The Homer A. Halverson Collection documents water history and related infrastructure in the greater Los Angeles area from the early- to mid-20th century, especially the construction of containment and runoff systems within urban and suburban areas in the city. It consists primarily of photographs, but also includes magazine and newspaper articles, pamphlets, brochures, flyers, and other materials. The collection consists of two series: Photographic Materials (1915-1961) and Personal FIles (1928-1977).
Series I, Photographic Materials, documents the construction of water management systems and water-related infrastructure in the city of Los Angeles from the early- to mid-20th century, as well as existing water systems in the city and outlying areas, especially the Los Angeles River. It consists of photographs, negatives, color transparencies, and slides documenting various water-related construction projects and sites, in addition to those of numerous rivers, creeks, channels, reservoirs, and dams around Los Angeles. It also includes photographs of other Los Angeles infrastructure, especially freeways. The series dates from 1915 to 1961 and is filed alphabetically.
Series II, Personal Files, documents Halverson's interests outside of the water supply to Los Angeles, especially literature, drawing, and the western United States. It includes detached magazine covers, newspaper clippings, pamphlets, brochures, flyers, and other materials. The series dates from 1928 to 1977, and is filed alphabetically.
