But then again anadromous fish migration, as it currently exists, or what remains of it in the Pacific Northwest, is almost an entirely manufactured and deeply anthropologically influenced system; a particularly costly one.
Steps like these seem a interesting turn or implication given the two choices at hand: remove the dam infrastructure or upgrade the infrastructure for fish passage. Dam removal attempts to roll back the human influence on the system in a whole-scale sort of way, significantly altering the course of the last 100 years or so. Upgrading tends to increase the hybridization between species (as I think you are highlighting) via technology in places where the infrastructure is deemed as necessary. Either trajectory has a long cascade of repercussions that are qualitatively very different.
