The dive

In August 1984 the sump was extended by 470 m, to 700 m from the entrance. There are no recent reports and no data on visibility, temperature or flow.

Profile and sections

In August 1984 the sump was extended by 470 m, to 700 m from the entrance. There are no recent reports and no data on visibility, temperature or flow.

Depth and profile
Sump of ~700 m, 2–3 m wide and ~2 m high, -6 to -8 m. At 320 m a low section of ~15 m (1 m high). At 690 m the passage splits: bearing 20° a sediment-filled gallery (50–70 cm high, not explored), bearing 310° a narrow passage with a boulder choke, followed ~10 m to a squeeze.
Configuration
Roomy, shallow sump: every configuration seems to fit up to and through the low section at 320 m (1 m high); the side branches after 690 m are narrow (estimate).
DPV: DPV possible (estimate)
700 m shallow sump, 2–3 m wide: a small scooter can help, with the low section at 320 m as the bottleneck (estimate).

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from public sources: plongeesout (FFS), Wikipedia, the FFS congress page on the Touvre (2009), FFESSM Subaqua (2018), the Spit Club Saint-Maixentais, CDS 79, BRGM (1974), the communes of Touvre and Magnac-sur-Touvre, Rivières de l'Angoumois, ABIMES, GESMA, the La Rochefoucauld caving club (ARSR), the FFESSM Nouvelle-Aquitaine club directory and MedSubHyp (September 2026), and for Le Paradis Blanc Divernet (2016), Aquatek and the Charente prefecture (Oct 2026). Much of the dive data is old (1951–2019) or comes from a single club report. Pins only from published coordinates (Gros Roc); the Touvre springs and the Sources du Cros from OpenStreetMap; the three Deux-Sèvres sites approximately at the centre of their commune (CDS 79, message, Oct 2026); the Glane from Grottocenter; one spring and Le Paradis Blanc have no pin yet. ~ = estimate.
