Isleton was founded 1874 by Josiah Poole. After having the town platted, he constructed a wharf on the Sacramento River, and a booming town soon followed. However, Isleton was flooded in 1878 and 1881, causing Poole financial difficulties and leading him to move out. The town also flooded in 1890, 1907, and 1972. As agriculture in the surrounding area developed, three canneries opened up in Isleton and other delta towns. The cannery workforce was over 90 percent Asian.
