Isbelle Karst Spring
Highlight • Natural Monument
When the stream "l'Isbelle" comes from an impenetrable layer of sandstone on the limestone ridge, downstream from
from the hamlet of Melines, she disappears. She's looking for her way further underground! This disappearance is caused by the presence of two small parallel fault lines, which are perpendicular to the direction of the valley of the Ourthe.
At low tide or under normal conditions, the Isbelle flow disappears at the first fault line for about 50m in a series of small and scattered sinkholes in the riverbed. This
are too small to be physically examined by humans. The water permanently feeds a “resurgence” or “karst spring” called “Fontaine de Thot”. In this place, just at the foot of the chalet of the “Spéléo Club de Belgique”, the water resurfaces before it flows into the Ourthe at the end of the Isbelle valley.
In a swollen river or after a thunderstorm, we can observe a saturation process and the water partly continues to the surface in the bed of the Isbelle, only then to submerge in the series of sinkholes of the second fault line. The water from these sinkholes feeds the second, but not permanent “karst source” of the Isbelle, about 100m from the bridge called “Pont des Gattes”.
