Salisbury was established on marshy area. As the settlement grew a series of reservoir were constructed beginning with Cleveland dam (910 ML) in 1913. Watershed area is about 2 227 km2 ranging in altitude between 1300 m and 1500 m. Mean annual precipitation range 750 mm to 900 mm. Mean maximum and minimum temperatures are 10.6OC 29.9OC Harare City sits on the wetland headwaters of its water supply. The city is 98 300 ha, of which 21,750 ha (22%) is wetlands Records of the Manyame River flow into lake Chivero indicate a decreasing annual inflow. Although since 1939 successive governments have outlawed developments on wetlands, wetlands loss in urban areas occurs at significant rates due to the government\u2019s reluctance to enforce the various legal instruments protect wetlands for fear of losing political support. Sediment studies show that the lake has lost 20% water storage capacity Concurrently, the Municipality\u2019s capacity for waste treatment has deteriorated, resulting in discharge of inadequately treated sewage into Lake Chivero. The fine mud sediments now store sufficient phosphorus to sustain hypereutrophic state for several years after rehabilitation of the sewage works.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">View the author&#8217;s explanation<\/h2>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-vimeo wp-block-embed-vimeo wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"0087.Magadza.oral.mp4\" src=\"https:\/\/player.vimeo.com\/video\/637945728?h=ae01970ad3&amp;dnt=1&amp;app_id=122963\" width=\"1200\" height=\"675\" frameborder=\"0\" allow=\"autoplay; fullscreen; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Author(s):\u00a0Christopher H.
