2. About Source du Serre du Mazet

A Brief Description

• Type: Natural spring (mare)
• Location: Poulx, Languedoc‑Roussillon, France
• Coordinates: 43.880401 N, 4.408098 E
• Altitude: 130 m above sea level
• Geology: Upper Hauterivian (Cretaceous) limestone
• Hydrology: Restored by Lourde; outflow (exutoire) joins the Vistre river, capable of strong discharge during rain events

The spring was recently re‑engineered into a small mare (a shallow pond) to improve water retention and protect the surrounding habitat. The restoration work, carried out by the local water authority Lourde, aimed to preserve the spring’s natural character while ensuring that the Vistre—the downstream watercourse—receives a steady, clean flow.

Historical and Environmental Significance

Although there is no dedicated Wikipedia entry, the spring has long been part of the local landscape. Its Hauterivian limestone foundation dates back roughly 130 million years, offering a window into the region’s ancient marine environment. Over centuries, the spring’s reliable water source supported agriculture, livestock, and the daily life of Poulx’s inhabitants.

Today, the spring is valued for its ecological role: the pond provides a breeding ground for amphibians, a drinking spot for birds, and a micro‑habitat for aquatic insects. The occasional gros débit (high‑volume flow) after heavy rain showcases the spring’s dynamic nature, turning the calm pond into a lively cascade that feeds the Vistre and revitalizes downstream ecosystems.
