...in none of the coverage of the East River waterfalls have I seen anything about how this will affect the river ecosystem. Too many college geophysics classes have hammered it into my head that rivers really should run their course undisturbed (read: dams).

Yeah, yeah, I know it's the East River and it's not exactly teeming with wild salmon, but it really does seem odd that I haven't seen any news coverage that has brought this up.
