While putting together the press release and mass mailing for the launching of this blog, we found some pretty interesting facts about Celilo Falls. Perhaps the most impressive to us was this little gem: during high water, almost 450 million gallons of water flowed over the falls every minute! To put that in context, the average volume of water that flows over Niagara Falls is 70 million gallons—about one seventh of the volume of Celilo Falls! Of course, that was before hydropower development, something Niagara Falls didn’t entirely escape either. Hydropower diversions above the falls take 1/2 of the water and only about 35 million gallons per minute actually pass over the falls.
Spanning the Canadian/American border, Niagara Falls is neither the world's tallest nor broadest cascade, but it is among the most impressive and currently the single most powerful.
