The lake
Lake Mellensee
Lake Mellensee lies in the Töpchin valley, a meltwater channel from the last Ice Age. Its name probably comes from a Slavic word meaning shallows: much of the lake is shallow, and its deepest point is 9 m.
The River Notte flows in from the south and leaves the lake as the Notte Canal towards Königs Wusterhausen. The canal was built around 1600 to ship bricks and gypsum from the area to Berlin.
The guest house is in the centre of Saalow. The shore is about 2 km away, the beaches just under 4 km.
