41-708: The Sehlabathebe National Park is located in the Maloti Mountains in Qacha's Nek District , Lesotho and is part of the Maloti-Drakensberg World Heritage Site . The park was first established on 8 May 1969 and since then, is recognised as important in terms of biological diversity and cultural heritage. The landscape is dominated by grasslands of various types. The larger ecosystem functions provide freshwater to Lesotho , South Africa , and Namibia . Sehlabathebe National Park
82-797: A mountain range of the highlands of the Kingdom of Lesotho . They extend for about 100 km into the South African Free State . The Maloti Range is part of the Drakensberg system that includes ranges across large areas of South Africa . "Maloti" is also the plural for Loti , the currency of the Kingdom of Lesotho. The range forms the northern portion of the boundary between the Butha-Buthe District in Lesotho and South Africa's Free State . The range forms
123-606: A velar fricative in place of the alveolar click , Groote River (derived from Kai !Garib ) or Senqu River (used in Lesotho), derived from ǂNū "Black". It is known in isiZulu as isAngqu. The Orange rises in the Drakensberg mountains along the border between South Africa and Lesotho, about 193 km (120 mi) west of the Indian Ocean and at an altitude of over 3,000 m (9,800 ft). The extremity of

The highest point, 3,482 m (11,424 ft) high Thabana Ntlenyana , is located in the north-east of the range. It is the highest peak of Southern Africa , and the highest in Africa south of the Kilimanjaro . The 3,291 m (10,797 ft) high Namahadipiek ,
205-550: A natural pipe through which the diamonds gradually enter the river. Other sites said to be lairs of the creature include the pool beneath the King George Cataract at Aughrabies Falls , which is also said to be a source of diamonds, and a large rock in the middle of the river itself. In this version of the legend, the Grootslang is also said to prey on cattle from the river's banks. As the collection point for
246-537: A strong association with the history of colonial subjugation and has therefore no place under the current democratic dispensation." In South African folklore, the Orange River is often associated with the Grootslang , a mythical being resembling a giant serpent, which is often connected to the river's alluvial diamonds. The Grootslang is described as living in a gem-filled cave connected to the Orange River by
287-944: Is a river in Southern Africa . It is the longest river in South Africa . With a total length of 2,432 km (1,511 mi), the Orange River Basin extends from Lesotho into South Africa and Namibia to the north. It rises in the Drakensberg mountains in Lesotho, flowing westwards through South Africa to the Atlantic Ocean . The river forms part of the international borders between South Africa and Lesotho and between South Africa and Namibia, as well as several provincial borders within South Africa. Except for Upington , it does not pass through any major cities. The Orange River plays an important role in
328-780: Is endemic to the park, the Cape vulture and the bearded vulture . The Sehlabathebe water lily is an endangered aquatic plant. This site was added to the UNESCO World Heritage Site Tentative List on October 8, 2008, in the Mixed (Cultural + Natural) category. Sehlabathebe is currently run under the Ministry of Tourism, Environment, and Culture jurisdiction. The park has also been recognised as an Important Bird Area (IBA) by BirdLife International . Maloti Mountains The Maloti Mountains are
369-460: Is generally not navigable for long stretches. The river has a total length of 2,432 km (1,511 mi). In the dry season , the volume of the water in the river is considerably reduced because of the rapid run-off and evaporation . At the source of the Orange, the rainfall is about 2,000 mm (79 in) per annum, but precipitation decreases as the river flows westward; at its mouth,
410-445: Is situated in the south-east corner of Lesotho at an average elevation of some 2,400 metres above sea level. Most of the park is taken up by a designated wilderness area, and is uninhabited. Much of it consists of cliffs, waterfalls, pools, rock dwellings and rock art. It is known for its scenery with unique rock formations. The Tsoelikane waterfall is the biggest waterfall in the park. A total of 65 rock art sites have been identified in
451-645: The Vanderkloof Dam . From the border of Lesotho to below the Vanderkloof Dam, the river bed is deeply incised. Further downstream, the land is flatter, and the river is used extensively for irrigation. At the western point of the Free State, southwest of Kimberley , the Orange meets with its main tributary, the Vaal River , which forms much of the northern border of the province. From here,

