Union Mills Canal Outlet Locks No. 1 And No. 2
The Union Mills Canal Outlet Locks No. 1 and No. 2 are a pair of lock (water transport), locks along the route of a canal system that improved navigation on the Rivanna River in Fluvanna County, Virginia. Located near Crofton, Virginia, Crofton, they are two large locks fashioned out of dressed granite blocks. They were built between 1850 and 1854. Until the 1850s, canal and river transportation primarily employed Bateau, batteaux, but mid-century saw the construction of towpaths to enable mules to pull boats. It was for this purpose that the Union Mills Canal and its outlet locks were constructed. The canal is approximately long, with a lock and dam complex at the upper end; it runs on the Bank (geography), right bank of the river.Trout, W.E., III. ''The Rivanna scenic river atlas''. Lexington, Virginia, Lexington: Virginia Canals and Navigations Society, 1995. The outlet locks, situated at the lower end of the canal, are located just above the mouth of a small stream, Bos ...

Lock (water Transport)
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 n ...

Rivanna River
The Rivanna River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed April 1, 2011 tributary of the James River in central Virginia in the United States. The Rivanna's tributaries originate in the Blue Ridge Mountains; via the James River, it is part of the watershed of Chesapeake Bay. According to the Geographic Names Information System, the Rivanna has also been known as "Mountain Falls Creek" and "River Anna". Course The Rivanna River is formed in Albemarle County about northeast of Charlottesville by the confluence of two tributaries: *The North Fork Rivanna River is formed in southwestern Greene County by the confluence of the Lynch River and the Roach River, and flows southeast by south into Albemarle County. *The South Fork Rivanna River is formed in Albemarle County by the confluence of the Moormans River and the Mechums River, and flows generally eastwardly. Below this confluence, the Rivanna flows s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluvanna County, Virginia
Fluvanna County is a county located in the Piedmont region of the Commonwealth of Virginia. As of the 2020 census, the population was 27,249. Its county seat is Palmyra, while the most populous community is the census designated place of Lake Monticello. Fluvanna County is part of the Charlottesville, Virginia Metropolitan Statistical Area. History Through the 17th century, the Point of Fork (near Columbia where the James and Rivanna rivers meet) was the site of ''Rassawek'', a major Monacan village of the Native Americans. By 1701, the Seneca Iroquois had overrun the entire Virginia Piedmont, which they sold to Virginia Colony in 1721 at the Treaty of Albany. The area which is now Fluvanna County was once considered part of Henrico County, one of the original shires of the Virginia Colony. Henrico was divided in 1727 and the Fluvanna County area became a part of Goochland County. In 1744 Goochland was divided and the area presently known as Fluvanna became a part of A ...

Bateau
A bateau or batteau is a shallow- draft, flat-bottomed boat which was used extensively across North America, especially in the colonial period and in the fur trade. It was traditionally pointed at both ends but came in a wide variety of sizes. The name derives from the French word, ''bateau'', which is simply the word for boat and the plural, bateaux, follows the French, an unusual construction for an English plural. In the southern United States, the term is still used to refer to flat-bottomed boats, including those elsewhere called jon boats. Construction Bateaux were flat-bottomed and double-ended. They were built with heavy stems at bow and stern and a series of frames amidships, likely from natural oak crooks when available, and planked with sawn boards, likely pine although builders would have used whatever material was available. These boats would have varied from place to place, from builder to builder and also evolved over time, however in general, they were long an ...

Towpath
A towpath is a road or trail on the bank of a river, canal, or other inland waterway. The purpose of a towpath is to allow a land vehicle, beasts of burden, or a team of human pullers to tow a boat, often a barge. This mode of transport was common where sailing was impractical due to tunnels and bridges, unfavourable winds, or the narrowness of the channel. After the Industrial Revolution, towing became obsolete when engines were fitted on boats and when railway transportation superseded the slow towing method. Since then, many of these towpaths have been converted to multi-use trails. They are still named towpaths — although they are now only occasionally used for the purpose of towing boats. History Early inland waterway transport used the rivers, and while barges could use sails to assist their passage when winds were favourable or the river was wide enough to allow tacking, in many cases this was not possible, and gangs of men were used to bow-haul the boats.

Mule
The mule is a domestic equine hybrid between a donkey and a horse. It is the offspring of a male donkey (a jack) and a female horse (a mare). The horse and the donkey are different species, with different numbers of chromosomes; of the two possible first-generation hybrids between them, the mule is easier to obtain and more common than the hinny, which is the offspring of a female donkey (a jenny) and a male horse (a stallion). Mules vary widely in size, and may be of any color. They are more patient, hardier and longer-lived than horses, and are perceived as less obstinate and more intelligent than donkeys. Terminology A female mule that has oestrus cycles, and which could thus in theory carry a foetus, is called a "molly" or "Molly mule", though the term is sometimes used to refer to female mules in general. A male mule is properly called a "horse mule", though often called a "john mule", which is the correct term for a gelded mule. A young male mule is called a "mule co ...

Bank (geography)
In geography, a bank is the land alongside a body of water. Different structures are referred to as ''banks'' in different fields of geography, as follows. In limnology (the study of inland waters), a stream bank or river bank is the terrain alongside the bed of a river, creek, or stream. The bank consists of the sides of the channel, between which the flow is confined. Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them. Bankfull discharge is a discharge great enough to fill the channel and overtop the banks. The descriptive terms ''left bank'' and ''right bank'' refer to the perspective of an observer looking downstream; a well-known example of this being the sections of Paris as defined by the river Seine. The shoreline of ponds, swamps, estuaries, reservoirs, or lakes are also of interest in limnology and are sometimes referred to as banks. The ...

Silt
Silt is granular material of a size between sand and clay and composed mostly of broken grains of quartz. Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension with water. Silt usually has a floury feel when dry, and lacks plasticity when wet. Silt also can be felt by the tongue as granular when placed on the front teeth (even when mixed with clay particles). Silt is a common material, making up 45% of average modern mud. It is found in many river deltas and as wind-deposited accumulations, particularly in central Asia, north China, and North America. It is produced in both very hot climates (through such processes as collisions of quartz grains in dust storms) and very cold climates (through such processes as glacial grinding of quartz grains.) Loess is soil rich in silt which makes up some of the most fertile agricultural land on Earth. However, silt is very vulnerable to erosion, and it has poor mechanical properties, making construc ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
