Štrbské pleso (csak tisztítóakción / clean-up event only)
Dived in practice only during the 'Čisté vody' (Clean Waters) eco-event: the most visited lake in the High Tatras, in the resort of Štrbské Pleso at about 1,347 m, 19.76 ha and 21 m deep with a very uneven bottom. The left side has deeper pits separated by a ridge at 5–6 m, one of them with the maximum depth and reportedly a 'hole' to 26 m. The bottom is several metres of very silty sediment over a thick layer of peat.
depth: 0–21 m
