A quick note. The level was 1.62. This is the highest level Bonney would recommend me running the river. 1.62 is perfect for the gorge. Scary if higher, slower but more technical if lower. There is a video on YouTube which is good. BCC on the east Lyn nov 2011. I would highly recommend ABC Kayak.
Another quick thought. Paddlers at the club are capable of the upper section from Brendon to Watersmeet and I would be comfortable leading a group at that level. I would recommend walking the gorge unless with a good team or guide.
