FYI: Ellsworth's first great disaster of the 20th century was the Great Flood of 1923. A spring freshet rushed over the dam and carried off the metal Union River Bridge, along with many buildings located along the river, such as the well-known Dirigo Theater, the Foundry and many wharves and warehouses. This event marked the end of Ellsworth's prominence as a shipping center. The present concrete bridge was finished in 1924.
