Understanding current dynamics is paramount for a safe and rewarding exploration of this distinct riverine world.
Best Time to Dive
Planning a dive at Tegna involves considering the distinct seasonal shifts, which influence conditions and overall experience. The cooler months, particularly January, February, November, and December, often present excellent dive scores. During these periods, average air temperatures range from 4.8-7.2°C (40.6-45°F), with minimal rainfall, typically between 1.59-3.74 mm. In contrast, the warmer months from March to October generally receive good dive scores, with average air temperatures climbing to 9.1-23.7°C (48.4-74.7°F). Rain levels are slightly higher then, averaging 5-8.51 mm. While colder air temperatures prevail during the 'excellent' months, the lower rainfall can contribute to more stable river conditions, making it worthwhile to brave the chill for potentially clearer dives, though water temperature data is not consistently reported.

Dive Experience & Conditions
The river's flow dictates much of the diving experience at Tegna, making current dynamics a primary consideration. Divers must account for the water level and quantity, which directly influence visibility and the strength of the current. Within the freshwater environment, visibility can vary based on recent rainfall and glacial melt. The dive itself is an exploration of submerged geological features, with light filtering through the deep green water to illuminate the smooth, sculpted rocks. Navigating swim-throughs and experiencing the unique sensation of diving beneath a waterfall requires careful buoyancy control and awareness of the surrounding riverbed. The maximum depth encountered is typically around 10 meters, making it suitable for divers with appropriate river diving experience.
Dive Difficulty & Safety Guidelines
Safety at this river dive site begins with mandatory protocols; divers must contact the local hydroelectric power plant via telephone both upon arrival and departure. This crucial step ensures awareness of potential changes in water levels or flow from upstream operations. Posted phone numbers are available at the entry beach and parking area. Additionally, divers are responsible for checking current water levels and flow rates prior to entering, as river conditions can fluctuate rapidly. Consulting with local dive shops or the SUSV (Swiss Underwater Sport Federation) is advisable for the most up-to-date site information and recommendations. Adherence to PADI Standard Safe Diving Practices is always paramount.
