This is only happening because of other structures that require removal and are killing fish in large numbers with cavitation. I believe the objects doing the mass kill off are slated for removal.
This sensationalist headline isn’t helping anyone. :(
Exactly -- if you read the article they were killed by a dam that hadn't been removed yet. So it's like, no, the dam removal did not kill the salmon, the lack of dam removal did.
And yet, it happened. Doesn't speak well of project management.
