Rio Grande The Rio Grande (/ˈriːoʊ ˈɡrænd/ or /ˈriːoʊ ˈɡrɑːndeɪ/;[5][6][7] Spanish: Río Bravo del Norte, pronounced [ˈri.o ˈβɾaβo ðel ˈnorte] or simply Río Bravo) is one of the principal rivers in the southwest United States and northern Mexico (the other being the Colorado River). The Rio Grande begins in south-central Colorado in the United States and flows to the Gulf of Mexico.[8] Along the way, it forms part of the Mexico–United States border. According to the International Boundary and Water Commission, its total length was 1,896 miles (3,051 km) in the late 1980s, though course shifts occasionally result in length changes. Depending on how it is measured, the Rio Grande is either the fourth- or fifth-longest river system in North America.[1]
Pecos River The Pecos River is a river that originates in eastern New Mexico and flows into Texas, emptying into the Rio Grande. Its headwaters are on the eastern slope of the Sangre de Cristo mountain range in Mora County north of Pecos, NM, at an elevation of over 12,000 feet (3,700 m) feet.[4] The river flows for 926 miles (1,490 km) before reaching the Rio Grande near Del Rio. Its drainage basin encompasses about 44,300 square miles (115,000 km2).[2]
