I don't know. It was a thing a few years ago, I believe I learned about it in the documentary Dam Nation (but I might be mistaken). Google no longer works for me to find things again that I vaguely remember. What I do remember was that they had taken out multiple smaller dams on a river, and if memory serves me right, a group had bought them for a reasonably low amount as the previous owners had no more use for them. Most of what I found with a quick search from what I remembered were public/private partnerships to remove obsolete dams (Riverkeeper seems to be a larger player).
