The Rio Grande in the United States or the Río Bravo in Mexico, also known as P’osoge in Tewa and Tó Ba’áadi in Navajo, is one of the principal rivers in the Southwestern United States and in northern Mexico. The length of the Rio Grande is 1,896 miles (3,051 km), making it the 4th longest river in the United States and in North America by main stem. It originates in south-central Colorado, in the United States, and flows to the Gulf of Mexico. The Rio Grande drainage basin (watershed) has an area of 182,200 square miles (472,000 km2); however, the endorheic basins that are adjacent to and within the greater drainage basin of the Rio Grande increase the total drainage-basin area to 336,000 square miles (870,000 km2).
Elephant Butte Reservoir is a reservoir on the southern part of the Rio Grande in the U.S. state of New Mexico, 5 miles (8.0 km) north of Truth or Consequences.

Elephant Butte Dam or Elephant Butte Dike, originally Engle Dam, is a concrete gravity dam on the Rio Grande near Truth or Consequences, New Mexico, in the United States. The dam impounds Elephant Butte Reservoir, which is used mainly for agriculture but also provides for recreation, hydroelectricity, and flood and sediment control. The construction of the dam has reduced the flow of the Rio Grande to a small stream for most of the year, with water being released only during the summer irrigation season or during times of exceptionally heavy snow melt.
Amistad Reservoir is a reservoir on the Rio Grande at its confluence with the Devils River 12 miles (19 km) northwest of Del Rio, Texas.

The reservoir was formed in 1969 by the construction of Amistad Dam. The dam and lake are managed jointly by the governments of the United States and Mexico through the International Boundary and Water Commission. The name of the dam and lake is the Spanish word for "friendship". The reservoir is also known as Lake Amistad.

With a total area of 121,590 square miles (314,900 km2), New Mexico is the fifth-largest state, after Alaska, Texas, California, and Montana. Its eastern border lies along 103°W longitude with the state of Oklahoma, and 2.2 miles west of 103°W longitude with Texas. On the southern border, Texas makes up the eastern two-thirds, while the Mexican states of Chihuahua and Sonora make up the western third, with Chihuahua making up about 90% of that. The western border with Arizona runs along the 109° 03'W longitude. The southwestern corner of the state is known as the Bootheel. The 37°N parallel forms the northern boundary with Colorado. The states of New Mexico, Colorado, Arizona, and Utah come together at the Four Corners in New Mexico's northwestern corner. Its surface water area is about 292 square miles (760 km2).
The Rio Grande Project is a United States Bureau of Reclamation irrigation, hydroelectricity, flood control, and interbasin water transfer project serving the upper Rio Grande basin in the southwestern United States. The project irrigates 193,000 acres (780 km2) along the river in the states of New Mexico and Texas. Approximately 60 percent of this land is in New Mexico. Some water is also allotted to Mexico to irrigate some 25,000 acres (100 km2) on the south side of the river. The project was authorized in 1905, but its final features were not implemented until the early 1950s.
