Believe it or not, I have begun to see more and more pedal yaks on the middle Brazos lately. I personally would not use mine down there, but I have both paddle and pedal, so I have options. The water release issue not withstanding, the middle Brazos has more deep pools than the upper, so there's that. Also, with the recent releases a lot of the grass/moss has been washed away (although it will always has some grass you will have to deal with). But as mentioned before here, you have to be willing to ride the release down to Dicks should they start generating on you (or hard slog it back to the dam).
