You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 3.231.0.0/16 has been blocked (disabled) by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 06:15, 30 September 2026.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

The '''Boundary Treaty of 1970''' is a [[treaty]] between the [[United States]] and [[Mexico]] that settled all outstanding [[Rio Grande border disputes|boundary dispute]]s and uncertainties related to the [[Rio Grande|Rio Grande (Río Bravo del Norte)]] border between them. 

The most significant dispute remaining after the [[Chamizal dispute|Chamizal Settlement]] in 1963 involved the location of the boundary in the area of [[Presidio, Texas]], and [[Ojinaga|Ojinaga, Chihuahua]]. The river channel was relocated to approximate conditions existing prior to the dispute that arose from changes in the course of the river in 1907. The [[International Boundary and Water Commission]] was charged with its implementation. The ''[[American-Mexican Treaty Act]]'' of October 25, 1972 authorized participation by the United States IBWC section.<ref>[https://www.law.cornell.edu/uscode/text/22/277d-34 22 U.S. Code § 277d–34 - American-Mexican Boundary Treaty, authorization for carrying out treaty provisions; investigations; land acquisition, purposes; damages, repair or compensation]</ref> The project commenced in 1975 and completed in 1977.<ref>((cite journal|author=Robert J. McCarthy|title=Executive Authority, Adaptive Treaty Interpretation, and the International Boundary and Water Commission|publisher=U.S.-Mexico, 14-2 U. Denv. Water L.|date=2011|ssrn=1839903))</ref>

==Provisions==
The river was relocated in two reaches by the construction of a new ((convert|4.7|miles|km|adj=on)) channel in one reach and ((convert|3.6|miles|km)) in the other. The relocated channel was aligned in the reach above Presidio-Ojinaga so as to transfer from north to the south side of the river ((convert|1606.19|acre|ha)) and in the second reach downstream from the two cities so as to transfer from the south to the north side a net area of ((convert|252|acre|ha)). It is an earth channel with dimensions patterned after the natural channel. The United States acquired ((convert|1969.22|acre|ha)) of American agricultural land that was used for the transfer of lands to Mexico and for half of the river relocation.

Also, the channel of the Rio Grande in the [[Hidalgo, Texas|Hidalgo]]–[[Reynosa]] area was relocated to transfer from Mexico to the United States ((convert|481.68|acre|ha)) by constructing a new ((convert|1.6|miles|km|adj=on)) earth channel. This transfer was made in exchange for the transfer from the United States to Mexico of two tracts of land, the [[Horcón Tract]], after 1906 located south of the Rio Grande, and [[Beaver Island (Rio Grande)|Beaver Island]] (La Isla de Morteritos), located in the river south of [[Roma, Texas]], comprising ((convert|481.68|acre|ha)) in total. This provision transferred to Mexico the portion of the town of [[Río Rico, Tamaulipas]], located within the Horcón Tract.

The cost of the two relocations was shared equally by the two governments, with the United States performing the greater part of the work required in the Presidio-Ojinaga area, and Mexico performing the work required in the Hidalgo-Reynosa area and a small part of the work required in the Presidio-Ojinaga area.
