The lake has an approximate length of 1.91 kilometers and an approximate width of 860 meters and an average depth of around five meters. It is divided into three basins, the north basin with a maximum depth of 12 meters with the island of Grabenwerder and the Liebesinsel, the city basin with a maximum depth of 9 meters and the small house lake with a maximum depth of 10 meters, which runs through the Amtswerder peninsula is separated from the city basin. Chalk was once mined on the islands in the north basin. The southernmost part of the Kleiner Haussee is known as the dairy bay because a dairy cooperative was founded in Feldberg in 1888.
The lake was heavily eutrophied by the discharge of urban sewage and especially by the sewage from the dairy . This condition did not change until 1980 by building a ring sewer, by the later connection to Feldberg to the sewage network and the biomanipulation (use of predators) between 1985 and 1999. The lake is on the widths Luzin drained after the water lilies channel for Narrow Luzin due the excessive eutrophication in 1969 was interrupted by a dam.
To the east of the Kleiner Haussee there are various private water plots, and at the dairy bay there is an allotment garden, the gardens of which do not extend to the water. On the southern third of the Amtswerder peninsula, there are also private water plots at the Kleiner Haussee and the city basin. On the other two thirds of the Amtswerders there is a floating stage at the Kleiner Haussee, which is mainly used for national and international water skiing events. There is a bathing area each on the north (north basin) and on the south-west bank (city basin) of the northern Amtswerder. There are also several sports facilities there.
The western part of the Amtswerder is joined by the center of Feldberg, which is located directly on the city basin. Here you will find again private water plots but also hotels directly on the lake and a public boat dock. The city park also follows to the northwest with a public boat dock. Followed by private properties, a specialist clinic and, in turn, private properties up to the youth hostel. To the north-east of the Liebesinsel is the Feldberger Hut and the seat of the Luzin Feldberg water ski club (WSC Luzin). Otherwise the lake is used for fishing.
Common fish species are: eel , pike , pikeperch , perch , roach , ruff , lead , tench and bleak , crucian carp , white bream , three-spined stickleback , carp , silver carp and catfish are rare . The American crayfish is native to the lake as a crustacean .
