Stillwater trip

Yesterday, 3rd April, i decided to have a day at a stillwater fishery, the chosen venue being Hawkridge reservoir, near Spaxton.
The day started rather dull and grey with a slight breeze blowing from left to right.
Having duly paid my money, tackled up, it would appear that i was the only person on the reservoir! i had the whole place to myself, no looking for somewhere to fish from, just wherever i wanted.
I started fishing from just to the right of the boat pontoon, which was just in front of the lodge, second cast, tug? nothing, forth cast, another tug, nothing! a few casts later a fish on, a few seconds later, fish off!! then it happened again, check hook, that was ok, at last fish on, and successfully landed,  it then went quiet,no tugs, knocks, nothing, time to change the fly, remove black gold head, and replace with orange gold head.
I now moved to fish from the boat pontoon, thus giving me a bit more distance, to where fish were moving, bingo! first cast a fish! then all went slack, i hate losing fish! the air turned blue! 
However, after that the fish all managed to stay on and i caught my allowance.
Just as i was landing my last fish, another angler arrived, the first person i had seen since arriving at the fishery.
Tight lines to you all.
