Formed by damming the river Têt, this is one of the main reservoirs serving Perpignan and the Roussillon plain. It can hold 25 million cubic metres of water, but after a long hot summer it is quite low. I think in Spring the place where I was taking the photo from would be about 5 metres below the surface. According to an information panel, it is currently supplying 6 cubic metres per second, and if you can't visualise that, then think of a 20 tonne road tanker being filled in 3 seconds.
