Ayer's Rock
Uluru was not found by anyone named Ayer. Explorer William Gosse, of the South Australian Survey Department, is believed to have been the first European explorer to see Ayers Rock. Gosse discovered the rock (now known by its native name of Uluru) by accident during an expedition through Australia's interior. Known to the indigenous Australians as Uluru, the rock was named Ayers Rock after Sir Henry Ayers, Premier of South Australia at the time.
If by Mount Ayer you mean Ayers Rock, it does not influence rivers. Even when the rains come and water streams down the Rock, no rivers are formed. There are water pools around the base of the rock, but no rivers nearby.
