Thank you Vo Anh Tuan. It never occurred to me that it was a water beetle. As I have never seen anything like it in the water and being we were in such a dry environment. But on further reflection there is a section of the creek where it spreads out into a marshy area. This area is about a 5 minute walk from where we were.
