The source of the about 25 kilometres long Lison River, which is a tributary of the Loue River, is located (46°57'55.61"N 6° 0'42.99"E) in the commune Nans-sous-Sainte-Anne in the Département du Doubs. The source of the Lison River is a karst spring, the water flows from a giant cave portal below a cliff and then plunges down a waterfall.
The source is fed partly by the Ruisseau Château-Renaud, partly by the Lizon supérieur, both of which continues above and disappear in the catchment area of the surface and seep underground.
