During World War I, retreating German forces dumped weapons, supplies, and possibly a sealed safe of gold into the lake to keep it from enemy hands.
The lake’s dark waters and unusual depth have fueled both curiosity and superstition. Some claim it is bottomless, while others point to discoveries of wartime relics as proof that more may still be hidden below.
Lake Otjikoto’s role in Namibia’s history and the challenges of diving there make it a rare and intriguing site for explorers.
Television host Josh Gates brought global attention to the lake in the Expedition Unknown episode “Africa’s Cursed Lake of Gold”. He joined divers in search of the rumored treasure.
Their journey highlighted both the dangers of deep-water exploration and the enduring pull of a mystery that has survived for generations.
The Legend of Africa’s Cursed Lake of Gold
Lake Otjikoto in Namibia is known for its deep, clear waters and its connection to a hidden cache of gold from World War I. Stories about the lake mix documented history with long-standing local beliefs.
Origins of the Curse
The legend began during World War I when Namibia was under German colonial rule. In 1915, German forces retreated from advancing South African troops.
To prevent capture, they dumped weapons, ammunition, and gold into Lake Otjikoto. Many locals believed the gold carried a curse.
Some said those who tried to recover it would meet misfortune. This belief may have grown from real accidents during early diving attempts.
Historical records show the Germans used the lake as a dumping site for military equipment. However, no one has proven the existence of a large gold hoard.
Wartime secrecy and dangerous diving conditions helped the curse story endure for more than a century.
Local Myths and Folklore
For the local Oshiwambo people, Lake Otjikoto has long been a sacred site. Oral traditions describe it as a place where spirits dwell, and disturbing its waters could bring harm.
Some myths describe the lake as bottomless, an idea fueled by its unusual depth and dark waters. Modern measurements show it is not bottomless, but its depth of over 100 meters still inspires caution.
Folklore blends with historical events. The German gold story became part of these tales, with some versions claiming the treasure is guarded by spirits of fallen soldiers.
Such beliefs continue to shape how the community views outsiders who come to search the lake.
Impact on Namibian Culture
The legend of the lake has become part of Namibia’s cultural identity. It attracts historians, divers, and travelers who are drawn by the mix of history and mystery.
Local tourism in the Otjikoto area benefits from this interest. Museums in nearby Tsumeb display recovered weapons and artifacts, offering context to visitors.
The story appears in media, such as the Travel Channel’s Expedition Unknown, which documented dives in search of the treasure.
For Namibians, the tale is both a reminder of colonial history and a living piece of folklore.
Otjikoto Lake: Namibia’s Mysterious Depths
Otjikoto Lake in northern Namibia is one of only two permanent natural lakes in the country. Its deep, emerald waters hide unique geological origins and a trove of historical artifacts from the early 20th century.
The lake also supports rare aquatic life found nowhere else in Namibia.
Geological Formation and Features
Otjikoto Lake formed when the roof of a limestone cave collapsed, creating a sinkhole filled by groundwater. This type of depression is common in karst landscapes, but Otjikoto is unusual for retaining water year-round in an otherwise arid region.
The lake measures about 102 meters in diameter and reaches depths of at least 55 meters. Some reports suggest it could be deeper.
Its name comes from the Herero word for “deep hole,” a fitting description of its steep, rocky sides.
Located only 20 kilometers northwest of Tsumeb and just 100 meters from the B1 national road, visitors can easily access it. The water’s greenish hue comes from dissolved minerals and algae growth, which also reduce underwater visibility for divers.
Historical Significance
During World War I, retreating German forces in Namibia (then German South West Africa) dumped weapons, ammunition, and other military supplies into the lake to prevent their capture by advancing South African troops.
Much of this material remains underwater today, forming what people often call the Otjikoto Underwater War Museum. Divers have recovered rifles, cannons, and artillery shells, many now displayed at the Tsumeb Museum.
The lake is also linked to local legends of lost gold, earning it the nickname “Lake of Gold”. While no one has recovered a confirmed gold hoard, the story continues to attract treasure hunters and history enthusiasts.
Ecological Insights
Otjikoto Lake is home to fish species adapted to its unique environment. One of the most notable is the Tilapia guinasana, a rare mouth-brooding cichlid found only here and in nearby Lake Guinas.
The lake’s water chemistry and depth create a stable habitat, but its isolation makes the ecosystem vulnerable to disturbance. Conservation efforts aim to protect both the aquatic life and the surrounding vegetation.
Birds, including kingfishers and herons, often visit the shores, taking advantage of the fish-rich waters. The combination of historical artifacts and biodiversity makes Otjikoto important for both cultural heritage and natural science in Namibia.
World War I and the Lost Treasure
During World War I, Namibia—then known as German South West Africa—saw a short but intense military campaign. German forces faced advancing South African troops and made decisions that still spark interest today.
One story tells of valuable items hidden in Lake Otjikoto.
