Description
Morphology
Open conduit with a clearance that gives rise to a flooded meander through which it has been possible to descend about 4 metres in depth, until the narrowness makes passage unviable, although it continues descending.
Hydrology
It seems that this spring is the outlet of the waters, totally or partially, that run through the Sistema de la Bargadèra.
Progression
During the years 2005-2006 members of the GIEG and the EDES carried out clearance work and on 26 July 2008, members of the GIEG and of the Comissió Tècnica d'Espeleosub of the FCE made an attempt to get through. Josep Guarro entered the narrow flooded meander and managed to descend about 4 vertical metres until the fissure became too narrow, although it continued descending.
Other details
No survey is available.
