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).
La Cienega is a census-designated place (CDP) in Santa Fe County, New Mexico, United States. It is part of the Santa Fe, New Mexico, metropolitan statistical area. The population was 3,007 at the 2000 census.
The Little Colorado River is a tributary of the Colorado River in the U.S. state of Arizona, providing the principal drainage from the Painted Desert region. Together with its major tributary, the Puerco River, it drains an area of about 26,500 square miles (69,000 km2) in eastern Arizona and western New Mexico. Although it stretches almost 340 miles (550 km), only the headwaters and the lowermost reaches flow year-round. Between St. Johns and Cameron, most of the river is a wide, braided wash, only containing water after heavy snowmelt or flash flooding.
The Gila River is a 649-mile-long (1,044 km) tributary of the Colorado River flowing through New Mexico and Arizona in the United States. The river drains an arid watershed of nearly 60,000 square miles (160,000 km2) that lies mostly within the U.S., but also extends into northern Sonora, Mexico.
The San Juan River is a major tributary of the Colorado River in the Southwestern United States, providing the chief drainage for the Four Corners region of Colorado, New Mexico, Utah, and Arizona. Originating as snowmelt in the San Juan Mountains of Colorado, it flows 383 miles (616 km) through the deserts of northern New Mexico and southeastern Utah to join the Colorado River at Glen Canyon.
The Salt River is a river in Gila and Maricopa counties in Arizona, United States, that is the largest tributary of the Gila River. The river is about 200 miles (320 km) long. Its drainage basin covers about 13,700 square miles (35,000 km2). The longest of the Salt River's many tributaries is the 195-mile (314 km) Verde River. The Salt's headwaters tributaries, the Black River and East Fork, increase the river's total length to about 300 miles (480 km). The name Salt River comes from the river's course over large salt deposits shortly after the merging of the White and Black Rivers.
The Canadian River is the longest tributary of the Arkansas River in the United States. It is about 1,026 miles (1,651 km) long, starting in Colorado and traveling through New Mexico, the Texas Panhandle, and Oklahoma. The drainage area is about 47,700 square miles (124,000 km2).
The Santa Ana River is the largest river entirely within Southern California in the United States. It rises in the San Bernardino Mountains and flows for most of its length through San Bernardino and Riverside counties, before cutting through the northern Santa Ana Mountains via Santa Ana Canyon and flowing southwest through urban Orange County to drain into the Pacific Ocean. The Santa Ana River is 96 miles (154 km) long, and its drainage basin is 2,650 square miles (6,900 km2) in size.
The San Gabriel River is a mostly-urban waterway flowing 58 miles (93 km) southward through Los Angeles and Orange Counties, California, in the United States. It is the central of three major rivers draining the Greater Los Angeles Area, the others being the Los Angeles River and Santa Ana River. The river's watershed stretches from the rugged San Gabriel Mountains to the heavily-developed San Gabriel Valley and a significant part of the Los Angeles coastal plain, emptying into the Pacific Ocean between the cities of Long Beach and Seal Beach.
The Galisteo Basin is a surface basin and a closely related groundwater basin in north-central New Mexico. Its primary watercourse is the Galisteo River or Galisteo Creek, a perennial stream, for part of its course, that flows from the eastern highlands down into the Rio Grande about three miles above the Santo Domingo Pueblo. The Galisteo basin covers approximately 467,200 acres and runs from San Miguel County in the east, across Santa Fe County, and into Sandoval County at its westernmost point, the Rio Grande. Northeast of Galisteo Basin rise the Sangre de Cristo Mountains and to the southwest lie the Sandia Mountains. Because of its location lying between mountain ranges and connecting the upper Rio Grande Valley with the Great Plains, the Galisteo Basin was used as a trade route by prehistoric and historic indigenous and later also by the Spanish explorers.
The Agua Fria River is a 120-mile (190 km) long intermittent stream which flows generally south from 20 miles (32 km) east-northeast of Prescott in the U.S. state of Arizona. Prescott draws much of its municipal water supply from the upper Agua Fria watershed. The Agua Fria runs through the Agua Fria National Monument. The river then flows through a small canyon called "Black Canyon" into Lake Pleasant, a popular recreation area near Peoria, Arizona. (There is a large "Black Canyon" on the Colorado River along the Arizona–Nevada border.)
