The S-Bends on the River Tummel a year ago, when the dam broke originally and repairs meant that the water level was higher than usual. From my vantage point a pile of rocks in river centre, the main chute was a foam pile between a big pourover on river left and a small, submerged rock that isn't so obvious here. The water level was slightly higher in this spot the day we paddled it. The next day, when the kayak club came through here, they got to spend a few hours recovering a pinned boat from that slightly less submerged rock.
