The South Platte River is one of the two principal tributaries of the Platte River. Flowing through the U.S. states of Colorado and Nebraska, it is itself a major river of the American Midwest and the American Southwest/Mountain West. Its drainage basin includes much of the eastern flank of the Rocky Mountains in Colorado; much of the populated region known as the Colorado Front Range and Eastern Plains; and a portion of southeastern Wyoming in the vicinity of the city of Cheyenne. It joins the North Platte River in western Nebraska to form the Platte, which then flows across Nebraska to the Missouri. The river serves as the principal source of water for eastern Colorado. In its valley along the foothills in Colorado, it has permitted agriculture in an area of the Colorado Piedmont and Great Plains that is otherwise arid.
A dam is a barrier that stops or restricts the flow of water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC.

The Pecos River originates in north-central 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. 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).
The Gunnison River is a tributary of the Colorado River, 180 miles (290 km) long, in the Southwestern state of Colorado. It is the largest tributary of the Colorado River in Colorado, with a mean flow of 2,570 cu ft/s (73 m3/s).
Calaveras Reservoir is located primarily in Santa Clara County, California, with a small portion and its dam in Alameda County, California. In Spanish, Calaveras means "skulls".
A reservoir is, most commonly, an enlarged natural or artificial lake, pond, or impoundment created using a dam or lock to store water.
The San Luis Reservoir is an artificial lake on San Luis Creek in the eastern slopes of the Diablo Range of Merced County, California, approximately 12 mi (19 km) west of Los Banos on State Route 152, which crosses Pacheco Pass and runs along its north shore. It is the fifth largest reservoir in California. The reservoir stores water taken from the San Joaquin-Sacramento River Delta. Water is pumped uphill into the reservoir from the O'Neill Forebay which is fed by the California Aqueduct and is released back into the forebay to continue downstream along the aqueduct as needed for farm irrigation and other uses. Depending on water levels, the reservoir is approximately nine miles long from north to south at its longest point, and five miles (8 km) wide. At the eastern end of the reservoir is the San Luis Dam, or the B.F. Sisk Dam, the fourth largest embankment dam in the United States, which allows for a total capacity of 2,041,000 acre feet (2,518,000 dam3).
Amistad Reservoir is a reservoir on the Rio Grande at its confluence with the Devils River 12 miles (19 km) northwest of Del Rio, Texas. The lake is bounded by Val Verde County on the United States side of the international border and by the state of Coahuila on the Mexican side of the border; the American shoreline forms the Amistad National Recreation Area. The reservoir was formed in 1969 by the construction of Amistad Dam. The dam and lake are managed jointly by the governments of the United States and Mexico through the International Boundary and Water Commission. The name of the dam and lake is the Spanish word for "friendship". The reservoir is also known as Lake Amistad.
Lake Del Valle is a storage reservoir located 10 miles (16 km) southeast of Livermore, in Alameda County, California. It is within Del Valle Regional Park.
Riaño is a former small municipality located along the Esla River in the mountains of the province of León, in the autonomous community of Castile and León, northern Spain. The village was across the river from Peak Gilbo. Located 3650 feet above sea level, it is in the Cantabrian mountains near the foothills of the Picos de Europa.
Marun Dam, also spelled Maroun, is a rock-fill embankment dam on the Marun River about 15 km (9.3 mi) north of Behbahan in Behbahan County, Khuzestan Province, Iran. The dam serves to provide water for irrigation and to generate hydroelectric power as well. Construction on the dam began in 1989 and it was completed in 1998. A smaller Marun-II regulator dam is planned downstream. The 150 MW power station was commissioned in 2004.
Marion Reservoir is a body of water on the Cottonwood River, 3 miles (4.8 km) north-west of Marion, on the western edge of the Flint Hills region of Kansas in the United States. It was completed in 1968 and is operated by the Army Corps of Engineers for the purpose of flood control.
