotty Catalog, and, in most cases, a hard copy is held by WRCA.
  • CONTENTdm: Digital content from WRCA is available online.

Map Collection

WRCA has an extensive collection of historic and current maps related to coastal and inland water sources, as well maps illustrating irrigation districts and other boundary-related entities. Search for WRCA maps in the Scotty Catalog.

Oral History Collection

The University of California began a California Water Resources Oral History Series in 1965. These histories document historical developments in California's water resources by interviewing individuals who played prominent roles. WRCA owns published transcripts of these interviews, and many are available online.

WRCA's holdings also include print and DVD oral history interviews of prominent individuals from the California Department of Water Resources, U.S. Bureau of Reclamation, and the U.S. Army Corps of Engineers.

Photograph Collection

WRCA's archival collections include more than 100,000 photographs and slides, documenting water resources development. Collections that include a large number of images, include: Cooke, Cooper, Derleth, Eastwood, Galloway, Huber, Hyatt, Lee, and Lippincott. Images are discoverable via WRCA's collection guides.

In additon, WRCA hosts two catalogs of images collected and donated by Prof. Robert L. Wiegel, the Catalog of Coastal Aerial Photographs and the Robert L. Wiegel Coastal Slides Catalog.
