Federal Act
on the Protection of Waters
(Waters Protection Act, WPA)

¹The in­tro­duc­tion of sol­id sub­stances in­to lakes is pro­hib­ited even in cases where these sub­stances would not lead to pol­lu­tion.

²The can­ton­al au­thor­it­ies may per­mit the cre­ation of em­bank­ments:

a.

for the con­struc­tion of build­ings in built-up areas which can­not be loc­ated else­where if an over­rid­ing pub­lic in­terest re­quires such an em­bank­ment and the pur­pose in view can­not be at­tained in any oth­er way;

b.

if a shal­low wa­ter zone may be thereby im­proved.

³The em­bank­ments cre­ated shall be as nat­ur­al as pos­sible, and all bank flora des­troyed shall be re­placed.
