Where do we get fresh water from?

There are different types of rivers. Rivers have 3 main stages. In the first stage, young rivers carve down towards v-shaped valleys and pick up rocky debris along the way. Waterfalls are common features of rivers. 
In the second stage, rivers deposit materials making a river channel. 
In the final stage, rivers flow sluggishly and meanders become more pronounced. 
Where does the water for a river come from?

It comes from snow, steam from home cooking, rain and factories.
