June, the water level is low, one can walk to the central of the river bed.
In fact, I had been to the island once. Back to summer 2015, I was here, the river was almost dry, and I easily went in to the island by the little path.
After about 10mn, I turned back. I did a little research afterwards. The island inhabited by 2 families, there are some agricuture aswell, but the farmers live outside the island.
