I have caught a lot of small browns in this stream, and a few good sized ones, as well. The reason for the the difficulty is that the Elbow below the dam is a very technical stream. It requires very long, light leaders (I usually go with 6X) and a stealthy approach. These are small stream Browns in relatively shallow water, and as such, they are super-spooky. But I find that using small nymphs and dries in the summer, and some larger streamers in the fall can get results. Also remember that the river requires a lot of patience to fish, as the trout can be very difficult some days.
