Flux, glad to see you around. Check out this video from last weekend. A group of 4 of us ran that route that you led sometime back. I've been having a blast exploring other areas around there.
Anyway, there had been 2 solid days of rain just before the ride and needless to say that 1st major river crossing was deep. I went through first and was expecting it to be deeper, but when my front fender was just about under water, I started to get a little worried. I had my camera on the handle bars on the way across, so it got soaked and didn't work for awhile, but we went back across that evening and I got video that time.
For comparison to the video, here is a normal height on that stream crossing.
