Frank Adams was deeply connected to irrigation and created Bulletin 21, Irrigation Districts in California which was a standard sourcebook for irrigation district history. He was raised in Santa Cruz and San Francisco and his father was interested in farming and organized a cooperative fruit exchange. Adams graduated from Stanford University in 1901 with a degree in economics and sociology and later received a master's degree from the University of Nebraska. After receiving his M.A., Adams went to work for Dr. Elwood Mead who persuaded him to try measuring water flow. This led to Adams pursuing a career of irrigation in the Division of Irrigation Investigations in the California offices. He was involved in irrigation investigations in California from 1910 to 1924 and he also was a Professor of Irrigation at UC Berkeley. In 1926 he became a consultant for the Bureau of Reclamation and participated in the organization and development of irrigation districts. He also worked with farm organizations and the Economic Research Council around various irrigation projects. Adams was involved in redrafting the Soil Conservation Act and the Central Valley Project and worked with various organizations regarding water across California. In this interview, Adams discusses his family history, time at Stanford, early work with Dr. Elwood Mead, Reclamation act of 1902, irrigation investigations, time at UC Berkeley, work with the State Conservation Commission, work with irrigation districts and various other organizations.
