Copacabana Kalsdorf
A roughly 6-hectare groundwater lake in Graz's southern recreation area, run as a training lake by the TSZ Copacabana dive centre. The south side has platforms at 2, 5, 7 and 10 m, navigation buoys and an underwater park with a Neptune statue, an artificial shark and a small plane. The main attraction is the M/S St. Wolfgang, an 18.6 m former Wolfgangsee excursion boat lying at about 10 m and prepared for wreck courses. Visibility is 2–10 m depending on the season; wels catfish, pike, zander and crayfish live in the thick weed beds.
depth: 0–12.5 m
