Sounds like watered down birth control
Was kind of my first thought as well.
Maybe you could add a fresh water source by their salt on both sides of river to just try and reduce their water consumption from the river. Be interesting to ask neighbors if they have issues as well.
I do have the salt and mineral barrel close to a tire tank that's away from the creek.
