Nyami Nyami

Also Known As: also Nyaminyami; the Zambezi River God, the Zambezi Snake Spirit
Region/Culture: Southern Africa
Mythos: African Mythology
Primary Type/Nature: Gods and Deities
Mythical Attributes: He owns and controls the life of the Zambezi, sending or withholding fish and floodwater, and he fed the valley from his own body during famine.
Role in Mythos: He is the resident spirit of the river at Kariba Gorge among the Tonga of the middle Zambezi, a local power of a particular stretch of water rather than a god of a whole people.
Relation to Humans: Those who lived on the river approached him through elders and spirit mediums, and travellers soothed him before crossing the water where his rock stood. He was understood as a provider first and a danger second, though the same current that fed the valley also drowned people in it.

Before the lake there was a rock. It sat in the narrowest part of the gorge where the Zambezi squeezed between walls of hot stone, and the water came around it and turned, folding in on itself in a slow grey spiral. The Tonga called the place kariva, a trap, and the name stuck to the whole valley and then to the dam and then to the lake. Canoes that drifted too near the rock went down. Nothing came up. That whirlpool had an owner, and the people who fished the river knew better than to cross it without settling their account with him first.

Nyami Nyami is usually drawn as a serpent with the head of a fish, a body thick as a man is tall and a length nobody has ever measured because nobody has ever seen the end of it. That image is now stamped into ten thousand carved walking sticks and soapstone pendants sold along the lakeshore, which has done something to it. The older descriptions are looser and stranger. He is a snake. He is a fish. He is the coil of the current itself, which is not really a description of an animal at all, and the vagueness may be closer to the truth of the thing than the tidy curio silhouette.

His name is the most concrete evidence anyone has about him. Nyama means meat. The name is generally read as a doubling of it, and one gloss traces it to a phrase meaning pieces of meat. The story attached to it is the best thing in his record. In the years when the rain failed and the millet did not come, the god would lie in the shallows and let the people cut strips of flesh from his back. However much they took, the wound closed and the body was whole again in the morning. A woman going down to the water with a knife in a drought year, wading out to a great warm bulk lying half submerged in the shallows, cutting what her family needed and walking back up the bank, is not an image of a monster. It is an image of a larder.

He was never a national god, and this matters more than most accounts of him admit. Tonga religion, as Elizabeth Colson and Thayer Scudder recorded it across sixty years of work in the Gwembe Valley, runs on the basangu, the local spirits of place who answer for rain and crops and sickness, with a remote creator called Leza somewhere above them all. There are no temples in it, no national shrines, and no single body of myth that every Tonga person holds. Nyaminyami fits that pattern exactly. He is the spirit of one reach of one river. Joshua Matanzima, working among Tonga and Shangwe speakers around the gorge in 2017, found that belief in him was strongest in the Mola and Musampakaruma chiefdoms and thin or absent elsewhere, and argued that the whole complex was carried into the valley from outside rather than grown in it. Colson and Scudder had suspected as much decades earlier.

Then the engineers came. In 1956 the governments of Northern and Southern Rhodesia began damming the gorge at the trap rock, and elders on both banks said what would happen: the god lived upstream with his wife, the wall would stand between them, and he would take the wall apart. In 1957 the worst flood on record tore through the works. In 1958 a worse one followed, on a scale the hydrologists had rated at once in a thousand years, and it destroyed the coffer dam, the access bridge and part of the wall. Italian and local workers drowned. Some of the bodies were never recovered, and are said to be in the concrete still.

When the missing men could not be found, the search party finally did what the elders had been telling them to do. A black calf was killed and floated out on the river at dusk. By morning the calf was gone, which in that water explains itself, and the bodies of the workers were lying where it had been, which does not.

The dam was finished anyway. The generators came on in 1960. Fifty seven thousand Tonga were moved off the land the lake was about to cover, and the moving was not gentle: at Chisamu, in Chief Chipepo’s country, people refused to go, sounded the budima war drums for the first time since 1898 and came at the encampment with spears, and on 10 September 1958 the colonial police fired on them and killed eight. Between 1958 and 1964 a rescue operation lifted around six thousand animals off the drowning hills and carried them to high ground. The animals got boats and a press campaign. The people had been moved first and with considerably less ceremony.

The god did not stop the dam.

What happened next is the part the souvenir stalls leave out. A settler journalist named Frank Clements published Kariba: The Struggle with the River God in 1959, which put the fish-headed serpent on the cover of the whole enterprise and framed the engineering as a duel with African superstition. The image travelled. Later scholarship, David McDermott Hughes on how white Rhodesians made a landscape out of the new lake and Matanzima on the stereotyping and appropriation of the belief between the 1860s and the 1960s, has traced how thoroughly the river god was taken up and reused by people who did not believe in him. The Tonga picked him up too, and rallied behind him as a figure of refusal while they were being cleared off the valley floor. He was a local water spirit before all of this. He came out of it as an emblem.

His powers are the powers of a river and no wider. He grants or withholds fish, raises the flood, drags the careless under at the trap rock, and in the hardest years feeds the valley from his own flesh. His weakness is the same fact stated the other way. He is bound to a stretch of water, answerable only to the people who live on it, and his authority ends where the gorge ends. He could break a coffer dam twice and not break the second attempt. The tremors that still run through the ground around the lake are real enough, caused by the mass of stored water pressing on the crust and rising and falling with the level. Along the shore they are read as a husband on the wrong side of a wall, still trying to get back.

Frequently Asked Questions

Who is Nyami Nyami?

Nyami Nyami is the river god of the Zambezi, revered by Tonga communities living around the Kariba Gorge in what is now Zimbabwe and Zambia. He is understood to control the life of the river, providing fish and floodwater, and he is credited with feeding the valley from his own body during famine.

What does Nyami Nyami look like?

Nyami Nyami is most commonly depicted with the long body of a snake and the head of a fish, an image now mass produced on carved walking sticks and pendants sold around Lake Kariba. Older accounts are less fixed, describing him as a snake, as a fish, or simply as the whirlpool that once turned around a rock in the gorge.

Did Nyami Nyami cause the Kariba Dam floods?

Tonga elders warned that damming the gorge would enrage the river god by cutting him off from his wife upstream, and when catastrophic floods destroyed parts of the works in 1957 and again in 1958, killing Italian and local workers, the disasters were attributed to him. The dam was completed regardless and its generators came on in 1960.

Why is Nyami Nyami associated with earth tremors at Lake Kariba?

People along the lake explain the frequent small earthquakes there as Nyami Nyami trying to force his way back to his wife on the other side of the dam wall. The tremors themselves are caused by the enormous weight of stored water pressing on the earth’s crust, and they intensify as the lake level changes.

Was Nyami Nyami worshipped by all Tonga people?

No. Research in the Gwembe Valley by Elizabeth Colson, Thayer Scudder and later Joshua Matanzima found that belief in Nyaminyami was concentrated in chiefdoms close to the Kariba Gorge, particularly Mola and Musampakaruma, rather than being universal across Tonga country. Tonga religion generally centres on local spirits called basangu and a distant creator, Leza.
