Beaver dams are different. They leak, let fish through, and disappear every few years. Details matter.

- redandblack 3y agoThis is the key and overlooked part of it all. Plus they can move upstream or downstream as situations dictate.
- bmitc 3y agoGood point. It's almost like the word system in ecosystem is important. Haha. Your comment makes me want to learn more about beavers. I'm interested but don't know much.
- mcpackieh 3y agoI think most dams (small low head dams, often abandoned) have those same properties.
- ajuc 3y ago3 years vs 30 years. And you usually regulate the river around the dam so it can't meander, beaver dams make the river meander around them. So after 30 years you maybe return to status quo with a small, abandoned human dam. In that time you would have 10 different riverbed changes with beavers and all that area is now marsh.
