Standing waves at 3,340 CFS

Selected for Google Maps and Google Earth

This is a ten second exposure showing the two or more LARGE standing waves created by the dam outfall at high release volumes. This is one of the rare times I have seen it OVER 3,000 cubic feet a second and it is most impressive. Often kayakers come and surf these big waves but not this night.

Thank you... took some post-work to make it look like a wave.

How do you measure the volume of water? Is it just an estimate based on length and height of wave, how do you measure speed of flow..... it's sad but I need to know these things!

Its not sad at all Kenny, perhaps a little burdensome on you (I speak from experience) I keep a mental list of all the things that I question throughout the day and love the wee hours around dawn when her-indoors is still asleep and I can go research all this crap!

Anyway, the reason I know this is that the gauge tells me so!

I even get automagic emails periodically if the water level is high - such is the life of a kayaking nerd!


Be good - David
