SALADO RIVER

Spanish Ro Salado river in northeastern Buenos Aires province, Argentina. It rises at Lake El Chaar, which lies at an elevation of 130 feet (40 m) above sea level on the border of Santa Fe province. The river flows through the Pampas, generally southeastward for approximately 400 miles (640 km) to the Atlantic Ocean, where it empties into Samborombn Bay, 105 miles (170 km) southeast of the city of Buenos Aires. The river's meandering course past the cities of Junn, Roque Prez, and General Belgrano often flows through small lakes and marshland. Peripheral canalization of the lower course has improved the river's drainage system. Before 1800 the Salado marked the frontier between Spanish colonization (to the northeast) and indigenous Indians (to the southwest). Spanish Ro Salado, river in northeastern Mexico. It rises in the Sierra Madre Oriental in Coahuila state and flows generally east-northeastward for some 175 miles (280 km) into the lake created by the Venustiano Carranza Dam at Don Martn. Leaving the reservoir, the Salado, joined by the Sabinas River, winds southeastward for 110 miles (175 km) through northern Nuevo Len and northwestern Tamaulipas states and joins the Falcn Reservoir on the Rio Grande (Ro Bravo del Norte) opposite Zapata, Texas. The Salado is economically important, for its waters are used extensively for irrigation, particularly for cotton growing.
