This dive site, Hohendeicher See, is notable as Hamburg's sole dedicated diving location, offering a unique freshwater experience. Divers can explore an underwater parkour, primarily found at depths between 5 and 9 meters (aligning with the site's stated maximum depth). The lake is easily accessible from multiple shore entry points, with the DUC entrance (Warwischer Hinterdeich 55) serving as a popular starting point. While there isn't extensive historical information provided, its significance as the region's only dive spot makes it a local recreational hub.
The Hohendeicher See supports a variety of aquatic life typical for a temperate freshwater lake. Divers can expect to encounter pike and eel, which are specifically mentioned as being present. Beyond these larger inhabitants, the site is home to various species of small fish, contributing to the appeal for underwater photographers interested in macro subjects.
The site is particularly well-suited for photographers due to the interesting underwater parkour and the diverse small aquatic life. Given its shallow average depth of 4 meters and maximum depth of 9 meters, it is an excellent location for both snorkeling and freediving. Visitors should ensure they park responsibly, avoiding private property. The best time to visit for diving is generally during the warmer months, although dedicated dry suit divers can explore year-round.
