Other people's footage, not advice: how someone else dives here says nothing about what suits your team. Dive within your training.

The dive

In the blue season the water is ~24 °C and visibility ~40 m. After closing in 2005, the lake has been open again with an environmental licence since 2011.

From about October to April algae can cloud the water; shallow activities are then sometimes suspended.
