Collection contains a binder with the copies of the report written by assistant engineer I.S. Voorhees (misspelled on the cover). This copy has been used to digitize the report. The digital copy was placed in the Annual Project Histories Collection. The annual project histories included in the Klamath Waters Digital Library are digitized versions of the Annual Histories published by the U.S. Bureau of Reclamation from 1903-1964. The Klamath Project Annual Histories, Oregon - California, provide descriptions of the management of the project including: canal and dam issues and projects, fiscal year financials, contracts, land acquired, land leased, project organization charts, litigations, photographs, maps, and hydrographies. These documents help explain social, economic and agricultural changes over time in the Klamath River watershed of Oregon and California.
