Book excerpt: Excerpt from Progress Report San Joaquin Valley Drainage Investigation Quality and Treatment Studies Through December 31, 1967: Bio-Engineering Aspects of Agricultural Drainage Centuries ago, man learned to divert water and irrigate his land. However, he did not recognize the need to dispose of the salt laden waters that resulted from this irrigation. Many of the fertile lands that were irrigated by ancient man had to be abandoned because of the accumulation of salts in the soil. The ancient irrigators were in no way unique. In West Pakistan, salinity and water logging problems, which have developed during the last 20 to 40 years, have caused approximately acres of land to go out of production each year. In our own state, the early farmers of the Imperial Valley did not provide for land drainage, and many of them went bankrupt. The San Joaquin Valley is not immune to drainage problems either. Many sporadic attempts have been made to resolve them on a local scale since the early l900's. None of these attempts resulted in the necessary master plan for the removal of salt from the basin. When the waters of the San Luis Unit of the Federal Central Valley Project and of the State Water Project are applied to the lands of the Valley, the drainage problems will multiply and intensify.
