Lake Logipi is a saline, alkaline lake that lies at the northern end of the arid Suguta Valley in the northern Kenya Rift. It is separated from Lake Turkana by the Barrier volcanic complex, a group of young volcanoes that last erupted during the late 19th century or early 20th century. Saline hot springs discharge on the northern shoreline of Lake Logipi and at Cathedral Rocks near its southern limit, and help to maintain water at times of extreme aridity. During the rainy season, the lake is also recharged from the Suguta River which flows northward along the Suguta Valley, periodically forming a temporary lake (Lake Alablab) that unites with Logipi.

Lake Logipi has a maximum depth of 3 to 5 m, and is about 6 km wide by 3 km long. Its waters are of sodium bicarbonate composition with a pH of 9.5-10.5 and salinity (total dissolved salts) that varies from less than 20 g/L to greater than 50 g/L. Efflorescent salt crusts (trona) are present around its margins. Flamingoes frequently inhabit the saline waters feeding on cyanobacteria (Arthrospira spp. - formerly termed Spirulina) and other plankton.[1][2]
Lake Turkana extended after extreme rainfalls in 2020 and overflowed Lake Logipi.[3]

Le lac Logipi est un lac de soude, salé situé à l'extrémité nord de la vallée de la Suguta, dans le nord du Kenya. Il est séparé du lac Turkana par un complexe volcanique, un groupe de volcans récents entré plusieurs fois en éruption à la fin du XIXe et au début du XXe siècle. Des sources d'eau chaude et salée s'écoulent dans le lac sur sa rive nord et aux environs de Cathedral Rocks, près de son extrémité méridionale, ce qui permet de maintenir un minimum de niveau d'eau en période d'extrême aridité. Durant la saison humide, le lac est alimenté par la rivière Suguta, un cours d'eau non-permanent qui coule vers le nord le long de la vallée de la Suguta, et qui forme saisonnièrement un lac temporaire, le lac Alablab, qui rejoint le Logipi.Другой контент может иметь иную лицензию.
