Lake Otjikoto
Type III: CMAS sinkhole type (as reported in 2009) [1] (Classification reported in a 2009 newspaper article; no current CMAS document was found to confirm it.). Ces catégories sont propres au système de certification mentionné ; elles décrivent la formation requise pour le site.
A heritage sinkhole lake near Tsumeb whose 'underwater museum' of 1915 weapons lies at about 41-55 m. Diving has been limited to organised and authorised groups.
Divers enter Lake Otjikoto from its shore; in 2009 an entry ladder reached down to 6 m. Below, named features step down the wall from about 28 m, and the dumped weapons lie at roughly 45-55 m. One 2025 report says divers need to be qualified to at least 50 m to explore them.
The lake is a public heritage site where visitors pay to view it from the rim, but diving is not open to casual visitors. Earlier reports describe dives run through the Namibian Underwater Federation and authorised operators, and training use by police divers. Current diving arrangements should be confirmed with the National Heritage Council of Namibia.
L'environnement
Still, fresh water in a steep-sided sinkhole, about 22 C near the surface and 18 C lower down in 2009, with visibility up to about 15 m. Narrow caves lead off at depth.
Conditions
Temperature and visibility from 2009; the water level rose sharply after the 2025 rains.
