Albert Falls Dam

Albert Falls Dam is a dam in the Umgeni River, just outside Pietermaritzburg, KwaZulu-Natal, South Africa. Established in 1976, the dam has a gross capacity of 290.1 million cubic meters and a surface area of 23.521 square kilometres (9.082 sq mi). The dam wall is 33 metres (108 ft) high. A lake-wide bloom of the dinoflagellate Ceratium hirundinella, discovered in Albert Falls Dam in October 2006, exposed a significant ecological change indicative of reduced water quality in this historically mesotrophic reservoir. The spatial distribution of the bloom was examined synoptically in October 2006 and in January 2007.

The water is brown and murky.
Barrage d'Albert Falls

Le barrage d'Albert Falls est un barrage situé sur la rivière Umgeni, à environ 20 km au nord de Pietermaritzburg, dans la province du KwaZulu-Natal, en Afrique du Sud. Mis en service en 1976, il est construit principalement pour l'approvisionnement en eau domestique et l'irrigation. Caractéristiques Le barrage est un ouvrage en remblai de terre. Il mesure 33 mètres de hauteur et 2 006 mètres de longueur. Il retient le réservoir d'Albert Falls, dont la capacité totale est d'environ 290 000 000 mètres cubes. La superficie du plan d'eau est proche de 23,5 km2. Le réservoir est utilisé pour l'alimentation en eau domestique, pour l'irrigation et pour des activités de loisirs liées au plan d'eau. Écologie Le réservoir d'Albert Falls fait l'objet de plusieurs études scientifiques portant sur la qualité de l'eau et l'évolution de son écosystème. En 2006, une prolifération importante du dinoflagellé Ceratium hirundinella est observée dans le lac. Selon les travaux de R. C. Hart et P. D. Wragg, cet épisode révèle une dégradation de la qualité de l'eau associée à une augmentation des concentrations de phosphore dans le bassin versant. Les chercheurs constatent aussi des modifications de la structure des communautés zooplanctoniques. Elles concernent en particulier la diminution de certaines espèces de cladocères et des changements dans l'abondance des copépodes. L'apparition et le développement de Ceratium hirundinella sont associés à une baisse du rapport azote/phosphore et à une augmentation des apports en phosphore provenant du bassin de l'Umgeni. Environnement Le barrage se situe dans le bassin hydrographique de l'Umgeni, dans une région caractérisée par des prairies, des zones humides et des formations forestières des Midlands du KwaZulu-Natal. Plusieurs espèces d'oiseaux aquatiques et terrestres fréquentent les abords du réservoir.

Rietvlei Nature Reserve, located in southern Pretoria, is about 4,000 hectares (40 km2) in size, and includes the entirety of the Rietvlei Dam which impounds the Rietvlei River, in Gauteng, South Africa. The reserve is wedged between the R21 highway (OR Tambo Airport highway) on the western side and the R50 (Delmas-Bapsfontein) road on the north-east. The mean elevation above sea level is approximately 1,525 meters, with the highest point at 1,542 m and the lowest at 1,473 m, the dam’s outflow in Sesmylspruit. The reserve covers a surface area of approximately 4,003 ha or 40 km2, of which the dam constitutes some 20ha. A network of roads criss-cross the entire area, which facilitates access to visitors and management. Flora and fauna Trees Both indigenous and exotic species of trees can be found in the reserve. Birds Some 404 species of bird utilize the reserve. Birds commonly encountered include colonies of southern masked-weaver, the invasive common myna and conspicuous pied crow, buffy pipit, blacksmith and crowned lapwing on short or burnt grassland, and Cape longclaw and rufous-naped lark in denser grassland or shrubby areas. Amur falcon and barn swallow occur annually in summer. Black-shouldered kite, spotted thick-knee, cattle egret, helmeted guineafowl, Swainson's spurfowl, African palm-swift, southern red bishop, anteating chat, stone chat, capped wheatear, fork-tailed drongo and pied starling are resident or regularly seen species. Some special or less commonly seen species are Alpine swift in winter, African yellow warbler in shrubs along the flood plain, great crested grebe and maccoa duck at the dams, African cuckoo hawk, Peregrine falcon, red-throated wryneck and orange-breasted waxbill. Mammals The reserve carries around 1,600 individual large mammals. Cheetah, blesbuck, black wildebeest, red hartebeest, eland, common zebra, waterbuck, reedbuck, springbuck, mountain reedbuck, steenbok, grey duiker, oribi, leopard, buffalo, and hippopotamus can all be found in the reserve.

