The fish hatchery was the site of Looking Glass's village which was attacked on July 1, 1877 by U.S. army soldiers. Looking Glass subsequently joined Chief Joseph to become a leader in the Nez Perce War. A plaque describing the event and a nature trail on the site have been established by the Nez Perce.
