The City of Isleton was founded in 1874 by Josiah Poole. It is one of the oldest historical towns nestled along the beautiful Sacramento River Delta where fishing, camping, historic tours, farming, wine tasting, and bike riding is prevalent.
Around 1875, Chinese and Japanese mass immigration began to Isleton because of the agricultural jobs. Isleton Main Street was divided by the Chinese District on the West Side and the Japanese District on the East Side. These two districts are in the National Register of Historic Places (National Park Service - Isleton Chinese and Japanese Commercial Districts). In the 1930s-1960s, Filipinos made their home in Isleton working the farmlands. According to the 2010 Census, the population is 804 residents that reside in the beautiful historic town.
