			\|Project summary=In Wettingen there is a great example of a small nature-like bypass channel at the weir Wettingen on the Limmat downstream from Zurich which surmounts the very big height of 18.30 m. Nature-like bypass channels total length is 620 m, discharge 0.4 m³/s and additional attraction water is 0.6 m³/s. Total difference in water level is 18.30 m with high mean slope 3 %.The lower section consists of a technical fish.
			Whereas a near-nature water course was formed in the upper section, a rocky-cascade fishway with a height of 10 meters surmounts the biggest part of the altitude. Due to the limited space the
			lower section consists of a vertical-slot-pass which is converted into a collection-gallery at the power house.
			Leading back the water course to the power house is not possiblewhen it comes to bigger bypass channels.
			Splitting the water into two branches offers a good solution for this small channel. The main branch continues towards the tailwater as a near-nature water course and ends further downstream, where a connection to the natural river bed is possible. The smaller second branch diverts from the main branch towards the power house and is formed as a vertical slot-pass.

			The nature-like bypass channel has a trail on its side, so the residents can enjoy the lovely scenery and see some trouts when passing by.