Arderne Gardens

Arderne Gardens is a public park and arboretum in Claremont, Cape Town, located in the Western Cape of South Africa. It was established in 1845 by Ralph Henry Arderne, a timber merchant originally from Cheshire, England. In 1979, the park was named a South African Provincial Heritage Site. It is now a popular venue for wedding photographs. The 4.5-hectare park contains over 300 trees, six of which have been designated as Champion Trees by the Department of Agriculture, Forestry and Fisheries. The Moreton Bay fig near the park entrance is one of the largest trees in the country and is nicknamed the "Wedding Tree" by locals. The ponds in the garden are the source of the Black River which then runs underground beneath Main Road and the railway line before emerging as a canal. The garden is best known for the wide open lawn (sometimes called the "great lawn") surrounding a Norfolk Pine and a Japanese-style koi pond. Unlike nearby Kirstenbosch Botanical Gardens, the focus of the Arderne Gardens is the cultivation of exotic species. History As a timber merchant living in the Cape Colony in the late 1800s, Ralph Henry Arderne (1802-1885) was in the unique position to trade indigenous plant seedlings in exchange for the exotic seedlings, shrubs, and perennial plants carried by ships that had stopped to replenish their supplies. In 1845, he acquired the section of land (part of the old Stellenberg Estate) where he planted a garden, built a home and called it "The Hill". In time, the garden became famous among local residents as a place to stroll and enjoy the outdoors. Henry Mathew Arderne (1834-1914), Ralph's oldest son, took over the garden in the early part of the twentieth century. He continued his father's tradition of trading local seedlings for exotic plants until his death in 1914. That same year, the Arderne property was purchased by Mr. G. Wilks. He proceeded to divide the land into building lots and demolished The Hill. In 1928, Mr. A. W. van den Houten, the Director of Parks and Gardens in the Cape Town Municipality, persuaded City Council to buy a 4.5-hectare section of the garden stretching from Main Road to the site where the Arderne's house once stood. In 1961, this section of land was officially named the Arderne Gardens. Mr. A. M. J. Scheltens was the curator of the Arderne Gardens for the following 27 years. In the early 2000s, the Arderne Gardens fell into a state of neglect. In 2004, the non-profit organisation the Friends of the Arderne Gardens was formed to assist the City of Cape Town with protecting, preserving, and promoting public awareness of the garden.

Gouda Wind Facility

Gouda Wind Farm is a wind farm just outside the town of Gouda in the Western Cape province of South Africa that at 138 MW is one of the largest wind-farms in Southern Africa. The project cost R2.7 billion (US$199 million) and was brought online in early September 2015. At the time of its completion it was the largest wind-farm in the Western Cape. It is capable of powering 200,000 households per year or 400-gigawatt hours of electricity. It is estimated that power generated from Gouda Wind Farm will avoid the emission of 406 million metric tons of CO2 per year of equivalent power produced from a coal-fired power plant. It is owned in partnership between the South African renewable energy and engineering firm Aveng and Spanish renewable energy company Acciona Energia. It is located along the R44 34 km from the town of Porterville or 115 km north east of Cape Town, just outside of Gouda. Design The wind farm is unusual in that it was the first wind-farm in South Africa to have concrete towers instead of the more usual steel towers. It was decided to use concrete as they could be produced domestically unlike steel towers which needed to be imported. Each of the turbines three blades are 50 meters in length with the pitch of the blades designed to maintain rotation speed as wind speed drops by increasing; they are designed to shut down if wind speeds exceed 70 km/h. They are mounted on 100m high concrete towers. The turbines are required to be designed so as not to exceed 35 decibels of sound. See also List of wind farms in South Africa References
Harold Johnson Nature Reserve

The Harold Johnson Nature Reserve is a small nature reserve (100 hectares (250 acres)) on the KwaZulu-Natal north coast. The reserve is administered by Ezemvelo KZN Wildlife and is on the southern bank of the Tugela River and 6 kilometres (3.7 mi) from the river's mouth. Wildlife species include zebra, bushbuck, impala, blue, red duiker and grey duiker, vervet monkey, slender mongoose, white-tailed mongoose, banded mongoose and porcupine. Over 190 bird species have been observed in the reserve. One hundred and fourteen butterflies species have been recorded. Two national monuments are located within the boundaries: Fort Pearson and the Ultimatum Tree. In 1879 the British presented an ultimatum to the Zulu nation at the Ultimatum Tree on the banks of the Tugela River; this ultimatum precipitated the Anglo Zulu War.

