The Sacramento Delta is an agricultural region in northern California with deep historic significance for Asian Americans. Asian American laborers were instrumental to the development of Sacramento Delta, transforming the swampy peat bog into one of the richest agricultural areas in California. Beginning in the mid-19th century, Chinese laborers constructed levees, dikes, and ditches along the Sacramento and San Joaquin Rivers before breaking the fertile soil to grow fruit and vegetables including pears and asparagus. Asian Americans continued a permanent and transient presence in the Sacramento Delta on farms as migrant farm laborers, permanent farmworkers, and overseers, and in the small delta towns such as Isleton that emerged as merchants, restaurant operators, boardinghouse operators, and other business owners catering to the local community.
