nope, I see this as a negative thing. They only destroyed the dam because it was more cost effective for them than installing a fish ladder to allow the fish to migrate past the dam.
that hydro dam alone would have generated more low carbon electricity a year than all the PV installed in the UK since March, and has been generating that electricity for most of the last century.
it all seems pretty nuts to me, but hey at least the canoeists and fishermen are happy.... shame about the mountains having their tops blown off and the valleys filled with the waste to strip mine the coal that will be burned instead, which is the real truth of the matter.
