The question that lands on every Dolomites lake is always the same, and almost nobody answers it in a way you can check: can you swim here? The answer changes lake by lake, because each one falls under a different authority, and two lakes ten kilometres apart can have opposite rules.
Here the rule sits in the table next to the name, with the date we checked it and the source it came from. Where we have not checked yet we say so, instead of filling the box.
