Before the dam was built, Mariental was flooded in 1923 and 1934. Floods after the commissioning of the dam occurred in 1972, 1974, 1976, 2000, and 2006. Since then, the dam's water level is kept at a maximum of 70% of its capacity to prevent both an overflow and an uncontrolled outflow through fully opened sluices.

Etymology
The name Hardap derives from the Nama word meaning "nipple" or "wart", which is how the surrounding area of low conical-shaped hills appeared to the early inhabitants. There are fishing spots at various points along the northern shore of the lake. Permits, and a map of permitted fishing areas, are available from the resort office, or from the magistrate's office in Mariental.
