About "Haus am See”

The "Haus am See” as a centre of education and information was built at the north bank of the lake Muldestausee in the years 1993-1994  as an institution of the Anhalt-Bitterfeld district’s office for nature protection, forests and waste management.

Frau Grießbach und Frau Kunze 2010

Manager of the center: Susanne Grießbach and Sabine Kunze.






The institution aroused by reason of promotion of professor Klaus Töpfer and the Deutsche Bundesstiftung Umwelt DBU Osnabrück.

 In the centre there is a large permanent exhibition showing more than 80 preparations of indigenous animals and giving information about the Mulde Reservoir´s history as a former opencast mine.

In addition there are special events such as creative workshops and lectures on interesting topics as well as holiday programmes for families several times a year.

Directly beside the "Haus am See" there is a didactic garden with a heath, herbal, rock and peasant garden.










A 16 km long nature trail runs closely past the house alongside the Mulde reservoir.











 Numerous educational offers are submitted by the "Haus am See". For example, there are guided tours to the exhibitions, lectures about the opencast mines Muldenstein and Goitzsche and about the history of the Mulde reservoir as well as excursions into the surrounding nature and to the witnesses of lignite mining.

The educational and leisure time offers of the "Haus am See" are used by about 7.000 visitors a year.
Hides for stroking of the Elbe-beaver, the fox and the wild-boar belong to the exhibition as well as numerous nests of birds, hornets and wasps. There is nothing as attractive as living animals. In the lecture room, there is a beehive for display, which usually attracts crowds of visitors. The changes of landscapes as a consequence of lignite mining are shown on large display boards in the convention room.

A replication of an oligotrophic grassland community is typical for the surrounding former mining areas
A shallow artificial pond invites visitors to identify plants in silting areas and to observe animals near the water.
The16 km long nature trail "Former mining region Muldestausee" offers environmental education with different areas of experience.

Osprey LiveCam

Logo Fischadler



The osprey live cam is sponsored by the EU Community Initiative LEADER+.
You can watch the osprey in the area around the Mulde reservoir, which is embedded in the Dübener Heide Nature Park.
It lives mainly on fish and prefers open and pure water bodies as a hunting ground, that are abundant with fish.

Lebensraum Mulde 








 The Mulde reservoir with about 24 different species of fish and its neighbouring exhausted opencast pits and the Mulde River form an ideal habitat for osprey. 
In 1995, a couple of ospreys settled  in a man-made eyrie on a former pylon in the nature reserve "Tiefkippe Schlaitz" for the first time. 
By 2011, 29 young ones have been brought up.
In a nationwide ringing programme, 29 of them have been tagged with a ring indicating the ornithological station.

A male osprey, that had hatched out in 1999, settled in 2002 in the Misery Wet Lands, which are situated 30 km south of Paris and 802 km southwest of the ringing station. In 2009, 5 couples of the fascinating ospreys were hatching in the Bitterfeld region.
Visit the Dübener Heide Nature Park!

Plenty of information about that rare breeding bird can be found in the information centre "Haus am See" in Schlaitz.

Kamera Fischadlermast

Since 5 April 2006, a camera has been transmiing pictures from what’s happening in the eyrie directly onto a large-format screen in the information centre
"Haus am See"

You can experience excursions to the breeding ground of the osprey couple and watch the birds fishing and staying in the eyrie.
A nature trail leads from the information centre to an observation point, which lies within the visibility range of the eyrie. From that point, you can watch the birds with field glasses.

In the information centre, you can watch a live transmission from the eyrie.
We could identify 30 tagged ospreys because of our intensive observation in the years 2006 to 2011. In Germany ospreys were tagged with colored rings since 1995. Since the year 2000 they only use black rings.

Ringnummern der FA 2010






You get information about the birds’ biology, their migration routes, the upbringing of their young and, naturally, everything important about "our" couple of ospreys and its descendants. 
Members of our staff report in entertaining public lectures about their observations.

Many tourists and nature lovers won’t miss this: live watching the ospreys build their eyries, lay their eggs and care for their young.

On December 17th 2007, the project was awarded a commemorative medal for the exemplary implementation of the LEADER+-Idea by the minister for agriculture and the environment of the state of Saxony-Anhalt, Mrs. Petra Wernicke.
