Dams don't 'dry up' rivers - they control them. The lake created doesn't have infinite capacity. Once filled, the flow downstream resumes normal levels. Just doesn't have floods like it used to.
- readthenotes1 4y agoWhere I live, we then drain those lakes regularly for the water of our cities so the water available down stream is greatly reduced except in tons of flood in which case it is unusually high.

- rhodorhoades 4y agoThis is untrue. You aren’t thinking about the effects of sediment, usage, and erosion. When you build a dam and allow the riverbeds to dry, it changes the entire water table of the region.

- JoeAltmaier 4y agoThey don't dry; they resume as normal once the dam is complete. I don't understand that nobody can see this. The lake can't hold all the water to inifinity. Once it's full, the outflow becomes normal. Except now you can regulate it.
