Little video of a stunning place.
Enjoy.

Nice, but why dont you post it in "Works" section

Hello there Drone chappy. Good day and thank you for posting this cool aerial video that you have filmed. Great flying and have a nice day. .

Lovely views. I'm intrigued by the control tower for the reservoir with its open window holes through which the water must flow as the level rises.

Beautiful. At 0:39 there looks to be an upward moving inflow, do you know if that is a natural spring or a piped flow?

Beautiful footage.

The Foel Tower is effectively a complex valve, regulating the outflow from the Garreg Ddu Reservoir and others further up the valley; it houses a system of valves and cylinders which can be raised and lowered hydraulically to draw water off from the reservoir at various depths as required.
Here you go.

Quite different in style from this one at Fernilee Reservoir, near here

Beautiful footage.    What a great location for flying.

I believe it is piped flow ,they were doing a lot of work and pumping water from one dam to another.

Very nice to see!
