Following the Great Depression, the Central Valley Project was established to provide a stable sources of water for irrigation. The Project plans encompassed thirty-five counties in an area about 500 miles long to 60 miles wide and was the largest water project to date. By this time, the landscape makes a reverse from islands of irrigated farmland to mostly irrigated farmlands, with large island blocks of natural lands.
