Pick your days!

Well, A couple of the upland lakes are fishing well but one must pick their days, easy I know for the retiree, not so for the working Man/Woman.
Light winds and some sun to encourage the hatch is perfect. The light winds can cause some frustration on these upland lakes due to their being surrounded by mountain cliffs etc causing constant change in wind direction and even a flat calm.
But patients is a virtue as they say and just take a break and wait until the breeze picks up between lulls and the fish respond.
That's the conditions sorted now to the fly, choice not so straight forward a frustrating business to say the least but so rewarding when you crack it.
I was out 2 weeks ago and amazing rise on the lake, 4 Hrs of it, I managed 7 fish eventually, all bar one around the pound mark, all taken on a tiny size18 emerging midge pattern. It was a tiny ginger midge pattern, No midges to be seen in the air so no clues, so I just went through the colours until Bingo, got it.
Cracked it you might think, I was up yesterday the 7th May a super rise on and lasted all of 6 Hrs. I started with my ginger midge pattern, Nothing, saw some Cog`s on the water, some attention but no hook ups, Saw some stone fly skittering on water and laying eggs, Nothing. Went through the colour scheme of midges once more, some sort of Bingo, caught 2 on an olive emerger but had to cast to something like 40 rises before contact, so not quite there. I took both fish for autopsy so to speak and found them stuffed with tiny 3 to 4mm dark olive midge pupa. I probably had come across a couple of trout with their eyes bigger than their bellies and they paid the price. Correct colour pattern but too big. So just shows what can change in a fortnight.
