Wasserlochklamm

The cave was dived in 2004 by the diving team of the Bat-Divers in 11 dives to its deepest point at 71 metres, completely surveyed and the 3 side passages navigated. The first, already discovered in 2003, rises vertically to 13 metres, becomes very muddy and smaller than 50 cm.The other two side passages turned out to be scales ending blindly: one at 28 metres horizontally (about 8 metres long), the other from 33 to 42 leads back to the main fissure. This scale is knife-thin at the edge and divides again in its course into several thin lamellae, which is why it was given the name 'air filter'.The main passage runs as a fissure gap with numerous scales and scourings in a length of 10-15 m and 1 - 4.5 m width in a south-north direction with a slight eastward deviation. It is inclined by 12 degrees to the eastand torqued vertically around itself up to 33 metres.It then runs at an angle of about 45 degrees to about minus 65 metres, and then runs straight out for 20 metres. Soil conditions: From 33 metres to 65 metres depth a scree of larger and smaller blocks of debris, from minus 65 metres to minus 71 metres first gravel, then sand. Then the siphon rises in a vertical, smooth-walled shaft, which was dived to 55 metres.Several small-volume but strong-current tributaries between 12 and 6 metres of water depth. Visibility varied between one and four metres, depending on the fill - most sediment is brought in by the tributaries between 12 and 6 metres water depth. The water level in the cave entrance fluctuated between 40 and 240 cm due to the weather, and the divers had to be "dragged" to the descent zone at times using hauling ropes and deflectors.
