Site description This reservoir was completed in 1965 by damming the Pangani river downstream of the confluence of the Ruvu and Kikuletwa rivers. The latter rises on Mount Meru to the north-west, collecting streams from Mount Kilimanjaro on its way. The Ruvu flows from Lake Jipe to the north-east and collects water from Mount Kilimanjaro and the Pare mountains. The surrounding habitat is dry CommiphoraAcacia woodland that slopes gently into the water. The lake is an important fishery and virtually the whole shoreline is utilized by fisherman who have established permanent settlements a few hundred metres from the water’s edge. The resultant shoreline is short grassland that becomes heavily overgrazed during the dry season. The northern shore, between the two rivers, is a seasonal swamp of considerable size, covering some 40 km² during the wet season. This swamp grades into an extensive woodland of mature Acacia xanthophloea that may hold an important heronry.
