Dive Site Overview

Once a working lignite mine, Singliser See has transformed into a popular recreational area, now equipped for diving instruction and exploration. Lake's unique character stems from its geogenic acidity, with a pH typically ranging from 3.8 to 4.9, influenced by sulfur-containing minerals.

Despite this, water clarity is often exceptional, averaging about 8 meters Secchi depth, though actual dive visibility generally falls between 2 and 8 meters, with a reported average of 4 meters. Divers can navigate a dedicated underwater course and explore three diving platforms; two are placed at 5 meters and 8 meters, suitable for training and skill refinement. Recreational diving depths extend to 25 m (82 ft), allowing for exploration of deeper sections where thermal stratification is present.

Entry is convenient via a jetty with stairs, leading directly into this freshwater site, which features a predominantly sandy bottom.

Dive Experience & Conditions

Descending into Singliser See, divers generally encounter clear water, averaging 4 meters of visibility, though it varies from 2 to 8 meters. Diving occurs as a shore entry, typically via a jetty with stairs, simplifying access. Maximum depth of this lake is 25 meters; recreational diving often occurs in shallower sections, where the impact of the lake's unique chemistry is less pronounced. Two dedicated training platforms are situated at 5 meters and 8 meters, offering stable structures for skill development. Below 20 meters, divers might notice low oxygen levels and significant thermal stratification, characteristic of similar lake environments. No consistent current exists; navigation across the predominantly sandy bottom remains straightforward.

Dive Difficulty & Safety Guidelines

An important tip for divers at Singliser See is to remain vigilant about surface activities; significant surfing can occur, particularly during warmer months. The water's acidic nature, with a pH between 3.8 and 4.9, means divers should ensure their equipment is suitable for freshwater exposure and consider appropriate exposure protection to maintain comfort. While there is no reported current, divers should still be mindful of thermal stratification, especially when exploring deeper sections below 20 meters where oxygen levels decrease. Emergency services can be reached by dialing 112. The site operates with free access, but sufficient paid parking is available, and facilities such as hospitality services are typically present.
