Towards the weir

The area of the river where it is most likely to see water voles is along a clear stretch from the footbridge up to the Dragons Teeth (a world war 2 defence barrier).  After that, the river becomes covered by trees and soon flows down a weir:

But looking closer shows signs of water voles. Notably burrows, not as many as upstream but still evident

It's also harder to see a water vole, I had to wait half an hour before one popped out:

I eventually saw three, all recorded on the water vole map (in blue):

Speaking to one of the regular dog walkers, water voles have been seen along the lower ock.
