It depends where they are moving the water to. When the story first broke
(no pun intended) I looked at the area on Google maps. I doubt they are
moving the water to below the damn- based on the area and what I d heard
on the news. They seem to be diverting water which normally flows into the
lake behind the damn and pumping it out into rivers in the area.

Siphons require a €˜drop or €˜head which, especially as the level drops,
probably wont exist on the high side of the damn.
