I assume that all border wall versions will cut off access to the river to everybody on this side. Has there been any discussion about rerouting the river. Not kidding about that, losing access to the river is kind of a big deal.
“any discussion about rerouting the river”?
Since the river is the International boundary, it is governed by a ratified treaty.
To accommodate water needs for ranchers, water can be piped to other side of the fence. For farmland, homes or businesses, or even recreational use, gates can be installed with keypad access.
