Frequently asked questions

Which lakes in Czechia are best to swim in?

56 of 62 designated bathing waters in Czechia are rated Excellent for 2025 under the EU Bathing Water Directive. That class measures E. coli and intestinal enterococci only — it is not a safety clearance.

Is it safe to swim in Czechia lakes?

The official class is a bacteriological rating, not a safety clearance. It does not cover algal blooms, nutrients, water clarity, currents, or depth. Conditions change after heavy rain. Check local signage and the operator's current notices before entering the water.

Whose ratings do the Czechia lake pages show?

The publishing authority's own. Pages for lakes in Czechia show the values and classes that authority reports, with the season or year each was taken.
