Dive Site Characteristics
Key Dive Site Facts
Dive Site Overview
Baumgärtli Immensee presents a distinct freshwater diving environment, characterized by an engaging underwater topography. Entry via stone steps leads divers to two main navigational paths.
To the left, a shallow plateau sits between 5 and 10 meters, rich with aquatic plants and often bustling with fish activity. Following the shoreline here eventually brings divers to jetty poles, signaling a turn-around point. The right side descends to approximately 16 meters, where a tree marks the foot of a significant wall.
This wall then slopes continuously to depths well beyond 40 m / 131 ft, featuring numerous cracks and holes that provide shelter for various fish. Along this deeper route, divers might encounter distinct artificial markers like a "DiveZone seasons greetings sign" or even a "decapitated flamingo." The site's versatility makes it suitable for extended bottom times at shallower depths or more technical deep dives, depending on the chosen path.
Best Time to Dive
Diving at Baumgärtli Immensee is favorable across many months, though conditions can vary. System data indicates excellent dive scores during cooler periods like January, February, March, September, October, and December, with good scores throughout the rest of the year. Air temperatures fluctuate significantly, from a chilly 1.8°C / 35°F in January to a warmer 20.7°C / 69°F in August. Rainfall remains relatively low year-round, typically averaging between 2.8 and 7.4 millimeters per month, minimizing its impact on dive conditions. While water temperatures aren't consistently reported, the generally cooler climate suggests suitable exposure protection is always advisable. Calm surface conditions are often ideal for exploring the deeper wall sections or the intricate shallow plateau near the shore.

Dive Experience & Conditions
The depth profile at Baumgärtli Immensee provides distinct paths for varying skill levels. Novice divers can explore the plateau at 5 to 10 meters, an area known for abundant fish life amongst the aquatic vegetation. More experienced divers venture right from the entry point to a wall that gradually descends past 40 meters. This deeper section tests buoyancy control as the wall slopes into the lake's depths. Visibility at the site can sometimes be reduced, particularly if suspended sediments are stirred. Water type is fresh. While the overall difficulty is rated easy to medium, navigating the deeper wall requires precise depth and gas management. Unique objects such as a fire extinguisher for a "3300th dive" and specific signs offer interesting navigational points.
Dive Difficulty & Safety Guidelines
Approaching Baumgärtli Immensee requires attention to skill level and environmental factors. Given its maximum depth, divers planning deeper excursions should possess Advanced Open Water Diver certification or higher, along with adequate gas planning. Monitoring depth and air supply is crucial, especially when following the deeply sloping wall, where uncontrolled descents could occur. The presence of large, submerged branches near the wall poses an entanglement risk, particularly under conditions of poor visibility. Divers should maintain good buoyancy control to avoid contact with the bottom and these potential hazards. Adhering to standard safe diving practices is essential, and consulting with local dive professionals familiar with current conditions is always recommended before any dive.

Marine Life at Baumgärtli Immensee
Upon entering Baumgärtli Immensee, divers will immediately notice the prevalence of freshwater fish inhabiting its varied underwater landscape. The shallow plateau, abundant with seaweed, serves as a thriving habitat where numerous fish congregate. Deeper along the sloping wall, burbots are known to seek refuge within the many natural cracks and holes in the rock face. While large pelagic species aren't a feature of this lake environment, the consistent presence of local fish life throughout the different depth zones makes for engaging observations. Exploring the crevices and plant-dense areas yields the most frequent encounters.
