You have to have something to keep the water contained between the two.

But those aren't dams. Dams are something that stops the flow of water. And it's this stoppage that causes the environmental problems.

Reservoir walls might look like dams, but they're not dams.

  • The main enviromental complaint is in flooding huge areas of land, which is the case with both dams and reservoir walls.
