Course of the river 
The Waag rises in the mountains of Gross Stärnen and Chli Stärnen at the Schwyz Alps, in the municipality of Oberiberg, and flows north-northeast into the village of Unteriberg.

At Laueli, the Waag reaches the valley floor, where the artificial Sihlsee reservoir flows into it. It initially crosses the valley in a north-easterly direction, before it takes the Weglosenbach at the Weglosen valley station and turns north. Immediately afterwards, the Gänigenbach flows into it from the east in Fuchsenweid, than proceeds to flow alongside the H386 road.

The Waag passes Lehweid, Hintertwingi, Twingi and Vordertwingi, where the Sitibach flows towards it from the east, before it resumes its northeasterly course. It then passes the villages of Waag and Herti, before finally flowing into the Minster river.
