Is the water clean at Plan D'Eau de L'Arche?
Plan D'Eau de L'Arche is a lake bathing site with an official EU Bathing Water rating of Poor for the 2025 season — below the EU standard; swimming may be discouraged or restricted by local authorities. 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 Sports facilities, Benches, and Trash bins. You can park about ~260 m away.
Over the 11 classified seasons on record, 10 have come back Excellent or Good — a track record worth checking each year rather than assuming. If you're timing a visit around water temperature rather than crowds, July–September is the safest bet, with August typically the peak — expect a cooler, calmer sea either side of that stretch. Monnaie — the closest town — sits about ~700 m from here.
That “Poor” 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. Worth noting: the rating slipped from Good to Poor in 2025, so it's especially worth checking the latest local advisories. There are 4 places to eat within a kilometre — Le Coq Hardi is the closest, about ~280 m away.

How is the water quality rating measured?
National authorities sample the water for intestinal enterococci and E. coli bacteria through the bathing season and report the full-season results to the European Environment Agency each spring for the season just finished, which assigns one of four annual classifications — Excellent, Good, Sufficient or Poor — under the EU Bathing Water Directive. Some national authorities, including Croatia's IZOR, also publish individual in-season sample results ahead of that annual report.
