Geograph - photograph every grid square

This rapid starts with a wide shallow area (there are stepping stones visible on aerial photos although these are not seen by canoeists if the river is at an adequate level). Paddlers then try to get river left to the deeper channel, whilst avoiding overhanging trees on the left bank, and the central rock at the bottom. The photo shows a depressingly low level (the River Swale rises and falls quickly and is hard to catch at a good level). With a bit more water, a playwave forms at the bottom of the rapid, but then at high levels washes out completely.