#1732791075227492-528: The sluices of the dams being open, a canoeist (or rafter) can easily travel 30 kilometres (19 mi) per day. The lower reaches of the river are most popular, because of the spectacular topography. Commercial tours are available, and these expeditions depart from the border town of Vioolsdrif . The Orange River has no large animals. It lies outside the range of the Nile crocodile , and although hippopotami were once abundant, they were hunted to extermination in
533-493: The 19th century. The Orange River has a relative paucity of species diversity. Surveys from 1995 to 2001 in the Lower Orange River found 19 different fish species from eight different families. The two non-native species recorded in the surveys were Cyprinus carpio and Oreochromis mossambicus , the latter of which had increased rapidly in abundance since the early 1980s. Another exotic species, rainbow trout ,
574-526: The Gariep Dam and the Vanderkloof Dam. The hydroelectric power station at the Vanderkloof Dam was the first power-generation station in South Africa situated entirely underground. The towns Oviston and Oranjekrag were established to facilitate the construction and operation of the new infrastructure. Irrigation in the vast area downstream of the Vanderkloof Dam, which has turned thousands of hectares of arid veld into highly productive agricultural land,
615-844: The Maloti-Drakensberg Mountains. The Golden Gate Highlands National Park includes parts of the northeastern end of the Maloti Range. Other parks in this high mountain area are the Sehlabathebe National Park in Lesotho and the uKhahlamba / Drakensberg Park spanning parts of both KwaZulu-Natal province and Lesotho. These parks are part of the Maloti-Drakensberg Transfrontier Conservation Area . Senqu River Quthing , The Orange River (from Afrikaans / Dutch : Oranjerivier )
656-534: The Orange River have grown in importance. Irrigation in the Eastern Cape has also received a tremendous boost, not only from the additional water being made available, but also owing to improvement in water quality. Without this improvement, the citrus farmers along the Lower Sundays River would almost certainly have continued to suffer losses of productivity. The Lesotho Highlands Water Project
697-638: The Orange River inside Lesotho is known as the Senqu . Parts of the Senqu River freeze in winter because of the high altitude. This creates droughts downstream, which mainly affect goat and cattle production. The Orange River then runs westward through South Africa, forming the south-western boundary of the Free State province . In this section, the river flows first into the Gariep Dam and later into
738-530: The Orange, where the river descends 122 m (400 ft) in a course of 26 km (16 mi). The Orange empties into the Atlantic Ocean between the small towns of Oranjemund (meaning "Orange mouth ") in Namibia and Alexander Bay in South Africa, about equidistant between Walvis Bay and Cape Town . Some 33 km (21 mi) from its mouth, it is obstructed by rapids and sand bars and
779-477: The Orange. Today, several commercial diamond mines operate along the final stretch of the Orange River and around its mouth. Because of the lack of dangerous animals and high water levels during summer, the river is used for recreational canoeing and rafting . Orange River rafting has become very popular with many companies using their camps along the river from which to operate. The most popular trips are four-day and six-day river trips that take place either along
820-684: The South African economy by providing water for irrigation and hydroelectric power . The river was named the Orange River in honour of the Dutch ruling family, the House of Orange , by the Dutch explorer Robert Jacob Gordon . Other names include simply the word for river, in Khoekhoegowab orthography written as !Garib , which is rendered in Afrikaans as Gariep River with the intrusion of
861-666: The Tugela River-Vaal River pumped storage scheme , which used the Sterkfontein Dam , located near Harrismith in the Free State. In 1867, the first diamond discovered in South Africa, the Eureka Diamond , was found near Hopetown on the Orange River. Two years later, a much larger diamond known as the Star of South Africa was found in the same area, causing a diamond rush. This was soon eclipsed by

The park contains habitats supporting a range of Afro-Alpine and Sub-Alpine plants, mammals, birds, reptiles, amphibians and fish. The site hosts 23 percent of the plant species in the whole Maluti Drakensberg area. Some of the park's species are endangered, including three vertebrates: the Maluti redfin , a critically endangered fish which
943-413: The color of its tributary, the Vaal River , which name is derived from the name ǀHaiǃarib "pale river" ( vaal being Afrikaans for pale or grey). Since the end of apartheid , the name "Gariep" has had greater favour in official correspondence in South Africa, although the name "Orange" has greater international recognition. In Lesotho, where the river rises, it is known as the Senqu River, derived from

