Don Smith (left) poses for a photo alongside his mother, Eva Harris, and stepfather, Harold Harris, in the diversion tunnel built during construction of the Dworshak Dam on the North Fork of the Clearwater River near Orofino. The tunnel served to divert the river around the dam site so work on the dam itself could commence. Smith reports this photo was taken on the last day members of the public were allowed to tour the diversion tunnel, probably in the late-1960s, and the Kamiah family made sure to record their visit to the site. A couple of days later, Smith says, the tunnel was flooded by the waters of the now-diverted river and the foundation work began on Dworshak Dam. The dam was opened in 1973.
