Early farming was concentrated close to the Sacramento-San Joaquin Delta, where the water table was high year round and water transport more readily available, but subsequent irrigation projects have brought many more parts of the valley into productive use. For example, the Central Valley Project was formed in 1935 to redistribute and store water for agricultural and municipal purposes with dams and canals. It was intended to serve smaller farmers, with a 160-acre maximum size limit. However, this was largely ignored under pressure from large landowners. The even larger California State Water Project was formed in the 1950s and construction continued throughout the following decades.
