Key legal question
Whether the Gänseloch spring is a public source requiring a concession under cantonal water law.
Extracted holding
Yes. The spring is a large Bachquelle of public significance and therefore a public watercourse subject to concession.
Extracted reasoning
Its flow and steadiness place it within the category of Bachquellen, which are not covered by Art. 704 ZGB; cantonal law may classify such springs as public waters and subject their intensive, permanent use to concession.
