Best for beginner divers, 20-40m, shore entry.
Gaswerk is a freshwater shore dive located in the Zürichsee. The site features a steep drop-off, with depths ranging from 20 to 40 metres. Divers should expect visibility between 5 and 10 metres, which can fluctuate due to thermoclines encountered during descent. The site has no current, allowing for focus on buoyancy and depth management. Given the depth, nitrogen narcosis is a risk, and divers must monitor their limits closely. Cold water temperatures are typical, making a drysuit or thick wetsuit advisable. Surface boat traffic is an active hazard, requiring caution during entry and exit.
