Do you have a source hydro turbines “turning fish in to mulch”? I’ve been around lots of hydro projects and the main hazards for fish seemed to be either dewatering of habitat due to turbines reducing flows too quickly or I heard it is bad for them if the dam uses the spill way and makes the water all aerated
I was being a bit glib there, I just meant that it was bad for the fish. My understanding is the average mortality rate for fish passing through a dam is 1 in 5. [1]
