Gestalgar
This is where river water is diverted into the hydro-electric plant at Gestalgar.  I was standing on a bridge over the water to take this when I noticed a sign saying that this was very dangerous as the water was subject to large, unexpected fluctuations in level.  Time to exit, stage left!
