The California Delta Farms Collection consists of business correspondence (1910-1917); annual statements; balance sheets; dividend notices (1915-1917); a brief history of the California Delta Farms Corporation (1920); and a scrapbook on the Corporation kept by consulting engineer, Millard A. Klein (1924-1934).

In 1902 Los Angeles capitalist and insurance executive, Lee A. Phillips, acquired the Jones Tract in the Delta of the San Joaquin River. Out of this initial purchase grew the forty-two thousand acre holdings of California Delta Farms, embracing at one time: King Island, Bacon Island, Bouldin Island, the Rindge Tract and islands in Contra Costa County to the west. Phillips devoted many years to the project of reclaiming these acres and turning them into the most productive farm lands in California. To accomplish this goal, Phillips created California Delta Farms (1906) and served as its President for more than twenty years. The corporation sold capital stock in the amount of $8.5 million and $3.5 million in bonds.
