Not all dams or dam removals are created equal.

It’s not just (or even mostly) the physical hinder to travel that is the problem with dams; the destruction of egg-laying habitat is huge.

Most of the dams that people are seriously talking about removing are inactive power generators (think Elwa) or never really generated power so much as facilitated shipping and irrigation (think Lower Snake River).
