Might these also be what we in western North Carolina call splash dams?
The ones here were constructed of logs to dam a river, making a pond.
Logs to be sent downstream to the mills were collected in these ponds.
Then, the dams were broken, and the backed up water helped to speed the
logs downstream.

Just a thought~
