The waterfall never completely dries up, but in dry times it does slow to a trickle.
However, the pool’s water level stays pretty constant, even during periods of drought.
The pool is located about 37 km west of Austin, Texas off Highway 71.
Since the 1960s, Hamilton Pool has been a favorite summer swimming spot for Austin visitors and residents.
