Russell,
Don't be disheartened mate. Loads of good info and help on here. Everyone on here will soon will get you catching. When I first started my, catch rate was low and I blanked a lot. Once you become more confident in your ability you will improve.
My advice is be methodical, fan cast at short range then increase the range gradually and fan cast again. Vary the depth by counting to 10 before retreiving then 20 etc, etc. Vary the retrieve, mix it up, slow, fast, jerky, fig 8 etc. If no luck change fly and start again. If still nothing move around and repeat.
As mentioned ask others, in my experience people are really helpful and some have even given me flies to help. I do the same when I am catching and others ask me for help. It's a great feeling to help others.
Ask in the lodge, check the returns book. Local info all helps. Most owners, managers want you to catch fish so you come back for more.
Have a look at this link.
Hywel Morgan On Fishing - Episode 1 | Horse and Country TV
Its a series of 12 programmes that I think were on Sky originally with Hywel Morgan presenting. Each one is about half an hour long and covers loads of good stuff. Scroll down the page and you will see the other episodes. I watch them on my laptop on Sat nights with headphones on when my wife is watching cack X-factor type programmes!! I've learnt loads watching them.
Hope this helps, keep going and let us all know how you get on.
Tight lines!
Nick.
