Husum Falls, White Salmon River, Washington
Did the 08/09 winter logjam in the waterfall affect the Hydraulic?
This question has been fired around Constantly in the '09 season. Husum Falls is retentive and Fifos from far and wide are getting stuffed and surfed. I have been doing some research... looking at photos of the falls from this year and from previous years. I have even heard talk that the Flake (boof-rock) has moved forward as much as 3 feet (!).
For Anyone not familiar with our goofy boater-lingo. The Flake is essentially a "ski-jump" set in the top half of the falls (or anywhere really). When one paddles their kayak over the appropriate line on a falls containing said flake, The Hydraulic at the base of the waterfall (This is a very turbulent recirculating hole) can be avoided as the kayaker in a sense "jumps" over it.
So, back to business. Husum is a waterfall. lets break it down...water = Incredibly powerful and unforgiving force of nature. Fall - ouch. Lets give credit where credit is due. A waterfall is not splash mountain at Magic Kingdom. Ask any good boater how they decide to run a big drop like Big Brother, in the upper reaches of the White Salmon. They scout and then decide yes or no. Not based on weather or not they did it last week, or their buddies say go for it. They decide based on how they feel about the drop at that moment. How are you interacting with your boat, the water, what did you have for lunch, do you have a wicked rash between your toes that itches and might prove to be a minor distraction. ummm.... oh yeah, my point:
Look at the waterfall, can you hit the line you want to hit? If you don't can you work out of the hole? Hold your breath (haha)? Do you even know what a good line is? if not maybe watch some others who know run the falls and then decide? do you know what a line is? If not ask your raft guide =o).
Below I have posted a few pictures of husum falls (Lets see if the Flake has moved three feet)
Above: The Author runs the Flake at Husum July, 2009
Below: A similar angle taken of the falls quite some time ago at a similar water level ~2.5 ft on the Stick at Husum. Flake looks about the same to me. Also note that I am looking at the top of the wild spray coming off the rock in the arc (not the throw of the spray itself) as the angle is not exactly the same, the spray will look different.
Below: Steve Stuckmeyer runs a line to the left of the flake at around 3 ft. The Red Line displays the line off the flake rock at this angle. From Americanwhitewater.org

Below: Another Angle of Husum Falls Showing a clean line off the boof rock. Note the approximate area where the red X is and the line ends, Not even close to the nasty looking U-shaped Hole at the base of this one.

I cannot speak to the retentiveness of the hole. Is it possible that some rocks have moved around at the bottom? yes, it is a river. The very nature of a hole is to be retentive. It is afterall really just a wave and waves as we all know, surf...sometimes whether you like it or not. I have a friend who ran into a rock pile on the Hood and had them move around under his boat. Cool!
If you are a Kayaker, hit the line. If you are a rafter, have some faith in your guide and don't try to breathe water. Don't assume that because it has been done before that you can do it again. I also found a good youtube video of a clean line and a dirty line off the falls.

Whatever you do, Be safe on the river and for goodness sakes lets leave the Hydrology and bathymetry to the experts.
