This dive site, Kreidesee Hemmoor Einstieg 2, is part of a large chalk lake, an artificial creation resulting from opencast mining. It offers a distinctive freshwater diving experience with numerous abandoned mining gear and other items intentionally sunk for divers to explore, acting as an artificial reef. Navigation involves exploring these submerged structures and the unique topography of the former mine. The site's history as an industrial area provides a unique context to the underwater landscape.
The shallow and shore areas are rich with various underwater plants, providing shelter for a diverse array of fish species. Divers can expect to encounter char, trout, smelt, eel, perch, rudd, and tench. While not a coral reef, the aquatic flora contributes to a vibrant ecosystem within the lake.
The best time to visit Kreidesee Hemmoor for optimal visibility is during longer dry periods, where visibility can reach up to 25 meters. This site is suitable for divers of all experience levels, from beginners enjoying the shallow plant life and basic sunken items, to more experienced divers exploring deeper sections and more complex mining structures down to 25 meters. Freedivers will also find the excellent visibility and varied depths appealing.
