Yes, they call those fish ladders!
They are used to allow the fish to get to their spawning beds. However, the smolts (juveniles salmon) still live in the streams downstream of their spawning beds and require temperature and sediment to be "natural".
If the proposal were to focus on "Anadromous Fish Protection", I think including a clause recommending fish ladders and encouraging national fisheries agencies in sharing the technical designs related to these and other fish passage structures would be a neat idea to promote.
It seems like there are probably enough different fish options that the resolution could just focus on that, without getting into drinking water issues.
