I calculated the kinetic energy of the falls using the figures provided in the text and the formula
Mass is nine cubic miles per hour; Velocity is 45 miles per hour (although a 65 mile per hour figure is also given, making this a conservative calculation.
Nine cubic miles is 37.5 cubic km. Assuming one cubic m of water weighs 1000 kilograms, that's 3.75x1013 kg
Divide by 3600 to get kg per second: 1.04x1010
45 miles per hour is approximately 20 metres per second.
0.5 x 1.04x1010 x (20x20)
= 2.08x1012 Joules
As this figure is calculated per second, it is identical to 2.08x1012 Watts, ie, 2.08 Terawatts.
World electricity consumption in 2001: 1.7 TW World electricity consumption in 2005: 2.0 TW

I was wondering if Frenchman Coulee or Potholes Coulee would also be considered dried waterfalls. How do they compare in size? — Preceding unsigned comment added by 71.37.50.136 ( talk • contribs) 05:21, 27 June 2007 (UTC)
Yes it is a great picture, but that doesn't mean it gets to ignore the guidelines for image placement in articles. The pages on Mt Rainier, Mt Adams, Glacier Peak all cover majestic natural features, and all follow image placement guidelines.-- Kev min § 23:15, 13 May 2013 (UTC)