Today, several commercial diamond mines operate on the last stretch of the river, as well as the beaches around its mouth. Diamond mines also operate on the middle stretch of the river. During the temperate months of March and April, given good rains and
1066-563: The dominant culture. Like much of Lesotho, this bioregion is significantly rural and with limited commercial activity. South Africa has established and diversified the economy of the area, using it for agriculture and tourism . The topography in the South African portion makes it more accessible and useful for livestock farming, crop production and tourism. Temperature extremes in winter and summer also cause seasonal limitations. The mountain range also contains both of southern Africa's only ski resorts, Tiffindell Ski Resort and Afriski . In
1107-608: The early 1980s, officials from Lesotho approached the Ezemvelo KZN Wildlife (previously known as the Natal Parks Board) to propose the collaborative management of the bioregion to protect its natural and cultural heritage. This eventually led to the signing of the Giant's Castle Declaration in 1997. Since then the two countries have been making a concerted effort towards the protection and sustainable use of
1148-735: The gorge below the Augrabies Falls or along the Richtersveld area. The Orange River Project (ORP) was one of the largest and most imaginative projects of its kind in South Africa. It was constructed by Hendrik Verwoerd 's government at the height of the apartheid era. The ORP was built to exploit the waters of the Orange River—which, without the Vaal River, represents some 14.1% of the total runoff in South Africa—and in
1189-518: The highest mountain in the Free State, is also part of the Maloti Range. The mountains form a continuous upland area of rounded peaks with incised deep valleys on the flanks which drain into the Senqu River. Snow and frost may be found even in summer on the highest peaks. The bioregion is made up of sandstone and shale overlain by basalt . The mountain's rough terrain makes it less accessible to visitors and prevented any significant exploitation of its mineral resources. The topography differs between
1230-479: The land area of South Africa (1,221,037 km (471,445 sq mi)). Around 366,000 km (141,000 sq mi) (38%), however, are situated outside the country in Lesotho, Botswana, and Namibia. Some of the earliest precolonial inhabitants called the river ǂNūǃarib , referring to its black colour, or sometimes just Kai !Arib ("Great River"), from which is derived the Afrikaans version Gariep , and translation "Groote Rivier". The early Dutch name for
1271-563: The last 800 km (500 mi) of its course, the Orange receives many intermittent streams (such as the Fish River ), and several large wadis lead into it. In this section, the Namib Desert terminates on the north bank of the river, so under normal circumstances, the volume of water added by these tributaries is negligible. Here, the bed of the river is once again deeply incised. The Augrabies Falls are located on this section of

From here, the water is supplied in two directions, westward along the Orange River (via hydroelectric power generators) to the Vanderkloof Dam and southward through the Orange-Fish Tunnel to the Eastern Cape. Eskom operates hydroelectric power stations at both
1435-538: The rainfall is less than 50 mm (2.0 in) per year. The factors that support evaporation, though, tend to increase in a westerly direction. In the wet season (summer), the Orange river becomes a brown coloured torrent. The huge mass of sediment carried constitutes a long-term threat to engineering projects on the river. The total catchment of the Orange River (including the Vaal) extends over 973,000 km (376,000 sq mi), i.e. equivalent to about 77% of
1476-512: The river flows further westward through the arid wilderness of the southern Kalahari region and Namaqualand in the Northern Cape province to meet with Namibia at 20°E longitude. From here, it flows westward for 550 km (340 mi), forming the international border between the province and Namibia's ǁKaras Region . On the border, the river passes the town of Vioolsdrif , the main border post between South Africa and Namibia. In
1517-510: The river was just that translation, Groote Rivier, meaning "Great River". The river was named the Orange River by Colonel Robert Gordon , commander of the United East India Company (VOC) garrison at Cape Town, on a trip to the interior in 1779. Gordon named the river in honor of William V of Orange . A popular but incorrect belief is that the river was named after the supposedly orange color of its water, as opposed to
1558-563: The two countries. In Lesotho, the mountain range is made up of a continuous landscape of more rounded mountains with deep valleys that drain into Lesotho's Senqu River , known as the Orange River in South Africa. In South Africa, sheer basalt cliffs drop off from the transfrontier into foothills composed of sandstone. This rock is incised by the rivers that flow eastwards. The area is usually dry between May and September, which are largely winter months. It experiences snow every month of
1599-552: The year. The snow and drainage, which includes the Orange River , Tugela River and the tributaries of the Caledon River make this the source of much of Southern Africa's fresh water. The sources of two of the principal rivers in South Africa , the Orange River , known as Senqu in Lesotho, and the Tugela River , are in these mountains. Tributaries of the Caledon River , known as Mohokare in Lesotho, which forms
1640-850: Was conceived to supplement the water supply in the Vaal River System. Water is delivered to South Africa by means of the delivery tunnel which passes under the Lesotho South Africa border at the Caledon River , and then under the Little Caledon River south of Clarens in the Free State, and discharges into the Ash River about 30 kilometres (19 mi) further to the north. The scheme became viable when water demands in Gauteng reached levels that could no longer be supported economically by alternative schemes such as
1681-512: Was made possible by the construction of the Gariep and Vanderkloof Dams. Old established irrigation schemes such as those at Buchuberg , Upington , Kakamas , and Vioolsdrif have also benefitted because regulation of the flow is now possible. On the Namibian side of the river, Aussenkehr produces grapes with the help of water from the Orange. In recent years, the wine-producing areas along
