Boxes 1 through 20 of the Claremont Heights Irrigation Company Papers consist of the records of the Secretary or Secretary-Treasurer, Board minutes, and other miscellaneous material related to the company. The most complete information about the Claremont Heights Irrigation Company’s financial records occurs from 1927 to 1948, when Kenneth B. Forbes held the position of Secretary. Since the Company also owned water stock in other private mutual water companies, some information, such as annual reports, can also be found for the Pomona Valley Protective Association, Adams and Garner, and Claremont Basin Mutual Water Company, Ltd. The papers also reflect local business activities in Claremont, Pomona, and Los Angeles. Boxes 1 through 14 cover the years 1913 to 1916. Boxes 15 through 20, which are composed mostly of cash books, ledgers and audit reports, cover the years 1913 to 1966.

Boxes 21 through 33 of the collection consist of materials and correspondence generated by the administration of the company and its closing and sale to the Southern California Water Company; financial records; and records generated by operational activities. Administrative documents include minutes of board meetings and annual stockholder meetings; notices sent to stockholders about meetings, assessments, rate changes, and the liquidation of the company; stock certificates and stockholder lists; blank forms; and correspondence. They also include the company’s articles of incorporation and amended by-laws, as well as legal documents and correspondence relating to lawsuits the company was involved in. The company’s financial records include bank statements, checks and check stubs, ledgers, tax records, financial statements, bills, and other related materials used in the company’s regular financial affairs. The operational materials document the company’s day-to-day water pumping and distribution activities and include records relating to its business partnerships with McCalla Brothers Pump and Drilling Company and the Valley View Water Company. Additional operational materials include meter and well reports, water permits, tract maps, and stereographic photographs of well interiors accompanied with two stereographic slide viewers. The collection also contains administrative files of the Claremont Basin Mutual Water Company and the contents of a letter box containing administrative records, financial records, correspondence, and a stock book belonging to the Valley View Water Company. This portion of collection came from the company’s president, Stanley R. Barnes, and documents the company’s annual meetings and related administrative activities particularly well. There are, however, significant gaps in its stockholder records.
