Scope of work

Die Aufwertung der Mittleren Bucht stellt die zweite Etappe des Gesamtkonzeptes der Aufwertung des Südufers des Alpnachersees dar. Das Teilprojekt umfasst die Schüttungsmassnahmen für die naturnahe Gestaltung des Uferbereichs. Primär wird der Seegrund mittels Schüttung angehoben, um Flachwasserzonen schaffen zu können. Dazu können Aushubmaterial der Projekte HWS Sarneraa, WBP I Sarneraa-Alpnach sowie aus den Steinbrüchen Guber und Rischi genutzt werden. Insgesamt werden 110'000-140'000 m3 (lose) Aushubmaterial angeliefert. Damit können rund 3 ha Flachwasserzonen geschaffen werden.
