Cyanobacteria in the Upper-Sûre Lake – Water sport activities prohibited

Due to a bloom of toxic blue algae (cyanobacteria) in the Upper-Sûre Lake, all water sport activities that implicate a direct contact with the water (swimming, diving, paddling, fishing …) are currently forbidden.
At this moment the solar boat tours, organized by the Upper-Sûre Nature Park, are not concerned by this prohibition.
