The dive
The Source du Cunhac is a sump entrance in the bed of the Lot at Saujac, opposite Cajarc, and not the Émergence du Ressel on the Célé, about 14 km away.
Profile and sections
The Source du Cunhac is a sump entrance in the bed of the Lot at Saujac, opposite Cajarc, and not the Émergence du Ressel on the Célé, about 14 km away. Divers call it Ressel II because its entrance looks like the Ressel's, but the likeness ends there. It lies just below the Saut de la Mounine, and the rock is dark, like in the Landenouse. A metal boat lies at 10 m. Then comes a round passage 5–6 m across at about -8 m, with current; the last section rises to -7 m, followed by a very turbid shaft and a boulder slope that closes down into tight side branches. One dive log from May 2023 gave 5 m visibility and 12 °C in the cave, and ~3 m visibility and 14 °C in the river.
The spring is named after Mr Cunhac, who showed it to Eric Lapouze-Troude in 1993. In April 1994 members of the B.R.E.N. explored the sump, first to 150 m and then to 240 m; that summer the team reached 360 m (end point at -41 m, deepest point -47 m). Dives in 2002 confirmed that the cave ends there.
Practical: there are no toilets and no compressor at the site.
- Depth and profile
- Deepest point -47 m, 360 m (1994); the 2016 survey gives 328 m and -45 m
- Configuration
- Backmount fine
- DPV: DPV possible (estimate)
- Large passages but short (360 m, -47 m); a scooter adds little
Who can dive where
- At least Full cave
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Goes down to 47 m (trimix or deco may be needed)
This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.
How to get there
Commune of Saujac (Aveyron), on the left bank of the Lot opposite Cajarc, just below the Saut de la Mounine. The entrance is in the riverbed at ~-11 m: you swim across the Lot, along a rope that runs from a tree to the cave entrance and spans about three quarters of the river. You park on the opposite (right) bank: through the village of Montbrun and along a field track that is passable without trouble, under the trees, with room for about 8 cars, within 100 m of the entrance.
