Hydroelectric dams aren't all sunshine and roses.

> “The river was transformed from being a thriving producer of millions of ﬁsh such as shad, herring, striped bass, Atlantic salmon, sturgeon and alewives and supporting a wide cornucopia of other species ranging from otters to eagles — into a wastewater drainage system,” Jeff Crane, a dean of the College of Arts and Sciences at Saint Martin’s University, wrote in a paper published in 2009.

Sounds like something else is going on. There shouldn't be much difference between the amount of water flowing into and out of a hydro dam.

It's not about the water flow, it's that there's a physical barrier that blocks migrating fish from going between the river and the bays/estuaries/ocean.

Most fish species don't migrate.

I mean, that's true, but also every fish species listed in the above quote does, and were severely negatively impacted by the dam. They in turn feed a large amount of other wildlife.

I see. My mistake, I thought only salmon (from your list) migrated.
