This is a list of rivers in El Salvador .
El Salvador has 58 river basins which all drain to the Pacific Ocean.The total amount of water discharged into the Pacific is 19 million m³ in a normal year. Additionally, there are several endorheic basins linked to a lake. Coatepeque Lake is the largest endorheic basin in the country.
This list is arranged by drainage basin, with respective tributaries indented under each larger stream's name.
The Continental Divide of the Americas is the principal, and largely mountainous, hydrological divide of the Americas. The Continental Divide extends from the Bering Strait to the Strait of Magellan, and separates the watersheds that drain into the Pacific Ocean from those river systems that drain into the Atlantic Ocean and, along the northernmost reaches of the Divide, those river systems that drain into the Arctic Ocean and Hudson Bay.
A drainage basin is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water. The drainage basin includes all the surface water from rain runoff, snowmelt, hail, sleet and nearby streams that run downslope towards the shared outlet, as well as the groundwater underneath the earth's surface. Drainage basins connect into other drainage basins at lower elevations in a hierarchical pattern, with smaller sub-drainage basins, which in turn drain into another common outlet.
Tulare Lake is a freshwater dry lake with residual wetlands and marshes in the southern San Joaquin Valley, California, United States. After Lake Cahuilla disappeared in the 17th century, Tulare Lake was the largest freshwater lake west of the Mississippi River and the second-largest freshwater lake entirely in the United States, based upon surface area. A remnant of Pleistocene-era Lake Corcoran, Tulare Lake dried up after its tributary rivers were diverted for agricultural irrigation and municipal water uses.
Santa Ana is the second largest city in El Salvador, after the capital of San Salvador. It is located 64 kilometers northwest of San Salvador, the capital city. Santa Ana has approximately 374,830 (2017)) inhabitants and serves both as the capital of the department of Santa Ana and as the municipal seat for the surrounding municipality of the same name. For its administration the municipality is divided into 35 colonias (neighborhoods) and 318 small villages.
An endorheic basin is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins or internal drainage systems or basins. Endorheic regions contrast with exorheic regions. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water.
Badwater Basin is an endorheic basin in Death Valley National Park, Death Valley, Inyo County, California, noted as the lowest point in North America and the United States, with a depth of 282 ft (86 m) below sea level. Mount Whitney, the highest point in the contiguous 48 United States, is only 84.6 miles (136 km) to the northwest.
The Santiago River or Río Grande de Santiago is one of the longest rivers in Mexico, measuring up 433 km (269 mi) long. The river begins at Lake Chapala and continues roughly north-west through the Sierra Madre Occidental, receiving the Verde, Juchipila, Bolaños, and other tributaries. At La Yesca, the La Yesca Dam was completed in 2012 and the El Cajón Dam was completed downstream in 2007. Below El Cajón, the Aguamilpa Dam was completed in 1993, creating a reservoir covering a large part of the territory of the municipality of El Nayar in Nayarit. From Aguamilpa, the river descends to the coastal lowlands, passing by Santiago Ixcuintla and empties into the Pacific Ocean, 16 km (10 mi) northwest of San Blas, in Nayarit.
The Matanza River is known by several names, including, in Spanish, Río de la Matanza, Río Matanza, Río Mataderos, Río de la Manzana or simply Riachuelo. It is a 64-kilometre (40 mi) stream in Argentina that originates in the Buenos Aires Province and defines the southern boundary of the Buenos Aires federal district. It empties into the Río de la Plata between Tandanor and Dock Sud. The La Boca neighbourhood and the Boca Juniors football club are located near the Riachuelo's mouth. The Spanish word boca means "mouth".
The San Jacinto River is a 42-mile-long (68 km) river in Riverside County, California. The river's headwaters are in Santa Rosa and San Jacinto Mountains National Monument. The lower portion of the 765-square-mile (1,980 km2) watershed is urban and agricultural land. As a partially endorheic watershed that is contiguous with other Great Basin watersheds, the western side of the San Jacinto Basin is a portion of the Great Basin Divide.
A continental divide is a drainage divide on a continent such that the drainage basin on one side of the divide feeds into one ocean or sea, and the basin on the other side either feeds into a different ocean or sea, or else is endorheic, not connected to the open sea. Every continent on earth except Antarctica has at least one continental drainage divide; islands, even small ones like Killiniq Island on the Labrador Sea in Canada, may also host part of a continental divide or have their own island-spanning divide.
The Lempa River is a 422-kilometre (262 mi) long river in Central America.
Water resources management in El Salvador is characterized by difficulties in addressing severe water pollution throughout much of the country's surface waters due to untreated discharges of agricultural, domestic and industrial run off. The river that drains the capital city of San Salvador is considered to be polluted beyond the capability of most treatment procedures.
Watersheds of North America are large drainage basins which drain to separate oceans, seas, gulfs, or endorheic basins. There are six generally recognized hydrological continental divides which divide the continent into seven principal drainage basins spanning three oceans and one endorheic basin. The basins are the Atlantic Seaboard basin, the Gulf of Mexico basin, the Great Lakes-St. Lawrence basin, the Pacific basin, the Arctic basin, the Hudson Bay basin, and the Great Basin. Together, the principal basins span the continent with the exception of numerous smaller endorheic basins.
The Cerrón Grande Reservoir, also known locally as Lake Suchitlán, is a reservoir in northern El Salvador and the largest body of fresh water in the country. The reservoir was filled between 1973 and 1976, subsequent to the construction of the Cerrón Grande Hydroelectric Dam. The Cerrón Grande Reservoir is among the most polluted bodies of fresh water in Central America.
