Fig. 10: The intake pipe from the pumping station in Rüschlikon on Lake Zurich. Here, drinking water is drawn in from a depth of 40 metres. First photo after ten years in Lake Zurich. The lake was exceptionally clear, especially since I was all alone at the dive site that Friday. Two Sea&Sea YS-110 strobes with Glowdive diffuser domes.
