Bristol Frome returns to relatively normal level but where are the fish?

Fished Bristol Frome tonight. Caught three average Brownies on the dry. River lower than Chew but still high for this time of year. Again fish are just not around. A few small shoals of Chub and the odd Brownie are the only signs of life. Chub just too easily spooked but all three of the Brownies I saw rising readily took a small Klink. The Frome is quite heavily segregated by weirs and riffles so I think it is going to be some time before the stretches I fish start to return to the form they were in earlier in the year- perhaps I need to head downstream and fish with the dogs!.
