Just FYI for anyone who wants to paddle the Cascade River at some point, you have a new gauge. It is located under the bridge at the Cascade River Park, at the last decent rapid. It's a real gauge and measures in meters/centimeters. Why metric you ask?... because the English measurement system is stupid and gauge height is pretty much an arbitrary scale anyway, so might as well use something easy. I was able to get a bunch of gauge readings on my camera over a wide range of flows with this last rain event. I checked the date/time stamp on the photos and correlated those to the USGS flow (CFS) reading. I have it pretty well correlated, but will be fine tuning my data as I get more. If you happen to float by the gauge, please snap a picture of it and send me a message with date, time, and height in cm.
My preliminary correlation equation is:

CFS = 0.0876X^2 + 15.7X + 195

Just plug in the gauge reading (cm) for X and you will know what the flow is.

Enjoy,
Eli

So apparently the last flood ripped the gauge out of the concrete wall it was attached to. It was anchored with four 3/8" concrete anchors, two of which were ripped out of the wall, and two of them must have ripped out the side of the 2x8 the gauge was attached to because they are still in the wall, but there is no gauge any more

Looking at some of the log jams last weekend, I guess it probably got hit with an old growth or something, because it took a hell of a lot of force to take that thing out. Oh well. Maybe I will try again at some point if I can find a good place to put it that a tree won't destroy it

Please disregard my previous post

I've been doing some work installing wood stuff to concrete lately and the spec is for us to use screws instead of pins. The architect says screws have more bite and shear strength. He's also spec'd out using some large washers along with it. Don't know what the shear rating is for half a log jam grazing by

During that big flood event when the sky hit 100K I was staying in a cabin on the NF Sky that we had rented. We were all mesmerized by the 50-60 freshly uprooted trees that were coming down the river every 10-20 sec. We had a couple nice people stop by and mention that the house usually doesn't flood but trees have taken out parts of the deck. I was skeptical thinking this flood wasn't going to be big enough but as it got about 15k over the 50k forecast and the power was out we decided to abandon ship and go get a hotel away from the river. The next day a big part of the deck was gone!!!Bummer about your gauge and hard work that sucks. How about making a nice stencil and spray painting it on when its super low this winter? I've thought about doing that on Deer Creek. On the Deer Creek take out bridge Mike Nash uses a piece of graffiti that seems to work pretty well.

Nash has sprayed on a proper gauge on Deer creek that is very nice.
The line will become apparent

I might try doing the spray paint thing and see how it goes. The concrete looks scoured after the last flood, so I doubt spray pain will last in that location. I probably just need to find a different spot for the gauge. Thanks for the tips. I will look around some more and see what I can come up with.
