Crikey! I assume it is Arboleas? Incredible to think one of the Old Fellas up here (84 at at the time he told me in 2009) learnt to swim there when he was a child while his Father fished. I doubt the water would have run as fast as this appears to be.
In the valley here passing Purchena, Olula etc, it has been running with water all year. No idea where it is coming from though...
