Abstract: In 1986, a bolt of lightning hit the Upriver Hydro Project in Spokane, Washington and tripped the plant off line. The event triggered a series of events that included an undermining of one of the powerhouses when embankment structures were breached by the Spokane River. The mishap led to an $11 million fast-track rehab of the powerhouse. But the accident might not have happened had some fundamental flaws in the design of the freeboard been corrected.
