Hi Ped, at the moment the rivers are high, due to the large amount of rain lately. Normally at the moment, upstream dry works well, a parachute type fly, para adams, klinks, and olive patterns will usually get a take.
The late evening you may find success with a sedge pattern, CDC or deerhair.
If the water is coloured try a nymph, upstream for best results, but if you struggle with that, across and down should do as well.
A gold head is often reliable, no fixed rules at the moment, as it's like February here rather than August.
Things can only improve though, can't they ?
