Description

Past the rookery and the concrete pipe the river flows against the right shore then abruptly turns left, drops down a riffle and dashes into the left shore where a number of trees and bushes hang over the water.  It is a common place for upsets and swims, but in 2012 a whole tree has fallen in and blocks most of the channel. It is now safest to avoid this channel completely.  Instead of following the main channel, stay far right up above and go down a very small right side channel.
