There are systems to allow salmon to go over dams. From ladders to cannons.

I hope they are right about this dam not needed for flood prevention. Spain just lost hundreds of people and suffered billions in damages because these kinds of policies.

Getting fish ladders to work where they exist, or built where they are lacking, is not an easy feat either.

And the dam removals in Spain have nothing to do with receiving 770 mm of water in one single day. None of the removed dams would have protected an area that was planned to get flooded when the works of the 1960s were done.

		There was a project to add flood prevention dams in the area but it was blocked for 20 years by the party in power. And it was from their own party's campaign promise. Also, the cleanup of existing dams and rivers was blocked due to environmental reasons. And the EU government was backing all this. At least most of Valencia was spared due to works made over 50 years ago. I don't believe the mainstream whitewashing of authorities. Administration openly against dams and waterworks, no alerts due to malfunctioning radars, terrible coordination, and lack of appropriate response.
