2026 in-season sample timeline
No individual in-season sample feed has been published for Moncontour - Plan D'Eau Du Grand Magne (La Dive) yet. The official 2025 classification above, from the annual EU Bathing Water report, is the most current rating available for this beach.
How measurement works
Under the EU Bathing Water Directive, national authorities take water samples through the bathing season and test them for two indicator bacteria: intestinal enterococci and E. coli. Higher counts of either indicate a greater risk of contamination from sewage or agricultural runoff.
At the end of each season, the full set of results is reported to the European Environment Agency, which assigns one of four classifications — Excellent, Good, Sufficient or Poor — based on the statistical spread of the last four seasons' samples, not a single reading. That's why the rating published in spring 2026 covers the 2025 season, and why one bad sample doesn't necessarily change the rating on its own.

Frequently asked questions
Is it safe to go in the water at Moncontour - Plan D'Eau Du Grand Magne (La Dive)?
It passes, but only just: the 2025 classification is Sufficient, the minimum passing grade, so a quick check of local advisories is worthwhile first. That applies to the water around Deux-Sèvres.
How is bathing water quality measured?
Water samples taken through the bathing season are tested for two indicator bacteria — intestinal enterococci and E. coli — with the full season's results reported to the European Environment Agency the following spring, which grades the season Excellent, Good, Sufficient or Poor under the EU Bathing Water Directive. Some national authorities, including Croatia's IZOR, also publish individual in-season samples ahead of that annual report; that isn't yet available for Moncontour - Plan D'Eau Du Grand Magne (La Dive).
How often is the water tested?
Testing happens throughout the season (typically 4+ samples, May–September), but the resulting classification is only published once, the following spring. Moncontour - Plan D'Eau Du Grand Magne (La Dive) doesn't yet have a published in-season feed, so the annual rating above is the most current figure on hand.
