What natural behavior of the Rio Grande made it necessary for the US and Mexico to legally fix its historical channel as their shared border?
Answer
The river's channel naturally shifts over time
Because sediment and flooding cause the Rio Grande to naturally move its course, a treaty was needed to keep the legal border fixed at the river's historical path rather than its ever-changing current one.
💡 Did you know?
The Río Grande between USA and Mexico shifts constantly. A 1963 treaty requires both nations to maintain its exact historical channel, even as the river moves.
