Site description Lake Langano is in East Shewa Zone. It is one of a group of lakes in the middle of the Ethiopian Great Rift Valley, about 55 km south of Zeway. The main source of water, via several small rivers, is from the Arsi mountains (which form the eastern wall of the Great Rift Valley). Water flows from the lake via the Horo Kelo river into nearby Lake Abijatta (within Abijatta–Shalla Lakes National Park, site ET048). The lake is 23 km long, has a maximum width of 16 km, and is up to 46 m deep. There are two islands, one with hot springs, and both visited regularly by people. The lake is alkaline. Seasonal variation in the water-level is less than 1 m. Much of the shore comprises rocky or pebble beaches (devoid of vegetation), particularly on the eastern side, with a number of swampy bays in the north and south. The sandy beaches frequented by visitors are mostly on the western shore. Sedges and rushes fringe some parts of the lake and cover many of the small swampy bays. Ceratophyllum demersum and Potamogeton spp. are important submerged aquatics. The area between Lakes Langano and Abijatta is naturally open Acacia woodland and bush, but many of the trees have been cut and much of the land cleared for cultivation. The eastern side of the lake, where the streams enter, retains some trees, especially Ficus sp. and small Sesbania sp. On the southern and south-eastern shores there are dense thickets of Acacia, other spiny bushes, climbers and large Ficus vasta and F. sycomorus trees. The surrounding slopes, within Munessa State Forest, are dominated by Podocarpus falcatus. The lake is much used for recreational activities.
