Kreidesee Hemmoor is a freshwater lake featuring steep walls, drop-offs, and artificial structures including a former fish farm. The topography includes a wall descending to 55 metres and a submerged forest area known as the male forest starting at 35 metres. Divers can expect depths between 10 and 45 metres with visibility ranging from 10 to 30 metres. Due to water temperatures hovering around 14°C and dropping to 5°C at depth, drysuits are highly recommended. Shore entry is available, and the site offers comprehensive facilities including air fills, showers, and a dive shop. Hazards include cold water, significant depth, potential entanglement, and variable visibility.

Ultraleichtflieger is an artificial reef site located within Kreidesee Hemmoor. This shore-entry dive is suitable for beginners and offers a calm, shallow environment for exploration.
