Fort Peck Dam
The Fort Peck Dam is the highest of six major dams along the Missouri River, located in northeast Montana in the United States, near Glasgow, and adjacent to the community of Fort Peck. At in length and over in height, it is the largest hydraulically filled dam in the United States, and creates Fort Peck Lake, the fifth largest artificial lake in the U.S., more than long, deep, and it has a shoreline which is longer than the state of California's coastline. It lies within the Charles M. Russell National Wildlife Refuge. The dam and the lake are owned and operated by the U.S. Army Corps of Engineers and exist for the purposes of hydroelectric power generation, flood control, and water quality management. The dam presently has a nameplate capacity of 185.25 megawatts, divided among 5 generating units (which in turn are divided between the Western and Eastern grids).

A fortification (also called a fort, fortress, fastness, or stronghold) is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin ("strong") and ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley Civilization were the first small cities to be fortified. In ancient Greece, large cyclopean stone walls fitted without mortar had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek ''Towns of ancient Greece#Military settlements, phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the ancient Roman, Roman castellum or fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Randall Dam
Fort Randall Dam is a earthen dam which spans the Missouri River and impounds Lake Francis Case, the 11th-largest reservoir in the U.S. The dam joins Gregory and Charles Mix counties, South Dakota, a distance of 880 river miles (1,416 km) upstream of St. Louis, Missouri, where the river joins the Mississippi River. The dam and hydroelectric power plant were constructed by and are currently operated by the U.S. Army Corps of Engineers.

The U.S. Army Corps of Engineers began construction of the dam in 1946, and was the first Pick–Sloan dam completed by the Omaha District. President Dwight D. Eisenhower threw the switch that started the first power generating unit in 1954. When completed in 1956, Fort Randall Dam and the Lake Francis Case Project cost approximately $200 million. ...

Oahe Dam
The Oahe Dam () is a large earthen dam on the Missouri River, just north of Pierre, South Dakota, Pierre, South Dakota, United States. Begun in 1948 and opened in 1962, the dam creates Lake Oahe, the fourth-largest man-made reservoir in the United States.

Main Stem
In hydrology, a main stem or mainstem (also known as a trunk) is "the primary downstream segment of a river, as contrasted to its tributaries". The mainstem extends all the way from one specific headwater to the outlet of the river, although there are multiple ways to determine which headwater (or first-order tributary) is the source of the main stem. Water enters the main stem from the river's drainage basin, the land area through which the mainstem and its tributaries flow.. A drainage basin may also be referred to as a ''watershed'' or ''catchment''. Hydrological classification systems assign numbers to tributaries and mainstems within a drainage basin. In the Strahler number, a modification of a system devised by Robert E. Horton in 1945, channels with no tributaries are called "first-order" streams. When two first-order streams meet, they are said to form a second-order stream; when two second-order streams meet, they form a third-order stream, and so on. In the Horton ...
