Question juridique clé
Whether § 13 SchV is compatible with § 12 WRG and can restrict common use of public waters.
Solution extraite
The provision survives review under § 12 WRG because the government had broad delegated authority to regulate navigation, including limiting common use of public waters.
Motifs extraits
The delegation in § 33bis WRG was interpreted broadly, and the historical materials contemplated comprehensive regulation of navigation. Therefore the ordinance may validly constrain navigation on public waters.
