The 51-year-old said he stumbled across the strange scene by chance while driving through France.
He said: ‘I’d read a lot of things about Camargue but I’d never heard anything about this.
‘We were just on the way to the beach when we saw the striking lake.
‘It is absolutely stunning from far away but it’s even better when you get closer.
‘The salty crystals can be seen everywhere.
The natural phenomenon, which has seen salt levels turn water red, has had a breathtakingly beautiful – and eerie – effect on wildlife
Wild life in the lake in Southern France is bedecked with salt crystals which have gathered in clumps around stems of the plant life in the river
With every small branch encrusted with salt crystals and all flora and forna encased in white and set against the dark red background, the pictures could have been taken from the stills of a science fiction film.
Mr Dobson said: ‘Every small branch is covered with crystals and with the red water as a background it looks like something extra-terrestrial.
‘The strange thing is there are lakes on the left and on the right of this one and they are absolutely as you’d expect with normal water.
‘I was just overwhelmed with emotions the whole time I was there.
‘Despite my numerous travels, I have never seen anything like this before.’
