The Minster is a river in the Swiss canton of Schwyz and a tributary of the Sihl river. It has a length of 13.1km (08.1miles). Since the creation of the artificial Sihlsee reservoir by impounding the Sihl, the Minster now flows into the reservoir rather than directly into the river.[1]
The river's headwaters lie near the Ibergeregg pass, on the slopes of the Furggelenstock and Firstspitz mountains. From there it flows in a north-western direction to the villages of Oberiberg and Unteriberg. Between the two villages, the river flows under the Jessenenbruecke bridge. Some 1km (01miles) below this bridge, the Minster receives the waters of the Waag river, whilst a further 1km (01miles) on, it flows into the southern end of the Sihlsee.[1]