German Troops and the Surrender
In 1915, German colonial troops in Namibia were outnumbered and cut off from supply lines. South African forces, fighting under British command, advanced quickly through the region.
The Germans made their last stand near the town of Tsumeb. Facing defeat, they surrendered to the Union Defence Force.
Before the surrender, soldiers dumped military equipment in Lake Otjikoto. This deep, sinkhole lake was close to their position and offered a quick way to conceal items.
Reports indicate that weapons, ammunition, and possibly valuables were dumped to prevent capture. The surrender ended German control in Namibia and shifted the territory into South African administration under a League of Nations mandate.
The Fabled Gold Safe
One enduring story claims that a heavy safe filled with gold coins was thrown into the lake. The gold was said to be part of the German colonial treasury.
Eyewitness accounts from locals and soldiers fueled the legend. Some say the safe contained payroll funds for the troops, while others believe it held reserves meant for the German administration.
No one has confirmed recovery of such a safe. Divers have searched the depths, but the lake’s steep walls and silt make exploration difficult.
The mystery has drawn explorers like Josh Gates, who investigated the site in the Expedition Unknown episode on Africa’s Cursed Lake of Gold.
Military Artifacts Recovered
Divers have recovered a range of military artifacts from Lake Otjikoto. These include rifles, Mauser ammunition, artillery shells, and cannons used by German forces.
Some items are displayed in the Tsumeb Museum, offering visitors a glimpse into Namibia’s World War I history.
Recovered objects show that German troops used the lake to hide equipment. Visibility in the lake can be poor, and thick layers of sediment conceal many objects.
The artifacts serve as both historical evidence and a reminder of the events that unfolded in Namibia during the war.
Diving Expeditions in Otjikoto Lake
Otjikoto Lake in Namibia is a deep, water-filled sinkhole known for its role in World War I history. Divers explore it to document artifacts, map its underwater terrain, and recover items of historical value.

The lake’s depth reaches about 100–145 meters, making it unsuitable for casual diving. Only trained technical divers with experience in deep, cold, and low-light environments can safely explore it.
Visibility can change quickly due to silt stirred up from the lakebed. This can make navigation difficult and increase the risk of disorientation.
Diving is tightly regulated, as Otjikoto is a National Heritage Site. Expeditions often require permits and must follow strict conservation rules.
Equipment needs include specialized gas mixtures, redundant air supplies, and high-powered underwater lights. Safety teams often remain on standby at the surface to assist in emergencies.
Advanced Sonar Mapping
Expeditions such as those featured on Expedition Unknown have used advanced sonar to create detailed maps of the lake’s floor.
Sonar helps divers locate objects without disturbing the silt. It also allows teams to identify areas of interest before sending divers down.
Mapping equipment is often mounted on remotely operated vehicles (ROVs). These can reach depths and angles that are difficult or unsafe for divers.
Teams use data from these scans to create 3D models of the lake. This helps researchers plan safe dive routes and document the location of historical artifacts.
Notable Discoveries
During the retreat of German forces in 1915, they dumped large amounts of ammunition and supplies into Otjikoto Lake. Divers have recovered rifles, artillery shells, and other military equipment.
Some expeditions have located intact crates still resting on the lakebed. These finds offer insights into the logistics of the German colonial army during World War I.
In addition to weapons, divers have found personal items such as coins and tools. These smaller artifacts help historians understand the daily lives of soldiers stationed in Namibia at the time.
Many items remain in place for preservation, while others are displayed in museums in Tsumeb for public viewing.

Other Treasures and Shipwrecks in Namibia
Namibia’s coastline has revealed rare finds that connect to centuries of trade, exploration, and conflict. Some discoveries happened by chance during mining operations, while others resulted from targeted archaeological work.
The Bom Jesus Shipwreck
In 2008, diamond miners near Namibia’s Skeleton Coast found the remains of the Bom Jesus, a Portuguese vessel lost in 1533. Desert sands had buried it for nearly five centuries.
The ship carried gold coins, copper ingots, and elephant tusks. Archaeologists also found navigational instruments, weapons, and personal belongings of the crew.
Because the Bom Jesus was a state-owned vessel, it legally belonged to the King of Portugal. Portugal allowed Namibia to keep the treasure, which strengthened diplomatic ties. You can read more about the Bom Jesus discovery and its artifacts.
The Forbidden Zone
Namibia’s Sperrgebiet, or “Forbidden Zone,” is a restricted coastal area established by German colonial authorities in 1908 to protect diamond deposits. Access is still limited today, and permits are required.
This region stretches along the southern coast and includes part of the Skeleton Coast. The isolation has preserved many shipwrecks that might have been looted or damaged elsewhere.
Diamond mining companies, such as De Beers, have discovered several wrecks here during operations. Finds range from small trading vessels to larger ships like the Bom Jesus.
The Sperrgebiet’s restrictions help protect these underwater sites from human interference.
