It was formed in 1952 by the Hunyani poort Dam and is situated on the Hunyani River some 37 km southwest of Salisbury* in the Republic of Zimbabwe**. It is a lake of many aspects: being a popular recreational site, the City‘s primary water supply reservoir (and the fourth largest impoundment in Zimbabwe), a source of irrigation water to downstream farms, an important fishery, and, until the 1970s, the receptacle of Salisbury‘s sewage effluent. It is, in short, typical of so many ‘urban‘ lakes in Africa and throughout the world. Lake McIlwaine is also unique, to my knowledge: being amongst the first of the major man-made lakes on the continent to suffer from what is known as cultural eutrophication, and the first to be r:ehabilitated to a mesotrophic state through a rational programme of lake management. This volume synthesizes this process of eutrophication and recovery in terms of the geology and geography (Chapter 2), physics (Chapter 3), chemistry (Chapter 4) and biology (Chapter 5) of the lake, and, whilst discussion | | 出版日期 | Book 1982 | | 关键词 | Eutrophication; benthic; fisheries; limnology; macrophytes; phytoplankton; water quality; zooplankton | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-009-7983-3 | | isbn_softcover | 978-94-009-7985-7 | | isbn_ebook | 978-94-009-7983-3Series ISSN 0077-0639 Series E-ISSN 2215-1729 | | issn_series | 0077-0639 | | copyright | Dr W.
