Wilbur D. Mills Dam
Wilbur D. Mills Dam is a steel dam and generating facility located on the Arkansas River in Arkansas County and Desha County, Arkansas, United States. The dam is part of the McClellan–Kerr Arkansas River Navigation System, and is named for Wilbur D. Mills, a member of United States House of Representatives from Arkansas. Design Wilbur D. Mills Dam is high, and consists of a long earthen embankment, a long high-level overflow, and a long spillway. History The course of the lower Arkansas River changes significantly downstream from the location of the dam, where the river follows a long winding route until it reaches its outflow at the Mississippi River, approximately southeast. This circuitous portion of the Arkansas River between the current dam location and the Mississippi River was historically bypassed by river vessels; early steamboats instead followed a network of rivers—known as the Arkansas Post Canal—which flowed north of the lower Arkansas River, and follow ...

Arkansas County, Arkansas
Arkansas County is a county located in the U.S. state of Arkansas. As of the 2010 census, the population was 19,019. Located in the Arkansas Delta, the county has two county seats, DeWitt and Stuttgart. The first of the state's 75 present-day counties to be created, Arkansas County was formed on December 13, 1813, when this area was part of the Missouri Territory. The county was named after the Arkansas River (itself named for the Arkansas tribe), as was the subsequent Arkansas Territory. This was later split off from Missouri Territory and eventually admitted to the union as a state. The riverfront areas in the Arkansas Delta were developed for cotton plantations, based on the use of enslaved African Americans. Cotton was the major commodity crop before and after the Civil War. Since then, the county lies within the largest rice-growing region in the United States. Arkansas County is one of seven present-day counties in the United States that have the same name as the st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desha County, Arkansas
Desha County ( ) is a county located in the southeast part of the U.S. state of Arkansas, with its eastern border the Mississippi River. At the 2010 census, the population was 13,008. It ranks 56th of Arkansas's 75 counties in terms of population. The county seat is Arkansas City. Located in the Arkansas Delta, Desha County's rivers and fertile soils became prosperous for planters under the cotton-based economy of plantation agriculture in the antebellum years and late 19th century. Still largely rural, it has suffered population losses and economic decline since the mid-20th century. But following widespread farm mechanization, Desha County underwent a demographic and economic transformation. Farm workers left the area because of the lack of work, and there was a decline in population. Farm holdings have been consolidated into industrial style farms and the economy cannot support much activity. In the 21st century, the county is seeking to reverse population and economic losse ...

Barrage (dam)
A barrage is a type of low-head, diversion dam which consists of a number of large gates that can be opened or closed to control the amount of water passing through. This allows the structure to regulate and stabilize river water elevation upstream for use in irrigation and other systems. The gates are set between flanking piers which are responsible for supporting the water load of the pool created. The term '' barrage'' is borrowed from the French word "barrer" meaning "to bar". Dam construction Barrage dams have a series of gates that control the amount of water passing through it. A barrage dam can be used to divert water for irrigation needs or limit the amount of water down-stream. In most cases, a barrage dam is built near the mouth of the river. The site of dam construction needs to be thoroughly investigated to ensure that the foundation is strong enough to support the dam and has low possibility of failing. When dams are created, they are given a safety rating dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arkansas River
The Arkansas River is a major tributary of the Mississippi River. It generally flows to the east and southeast as it traverses the U.S. states of Colorado, Kansas, Oklahoma, and Arkansas. The river's source basin lies in the western United States in Colorado, specifically the Arkansas River Valley. The headwaters derive from the snowpack in the Sawatch and Mosquito mountain ranges. It flows east into the Midwest via Kansas, and finally into the South through Oklahoma and Arkansas. At , it is the sixth-longest river in the United States, the second-longest tributary in the Mississippi–Missouri system, and the 45th longest river in the world. Its origin is in the Rocky Mountains in Lake County, Colorado, near Leadville. In 1859, placer gold discovered in the Leadville area brought thousands seeking to strike it rich, but the easily recovered placer gold was quickly exhausted. The Arkansas River's mouth is at Napoleon, Arkansas, and its drainage basin covers nearly .See wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel Dam
A steel dam is a type of dam (a structure to impound or retard the flow of water) that is made of steel, rather than the more common masonry, earthworks, concrete or timber construction materials. Relatively few examples were ever built. Of the three built in the US, two remain: the Ashfork-Bainbridge Steel Dam, built in 1898 in the Arizona desert to supply locomotive water to the Atchison, Topeka and Santa Fe Railway (ATSF), and the Redridge Steel Dam, built 1901, in the Upper Peninsula of Michigan to supply water to stamp mills. The third, the Hauser Lake Dam in Montana, was finished in 1907 but failed in 1908. Steel dams were found to be uneconomical after World War I, as the price of steel increased by many multiples, compared with cement prices. Their economics are highly favourable in 21st century due to lower total onsite labour costs, lower cost for bulk material transportation, availability of more construction time in a year, and flexibility in construction plan compl ...

Mississippi River
The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.

Lock (water Navigation)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls. Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Later canals used more and larger locks to allow a more direct route to be taken. Pound lock A ''pound lock'' is most commonly used on canals and rivers today. A pound lock has a chamber with gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a flash lock. Pound locks were first used in China during the Song Dynasty (960–1279 AD), having been pioneered by the Song politician and naval ...
