25-518: The river is formed near the community of Rock Cave in southwestern Upshur County by the confluence of small headwaters tributaries known as Straight Fork and Whites Camp Fork. From this confluence the West Fork River flows north through Lewis , Harrison and Marion counties, through the communities of Weston , West Milford , Clarksburg , Lumberport , Shinnston , Enterprise , Worthington , and Monongah to Fairmont , where it joins

50-768: A 4-H facility since the 1920s. A walking trail parallels the river for 1.2 miles (2 km) in Veteran's Park in Clarksburg. For much of its length between Clarksburg and Fairmont, the West Fork is paralleled by a pair of rail trails on the route of a mid-19th century line of the Baltimore and Ohio Railroad . The Harrison County Trail extends northward from Clarksburg, and the West Fork River Trail connects Shinnston to Fairmont. A long-term closure of

75-679: A dash ; for example, 1-21-00.26 ha would mean 1 hectare, 21 ares, and 0.26 centiares (12,100.26 m ). The metric system of measurement was first given a legal basis in 1795 by the French Revolutionary government. The law of 18 Germinal, Year III (7 April 1795) defined five units of measure: In 1960, when the metric system was updated as the International System of Units (SI), the are did not receive international recognition. The International Committee for Weights and Measures ( CIPM ) makes no mention of

100-404: A double prefix is non-standard. The decimilliare is (100 mm) or roughly a four-inch-by-four-inch square. The centiare is one square metre. The deciare (rarely used) is ten square metres. The are ( / ɑːr / or / ɛər / ) is a unit of area, equal to 100 square metres ( 10 m × 10 m ), used for measuring land area. It was defined by older forms of the metric system , but

125-439: A few other units including the are (and implicitly the hectare ) whose use was limited to the measurement of land. The names centiare , deciare , decare and hectare are derived by adding the standard metric prefixes to the original base unit of area, the are . The decimilliare (dma, sometimes seen in cadastre area evaluation of real estate plots) is 1 ⁄ 10,000 are or one square decimetre. Such usage of

150-550: A measure of land area. The names of the older land measures of similar size are usually used, redefined as exactly one decare: The most commonly used units are in bold . One hectare is also equivalent to: The Unicode character U+33CA ㏊ SQUARE HA , in the CJK Compatibility block, is intended for compatibility with pre-existing East Asian character codes. It is not intended for use in alphabetic contexts. U+3336 ㌶ SQUARE HEKUTAARU

175-466: A non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m ) and are (100 m ) are not officially "accepted for use", they are still used in some contexts. The hectare ( / ˈ h ɛ k t ɛər , - t ɑː r / ), although not a unit of SI, is the only named unit of area that is accepted for use with SI units . The name

200-490: Is 95 feet (29 m) tall and forms a 2,650-acre (1,070  ha ) lake, with a larger capacity during periods of flood. Land along the lake is leased as a wildlife management area and Stonewall Jackson Lake State Park . Between the years of 1905 and 1931, four small dams were constructed by the Clarksburg Water Board on a sixteen-mile (26 km) stretch of the river upstream (south) of Clarksburg, for

225-526: Is a census designated unincorporated community in Upshur County , West Virginia , United States. The town is located southwest of Buckhannon at the junction of West Virginia Route 4 with County Routes 11/2 and 20/28. Throughout the community's history, Rock Cave has been known as Bob Town , Centerville , and Centreville . The community's name is a corruption of Rock Lava, which referred to rocks purportedly of volcanic origin unearthed near

250-475: Is a stub . You can help Misplaced Pages by expanding it . Hectare The hectare ( / ˈ h ɛ k t ɛər , - t ɑːr / ; SI symbol: ha ) is a non-SI metric unit of area equal to a square with 100- metre sides (1 hm ), that is, 10,000 square metres (10,000 m ), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about 0.405 hectares and one hectare contains about 2.47 acres. In 1795, when

275-543: Is claimed to have improved public safety, recreation access, water quality, and ecological connectivity. The United States Board on Geographic Names settled on "West Fork River" as the stream's name in 1902. According to the Geographic Names Information System , the West Fork River has also been known historically as: [REDACTED] Media related to West Fork River at Wikimedia Commons Rock Cave, West Virginia Rock Cave

