Digitization of documents to be included in the CLIR water collection began last week at the Riverside branch of the National Archives and Records Administration (NARA). The first series digitized includes the project histories of the All-American Canal. Construction on the canal commenced in 1934 and concluded in 1944. The All-American Canal flows along the California and Mexico border where it provides water to several desert communities in
Southern California.
The maps below show the progress made on the canal during the years 1936 and 1937. Note the thick, hand drawn, red line which represents the completed sections of canal.
