Rio Grande border disputes

• The Country Club Dispute was a dispute between Texas and New Mexico. The U.S. Supreme Court resolved this dispute in 1927.
• The Chamizal dispute was a border conflict over a parcel of land between El Paso, Texas, and Ciudad Juárez, Chihuahua. The dispute was resolved by Chamizal settlement in 1963.
• The Ojinaga Cut was a disputed parcel of land between Presidio, Texas, and Ojinaga, Chihuahua. The dispute was resolved by the Boundary Treaty of 1970.
• The Horcón Tract was a parcel of land surrounded by an oxbow bend of the Rio Grande, including the village of Rio Rico, Texas, that inadvertently defaulted to Mexican administration with the passage of time after an irrigation company in 1906 dug an unapproved cut across the oxbow to change the course of the river. The issue, which was not technically a dispute as both sides were in agreement about its legal status upon its discovery, was resolved by the 1970 treaty which ceded the land to Mexico, but the official handover did not take place until 1977.
