Kenya’s Purest Springs-Mzima springs


Mzima Springs are a series of four natural springs in Tsavo National Park, Kenya. They are located in the west of the Park, around 48km from Mtito Andei. The source of the springs is a natural reservoir under the Chyulu Hills to the north.

Mzima. The word means “alive.” Yet the life of Kenya’s Mzima Springs is largely born of ash and dung.The Chyulu range is composed of volcanic lava rock and ash, which is too porous to allow rivers to flow. Instead, rain water percolates through the rock, and may spend 25 years underground before emerging 50 kilometres away at Mzima. Filtered over many years, the pure water gushes forth at a steady pace of more than 50 million gallons (190 million liters) a day, creating an oasis at the heart of Kenya’s Tsavo West National Park that gives rise to Mzima’s famously clear stream, which flows through a series of pools and rapids. Two kilometres downstream from the springs, the stream is blocked by a solidified lava flow and disappears below the surface again.

In the neighboring Chyulu Range stand porous peaks of volcanic ash, whose youngest cones formed about 500 years ago. Rising 7,000 feet (2,000 meters) above an arid plain, these hills trap up to three feet (one meter) of rain each year from moisture-laden winds. All that rain soaks into the sponge-like ash and percolates down until it hits impervious bedrock and begins its underground journey to Mzima Springs some 25 miles (40 kilometers) away.

Mzima springs

Mzima is one of Tsavo’s most popular wildlife attractions owing to its resident populations of hippos and Nile crocodiles. Mzima’s isolation makes both species  dependent on its waters: other sources are too distant for them to reach by overland travel. The hippos also sustain an entire food chain. They browse the surrounding savannah by night and return to Mzima’s pools by day, where their dung fertilises the water. Fruiting trees such as date and raffia palms, waterberrys and figs grow beside the water, using their submerged roots to absorb nutrients. Their fruits are a source of food for vervet monkeys and a variety of birds. Below the water’s surface, the invertebrates which feed on the hippo dung are preyed on by fish and cormorants.

The springs were made famous by wildlife film-makers Alan and Joan Root’s 1969 nature documentary Mzima: Portrait of a Spring, which featured underwater footage of the hippos and crocodiles. They were also the subject of the Survival Special Mzima: Haunt of the Riverhorse in 2003, which featured the first footage of a hippo infanticide.
