Staffelsee
The Staffelsee is a lake in the Garmisch-Partenkirchen district of Bavaria, Germany. The settlements of Murnau, Seehausen and Uffing lie on its shores. Within its area lie seven major islands, the largest of which is Wörth. Boat trips aboard the MS Seehausen (built 2009) connect the landing stages of Seehausen, Uffing and Achele (Murnau) between April and October. The surface of the lake is, on average, above sea level, and at its deepest it is around deep.
The main inflow and outflow of the lake is the River Ach, which enters from the west and departs to the north.
