The Sequim Irrigation Festival celebrates the work that D.R. "Crazy" Callen and his partners did to design and develop the Irrigation Ditches that brought water from the Dungeness River to the parched prairie. The first headgate on the Dungeness River was lifted on May 1, 1895. On May 1, 1896 the first celebration took place at Crazy Callen's farm. This was the start of a tradition that would become the oldest continuing festival in Washington state.
