Actually, if mhurron is referring to what I think they are, then it can be fairly global. Think fish migration and spawning, such as with Salmon. Global Salmon population is very susceptible to being disrupted by blocking rivers. That said, I believe there are modern ways to address this problem.

Poorly built dams can damage the environment. Except you know, its 2016 and we've figured out how to preserve the environment while providing clean energy now.
