One of the elements that played a key role in determining water supply to a majority of the cities in California between 1918 and 1930 was the distribution of water that was conserved from rainfall. Digitizing rainfall records from various places such as Santa Rosa, the Tenaja Station, the Pauba Ranch and the Nigger Canyon gave me a perspective on how water was distributed to various parts of California based on the regions’ seasonal rainfall. Regions with higher rainfall records would get lesser supply over a year compared to ones where the weather was mostly dry. Letters sent between the Los Angeles Chamber of Commerce and Willis S. Jones was an eye-opener as to how the prices were negotiated.