The Big Sur River is a 15.7-mile-long (25.3 km) river on the Central Coast of California. The river drains a portion of the Big Sur area, a thinly settled region of the Central California coast where the Santa Lucia Mountains rise abruptly from the Pacific Ocean. The upper river and watershed lies within the Ventana Wilderness and encompasses the headwaters downstream to the area known as the Gorge. The lower river flows roughly northwest through Pfeiffer Big Sur State Park, the Big Sur village, several private camp grounds and Andrew Molera State Park where it flows through a lagoon and sandbar into the Pacific Ocean at the Monterey Bay National Marine Sanctuary. Major Tributaries of the river include, in order: Redwood Creek, Lion Creek, Logwood Creek, Terrace Creek, Ventana Creek, Post Creek, Pfeiffer-Redwood Creek, Juan Higuera Creek, and Pheneger Creek.
The Rio Chama, a major tributary river of the Rio Grande, is located in the U.S. states of Colorado and New Mexico. The river is about 130 miles (210 km) long altogether. From its source to El Vado Dam its length is about 50 miles (80 km), from El Vado Dam to Abiquiu Dam is about 51 miles (82 km), and from Abiquiu Dam to its confluence with the Rio Grande is about 34 miles (55 km).
The Rio Grande Trail is a proposed long distance trail along the Rio Grande in the U.S. state of New Mexico. The river extends over 1,800 total miles, some 700 miles (1,100 km) of which pass through the heart of New Mexico. It is the state's primary drainage feature and most valuable natural and cultural resource. The river and its bosque provide a wide variety of recreation, including hunting and fishing, birdwatching, river rafting, hiking, biking, and horseback riding. The river also flows through or beside numerous spectacular and geologically interesting landforms, the result of extensive volcanism and erosion of the valley within the Rio Grande Rift. Although some trail advocates would like to see the trail extended the full distance through New Mexico, from the Colorado border to the United States–Mexico border, the portion proposed for initial development extends 300 miles (480 km), from Bernalillo south to Las Cruces.
Caja del Rio is a dissected plateau, of volcanic origin, which covers approximately 84,000 acres of land in northern Santa Fe County, New Mexico, United States. The region is also known as the Caja, Caja del Rio Plateau, and Cerros del Rio. The center of the area is approximately 15 miles (23 km) west of Santa Fe, New Mexico. Most of the Caja is owned by the United States Forest Service and managed by the Santa Fe National Forest. Access is through New Mexico Highway 599, Santa Fe County Road 62, and Forest Service Road 24.
Santiago Creek is a major watercourse in Orange County in the U.S. state of California. About 34 miles (55 km) long, it drains most of the northern Santa Ana Mountains and is a tributary to the Santa Ana River. It is one of the longest watercourses entirely within the county. The creek shares its name with Santiago Peak, at 5,687 ft (1,733 m) the highest point in Orange County, on whose slopes its headwaters rise.
The Red River of New Mexico, United States, is a short, perennial river that flows down the north slope of Mount Wheeler in the Sangre de Cristo Mountains, flows west past the towns of Red River and Questa and then south into the Rio Grande just south of the La Junta Campground. The Red River is Taos's winter fishery with prime time being from October through early April. The Red provides visitors the unique opportunity to fish and ski on the same trip. A myriad of springs flow into the river greatly increasing the flows and keeping the water temperatures in the optimum trout fishing range of between 45 and 60 degrees making the Red an ideal winter trout fishery.
The Jemez River is a tributary of the Rio Grande in eastern Sandoval County, New Mexico, United States.
The San Juan–Chama Project is a U.S. Bureau of Reclamation interbasin water transfer project located in the states of New Mexico and Colorado in the United States. The project consists of a series of tunnels and diversions that take water from the drainage basin of the San Juan River – a tributary of the Colorado River – to supplement water resources in the Rio Grande watershed. The project furnishes water for irrigation and municipal water supply to cities along the Rio Grande including Albuquerque and Santa Fe.
San Acacia is a small unincorporated community and census-designated place in Socorro County, New Mexico, United States. It was once a prosperous railway town, but is now largely deserted. There is a nearby diversion dam on the Rio Grande, important in irrigation.
