Evaporation from reservoirs will increase; water storage in reservoirs will decrease. Under the current projections, according to Gutzler, the Rio Grande basin will see a 4 to 14 percent reduction in the amount of water in the Rio Grande and its tributaries in the 2030s, and an 8 to 29 percent reduction by the 2080s.

Climate Change Impacts on Agriculture in the Rio Grande River Basin T he Rio Grande is an essential freshwater source for over 13 million people living in north-ern Mexico and the southwest-ern U.S. (USCB 2013, CONAPO 2013). At 1,896 mi (3,051 km) long, the Rio Grande is the fifth longest river in North America and the twentieth longest river in
The Rio Grande. The Rio Grande River flows along the U.S. (Texas)-Mexico border for nearly 1,248 miles (2,008 km) including meanders. Although snowmelt from the San Juan Mountains of Colorado (Fig. 7) is a major source of water for the Rio Grande, runoff from northern Mexico also contributes to its flow. As in all arid to semiarid regions, the ...
At times the Rio Grande carried relatively more water (discharge) and less sediment; at other times, it carried less discharge and more sediment. Over geologic time, changes in the balance of discharge versus sediment load filled rift basins and sculpted the landscape.
The Rio Grande: A troubled river.

At least seven species of fish have now disappeared from the Rio Grande in the Big Bend area, including the American eel, the sturgeon and the Rio Grande silvery minnow. Also, at least five native mussels may be gone, since only the dead shells of three species have been found in recent years.
Because of the Rio Grande’s importance to the overall environmental health of the Big Bend region, Big Bend National Park cooperates with the U.S. Geologic Survey (USGS) and other agencies to monitor the river’s condition and the quality of its water.
And the Big Bend slider (a species of turtle) may soon disappear, since it is adapted only to swift water conditions. Along with its reduced and regulated flow, the river frequently contains high levels of salts and bacteria, as well as agricultural and industrial chemicals. Such contamination affects a wide variety of species.
A slight rise in May 2002 correlated with a drop in dissolved oxygen that was severe enough to kill fish near Hot Springs. The park’s monitoring activities have contributed to a program called the National Stream Quality Accounting Network (NASQAN). Sponsored by the USGS, this program eventually will provide important clues for determining ...
This in turn may be the first step in restoring at least some of the river’s natural vitality and ecological importance. Without many dramatic changes , it seems unlikely that the “big river in a stone box” will ever fully regain its former, natural role in the story of America’s Southwest.
Population growth has also been a factor, particularly in Mexico, where the population has nearly doubled since 2005, and nearly 6 million people depend on the Rio Grande River and related groundwater basins for drinking water. The U.S.-Mexico Treaty of 1848 established the international boundary, modified slightly by later "Conventions.".
and Mexico is regulated by Treaty (see below). Rio Grande River water is in demand because of the intense agriculture in New Mexico-Texas (Fig. 8) as well as in northern Mexico. This water supply deficit has been exacerbated by prolonged drought in the southwest.
Releases from Elephant Butte Reservoir control streamflow to El Paso. At American Dam, much of the flow in the Rio Grande is diverted for irrigation and municipal uses in Texas and Mexico.
In all, there are 15 dams on the Rio Grande River, many of them in New Mexico. Flows are significant until Elephant Butte Reservoir in New Mexico. El Paso, TX is 125 river miles downstream of Elephant Butte Reservoir and just upstream of the American Dam.
The Treaty of 1944 between the two countries partitioned water from the Rio Grande River along the Texas-Mexico Border (as well as stipulating Colorado River flows to Mexico, see above), modified slightly by a 1970 Treaty, and authorized both countries to construct, operate, and maintain dams on the main channel of the Rio Grande.
The Pecos River, a major U.S. tributary, joins the Rio Grande another 300 miles or so downriver near Langtry, TX (Fig. 7); the Pecos flow is also controlled by a dam upstream from its confluence with the Rio Grande. Further downriver, the flows in the Rio Grande River decrease significantly as the result of withdrawal for agricultural ...
The Rio Grande mainly extended downstream over time, rather than upstream, reaching the Gulf of Mexico between 1,600,000 and 600,000 years ago.
The river begins in the San Juan Mountains of Colorado and flows south through the center of New Mexico. South of El Paso, Texas, the Rio Grande coincides with the boundary between the United States and Mexico. It enters the Gulf of Mexico at Brownsville, where it has formed a delta. d.
Major tributaries of the Rio Grande, such as the Rio Chama, originate outside of the Rio Grande rift and add water to the river. Other rifts in the world commonly contain large river systems (e.g., White Nile, Rhine, lower Mississippi) and provide important sources of water, oil, and natural gas.
We begin the story of the Rio Grande at about 28 million years ago (abbreviated Ma), when its namesake rift was just starting to form in northern New Mexico. During and before this time, an episode of extensive volcanic activity left much of New Mexico covered in lava flows, volcanic ash, and volcanic sediment.
This view of the upper Rio Grande gorge looks north past Ute Mountain (the cone-shaped mountain beyond the snow) and into southern Colorado. The San Luis Hills, left and just beyond Ute Mountain, formed a topographic barrier to ancient Lake Alamosa.
For most of the past 2.6 million years, streams draining high peaks around the northern San Luis Basin were not connected with the Rio Grande, but rather ended in a closed basin containing Lake Alamosa, which slowly filled in with sediment.
For a number of reasons, including sediment break- down and addition of water from tributaries, rivers commonly develop a concave-up, “graded” profile in which erosion and deposition tend to smooth out major irregularities.
The Rio Bravo basin has about 471,900 Km2. Approximately half of the basin belongs to the United States, and the other half to Mexico. The Rio Bravo is extremely important for both the United States and Mexico.
Bravo River. Today its length ranges between 3051 and 3060 km, depending on the course changes of the river. Also known as the Rio Grande on the other side of the border, it is considered to be the fifth longest river in North America, and the 20th longest river in the world.

The Importance of the Rio Bravo Is in particular the international boundary between the United States of America and the Mexican Republic. The Rio Bravo forms the border between the state of Texas (USA) and Mexico. According to the International Boundary and Water Commission, its total length at the end of the 1980s was 3,089 km.
Here are some of the most relevant aspects around this topic: - According to the Treaty of Guadalupe Hidalgo, from 1848 the Rio Bravo constitutes the basis for the establishment of the international boundary between Mexico and the United States.
The Rio Grande Valley has extremely fertile soils, and today there are approximately 800,000 hectares of cotton, citrus and vegetable crops in general. In addition, the Rio Bravo also favors the practice of livestock in the area. - From the economic point of view, although the Rio Bravo is only navigable for some small vessels, ...
At nearly 1,900 miles, the Rio Grande is runner-up only to the combined Missouri-Mississippi system in length within the continental U.S. Or it would be, if it still flowed the length of its channel.
Map of the Rio Grande River. Will Rogers once described the Rio Grande as “the only river I know of that is in need of irrigating,” a prescient observation considering how fragmented this fabled river has become.
The box canyons of the Rio Grande del Norte National Monument, dedicated in 2013, offer dramatic wilderness and important bird sanctuary surrounding some of the finest whitewater in the West for skilled paddlers, establishing an outdoor recreational mecca that extends downstream along 74 miles of Wild & Scenic river.
Yet segments of the Rio Grande remain among the most spectacular in America, including two design ated National Wild & Scenic River stretches, a pair of National Monuments, and a National Park. After wending its way through some of the top trout waters in southern Colorado, the Rio Grande tumbles into a cavity of sheer-walled canyons carved from ...
