GORDON when he discovered the Orange River at "De Fraaye Schoot" near the present Bethulie, probably on the 23rd December 1777. I. INTRODUCTION When the government of the Republic of South Africa in the early sixties decided to initiate a comprehensive water development scheme of its largest single water resource, the Orange River, this gave rise to a wide range of basic and applied scientific sur­ veys of that area. The reasons for these surveys were threefold: (1) The huge capital investment on such a water scheme can only be justified economically on a long term basis. Basic to this is that the waterworks be protected, over a long period of time, against inefficiency caused by for example silting. Therefore, management reports of the catchment area should.be produced. (2) In order to enable effective long term planning of the management and use of the natural resources in the area it is necessary to know the state of the local ecosystems before a major change is instituted.

  • Orange River Project
    ORANGE RIVER PROJECT: OvERVIEW South Africa NAMIBIA BOTSWANA Orange-Senqu River Basin Vanderkloof Dam LESOTHO Gariep Dam LOCATION SOUTH AFRICA The Orange River Project (ORP) is the largest scheme in the Orange–Senqu River basin, and includes the two largest dams in South Africa, the Gariep and Vanderkloof. They regulate flows to the Orange River and increase assurance of supply. DESCRIPTION Gariep and Vanderkloof dams were constructed as part of the project, and have a combined storage of 8,500 million m3. The ORP includes several sub-systems. The Orange–Riet Water Scheme.* The Orange–Fish Transfer Tunnel.* The Orange–Vaal Transfer Scheme.* Bloem Water: Pipeline network between Gariep Dam and the towns of Trompsburg, Springfontein and Philippolis. Irrigation abstractions: Between Gariep Dam and downstream of Vanderkloof Dam, up to the confluence of the Vaal and Orange rivers (near the town of Marksdrift). Urban and industrial abstractions: Between Gariep Dam and Marksdrift (including Hopetown and Vanderkloof towns). Support to the Lower Orange Water Management Area Schemes: * Support to most of the demands in the Gariep Dam (© Hendrik van den Berg/Panoramio.com) Lower Orange, including irrigation, urban use and power generation. Caledon–Bloemfontein Government Water Scheme.* * Further details are given on separate pages PURPOSE The purpose of this very complex scheme is to supply demands within several sub-systems, including the Upper and Lower Orange water management areas all the way down to the Orange River mouth, and the Eastern Cape Province. These demands include irrigation, urban, industrial and environmental water requirements. Power generation is also part of the system, including at Gariep and Vanderkloof dams, which contributes to the Eskom national power grid.

Along the Witwatersrand and on the coal fields of the Eastern Transvaal and parts of Northern Natal saline discharges from both point and diffuse sources, usually associated with mining and industrial activity, have been largely responsible for these increases in salinity, but mineralization (salinization) from natural non-point sources has also played a deleterious role in rivers draining certain semi-arid catchment areas. Among the latter rivers are the Berg, Breg and Olifants of the Western Cape and the Fish, Sundays, Bushmans and Kowie of the Eastern Cape Province. The significance of the effects of non-point mineralization is illustrated by the serious damage to apricot orchards in the Golden Valley area of the Great Fish River during the sixties and the relatively recent deleterious effects of high chloride concentrations on citrus crops in the Klrkwood area of the Sundays River.
