Is the water clean at Malafretaz - Plan D'Eau de la Base de Plein Air la Plaine Tonique?
Malafretaz - Plan D'Eau de la Base de Plein Air la Plaine Tonique is a lake bathing site with an official EU Bathing Water rating of Excellent for the 2025 season — the highest official classification under the EU bathing-water assessment. That annual classification comes from the EU Bathing Water Directive: national authorities test for two indicator bacteria, intestinal enterococci and E. coli, throughout the bathing season, then report the full-season results to the European Environment Agency (EEA) the following spring — the 2025 season's rating was published in spring 2026, and the 2026 season won't be rated until spring 2027. In addition to that yearly rating, some national authorities — for Croatia, the national environmental authority — publish individual water sample results during the season itself, ahead of the annual report. On site you'll find Sandy shore, Toilets, and Restaurant. There's parking about ~80 m from the beach.
That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. The most reliable swimming window here typically runs from July–September, with the sea usually at its warmest around August. Outside that window the water is cooler and often quieter. It's been a consistently reliable spot too — the rating has held at Excellent for 11 straight years. The nearest town, Montrevel-en-Bresse, is about ~800 m away.
That “Excellent” label comes from a full season of official water sampling, not a single test — it's one step on a four-point scale (Excellent, Good, Sufficient, Poor) reassessed once a year. Today's actual conditions can differ from the seasonal average, so for a live snapshot see the “Right now” and 7-day outlook panels above. There are 13 places to eat within a kilometre — Léa is the closest, about ~840 m away.