Owendale, South Africa

Owendale is a town in Kgatelopele Local Municipality in the Northern Cape province of South Africa. It is located between Postmasburg and Daniëlskuil. An old mining town, it was owned by Pieter du Toit from 1998 to 2006, when it was auctioned. He had reportedly bought the settlement as a base for Gemeente van die Verbondsvolk, a religious cult. Members of the congregation wished to live in an isolated village, but the dearth of available jobs led to the disintegration of the community. Asbestos mining operations had ceased in 1993. Louis Theroux visited the town as part of his 2000 Weird Weekends documentary series, in which the town is described as being for "whites only". See also Morgenzon Balmoral, Mpumalanga References
Redstone Solar Thermal Power

Redstone Solar Thermal Power (RSTP) is a solar power tower with molten salt energy storage, located in Postmasburg, near Kimberley, in the Northern Cape Region of South Africa. Redstone will have a capacity of 100 megawatts (MW) to deliver power to 200,000 people and was awarded in bid window 3.5 of the REIPPP at a strike price of 122.3 ZAR/KWh including time of day pricing in 2015. The project was initially based on the technology of now bankrupt Solar Reserve, but was delayed for several years because the PPA was not signed by Eskom until 2018. After the project was revived, the plant was put under construction, until May 2025 when it was connected to the grid for the first time after 4 years of construction. The technology is provided by Brightsource and John Cockerill, as demonstrated in the Noor Energy 1 project in the UAE. Announcement in 2015 In January 2015, the South Africa Department of Energy awarded the RSTP project to a consortium led by SolarReserve and the Arabian Company for Water and Power Development (ACWA Power). The project was to achieve financial close at end of 2015 and commence operations in early 2018. Overall project cost were estimated at $715 million, and basic power tariff offered at $124/MW·h. Peak power tariff is 270% of the basic power tariff i.e. $334/MW·h. Tariffs quoted in Rands, fully indexed, were R1.70/kWh base rate and R4.58/kWh peak rate (2015 rate). The RSTP project would create 800 direct jobs during construction, with a planned 30-year operating life. Technology The RSTP project features a 2-tank direct molten salt energy storage with 12 hours of full-load energy storage, namely 1200 MW·h of equivalent power production, avoiding any backup fuel requirement. The RSTP project is located adjacent the 75 MW Lesedi and 96 MW Jasper photovoltaic solar power projects. Together the three projects comprise a combined CSP and PV solar park with a total 271 MW of generating capacity. Delay since 2016 In early 2016, the power purchase agreement (PPA) worth R50 billion with Eskom was postponed because of a generation surplus. In April 2018, the purchase power agreement (PPA) with Eskom was signed. In August 2019, it was reported that financing for Redstone was complete. It is unclear what the bankruptcy of technology provider SolarReserve in 2020 means for the project. On 10 May 2021 ACWA Power announced the achievement of financial close, with commercial operations expected to commence in Q4 2023. ACWA Power appointed Chinese company SEPCO3 to finish construction on the project. The facility's tower was eventually completed in 2024, reaching a height of 248 meters. However, not all of the planned 40,000 heliostats surrounding the tower had been constructed at this point. Synchronization onto the national grid was then expected to take place in September 2024.

Rondebosch Library

Rondebosch Library is a public library in Rondebosch, Cape Town, South Africa. It was ranked 18th in the City of Cape Town's top circulating libraries in 2013. The library's holdings can be searched online via the City of Cape Town's Open Public Access Catalogue (OPAC). Rondebosch Town Hall The library is housed in the former Rondebosch Town Hall. The main library is situated in the hall itself, which is no longer used for public meetings, as well as on the stage and in two side rooms, while the children's section is housed upstairs and on the balcony. The building was designed by George Murray Alexander and completed in 1899. In addition to a large public hall with a roof over 10m high, a stage and balcony, the building was designed to hold municipal offices, a public library and refreshment rooms. The building is made of rough stone, which has been painted a dull beige, and has high teak doorways and a teak staircase. A stained glass window above the doors onto the portico balcony depicts the Rondebosch municipal crest, and a view of Devil's Peak and the Rondebosch area. The original portico over the front doors became unsafe and was demolished, and rebuilt after 1969. Renovations In July 2018, Rondebosch Library was closed to the public due to required renovations of the roof and library infrastructure. The Library re-opened its doors to the public on Wednesday, 28 July 2021.
