So the waterfall has to get the water from somewhere right? This can be from ice, a river, a lake, etc. Niagara Falls gets its water from a few of the Great Lakes. So now the question is why doesn’t the source run out. Well either the source is infinitely large (impossible) or somehow it gets refilled. The refill is done through the water cycle. That’s right; Evaporation, Condensation, Transportation, and Precipitation. The biggest replenishing action comes through rain. It is true that if the source does not get refilled fast enough, it and/or the waterfall will dry up