Other fish species in the river include carp ; channel and flathead catfish ; golden and rainbow trout ; largemouth , smallmouth , and spotted bass ; sauger ; and walleye . Jackson's Mill was established along the river north of Weston around the year 1800 by Edward Jackson; his grandson and future confederate general Thomas "Stonewall" Jackson lived there during much of his youth. The site has been operated as

325-456: Is now outside the modern International System of Units (SI). It is still commonly used in speech to measure real estate, in particular in Indonesia, India, and in various European countries. In Russian and some other languages of the former Soviet Union , the are is called sotka (Russian: сотка : 'a hundred', i.e. 100 m or 1 ⁄ 100 hectare). It is used to describe

350-1151: The European Union , New Zealand and Australia (since 1970). However, the United Kingdom, the United States, Myanmar (Burma), and to some extent Canada, use the acre instead of the hectare for measuring surface or land area. Some countries that underwent a general conversion from traditional measurements to metric measurements (e.g. Canada) required a resurvey when units of measure in legal descriptions relating to land were converted to metric units. Others, such as South Africa, published conversion factors which were to be used particularly "when preparing consolidation diagrams by compilation". In many countries, metrification redefined or clarified existing measures in terms of metric units. The following legacy units of area have been redefined as being equal to one hectare: In Mexico, land area measurements are commonly given as combinations of hectares, ares, and centiares. These are commonly written separated by

375-666: The Tygart Valley River from the west to form the Monongahela River. (The Tygart is thus the "East Fork" of the Monongahela.) Among other tributaries, it collects Stonecoal Creek in Weston; Hackers Creek in southern Harrison County; Elk Creek in Clarksburg; and Simpson Creek and Tenmile Creek in northern Harrison County. The West Fork has a low gradient and is slow-moving throughout its course. It

400-593: The are in the 2019 edition of the SI brochure, but classifies the hectare as a "Non-SI unit accepted for use with the International System of Units". In 1972, the European Economic Community (EEC) passed directive 71/354/EEC, which catalogued the units of measure that might be used within the Community. The units that were catalogued replicated the recommendations of the CGPM, supplemented by

450-557: The United States, the government of Virginia attempted to maintain commercial navigability on the river, chartering a company for that purpose in 1793 and requiring that dams for milling operations provide a chute for boats to pass downstream. Construction of a system of locks , dams, and chutes was begun by the Monongahela Navigation Company in 1817; the project was abandoned following damage by floods in 1824. Three miles (4.8 km) south of Weston,

475-480: The connection between the two trails is anticipated, due to the presence of hazardous waste at an industrial site near the community of Spelter in northern Harrison County. The West Fork River is not navigable by commercial barge traffic; it is classified by the West Virginia Division of Natural Resources as "recreationally navigable" for canoes and similar craft. During the early history of

500-487: The metric system was introduced, the are was defined as 100 square metres , or one square decametre , and the hectare (" hecto- " + "are") was thus 100 ares or 1 ⁄ 100  km (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units ( SI ), the are was not included as a recognised unit. The hectare, however, remains as

525-461: The provision of local drinking water. While the dams in later years have come to be regarded as good fishing areas, the Water Board is working with the U.S. Fish and Wildlife Service on plans to remove them. In 2016 removal of three of the dams was completed in an effort led by U.S. Fish and Wildlife Service, the removed dams being: West Milford, Two Lick, and Highland Dams. Removal of the dams

550-492: The river is dammed by the U.S. Army Corps of Engineers to form Stonewall Jackson Lake . The project was authorized by the federal Flood Control Act of 1966 for flood control, improvement of water quality and water supply , improvement of habitat for fish and wildlife, hydropower , and recreation. Construction of the dam was delayed by the opposition of local residents and began in the mid-1980s at an ultimate cost of $ 208 million; it became fully operational in 1988. The dam

575-595: The size of suburban dacha or allotment garden plots or small city parks where the hectare would be too large. Many Russian dachas are 6 ares in size (in Russian, шесть соток ). The decare or dekare ( / ˈ d ɛ k ɑːr , - ɛər / ) is derived from deca and are , and is equal to 10 ares or 1000 square metres. It is used in Norway and in the former Ottoman areas of the Middle East and Bulgaria as
