Lake Bogoria which lies in Kenya’s Great Rift Valley, just north of the equator can be accessed from a diversion on the Nakuru – Baringo Road. The lake is at the beginning of Kenya’s great Northern Wilderness. It is the heart of an arid landscape, in the shadow of the dramatic walls of the Siracho Range. The 32 km2 lake is still volcanically active, and the Western shore is lined with spouting geysers, spurting steam and bubbling geothermal pools. Fresh water springs at the lake edge attract an abundance of birds and wildlife.
The lake has significant ornithological interest with 135 species of birds recorded. Up to two million birds can be found there at any one time, many living in the reserve for months at a time. The soda waters (saline, alkaline) of the lake grow blue-green algae attract one of the world’s largest populations of lesser flamingos and the lake is often carpeted with pink because of the flamingoes. There are many Fish Eagles, which often prey on the local flamingos. Other birds include; little grebe, tawny eagle, pratincole, swift, little bee-eater, cape wigeon, yellow-billed stork, African spoonbill, augur buzzard, gabar goshawk, water dikkop, gret tit, starling, hornbill and crombec.
The surrounding bushed grasslands are home to a number of animals. The Reserve’s herd of the rare Greater Kudu antelope makes it unique and other game includes: buffalo, zebra, cheetah, baboon, warthog, caracal, spotted hyena, impala, gazelle, dik dik and many small mammals. The south shore has acacia-ficus woodland and to the north is a papyrus swamp.
Lake Bogoria has been a National Reserve since 1973 and was designated a Ramsar site in 2001 making it an internationally important wetland area, supporting many regionally and nationally endangered species. These include the migratory lesser flamingo, the greater flamingo and the black-necked grebe.
The lake is recharged by spring-fed and seasonal rivers. These are critical water sources for people and animals. The major source of fresh water is the Waseges River. Lake Bogoria has no outlet.
