the Biggesee (also Biggetalsperre) is an artificial lake and lies in the southern part of the sour country, between Olpe and corroding thorn.

Table of contents


the lake serves for to the adjustment of Ruhr and Lenne and water supply for the Ruhr district and of the Bigge, a tributary of the Lenne, is fed.

Apart from the storage of drinking water for the Ruhr district the hydro-electric power plant produces approx. 24 millions a KW/H river in the year. The development achievement of the three large and small Francis water turbine amounts to 17.52 MW.

With the Listertalsperre in the area of the cities Meinerzhagen and Drolshagen the Biggestausee forms a large dam system. The formerly independent Listertalsperre attaches directly at the Biggestausee.

building of the Biggetalsperre

1956 passed the federal state parliament of North Rhine-Westphalia a law for the financing of the Biggetalsperre.

1. August 1956 came into force the Biggetalsperrengesetz; afterwards public utilities were obligated, of each water customer in the supply area 1,2Dpfg. to draw in ever cbm referred water as so-called “Biggepfennig” for the financing of the building of the Biggetalsperre.

The building of the Biggetalsperre began 1965 in the year 1956 and was terminated, planning hands back however in the year 1938 . From the year 1912 the coming Listertalsperre became tooa Vorbecken of the dam developed again. The overall system covers a pilot volume of 172 million m ³, of it is allotted 150 million to the Bigge and 22 million to the Listertalsperre. The catchment area of both dams covers an area of 289 km ². The seas have a water surface of8.76 km ² with a length of approx. 20 km. The largest depth of the Biggesees amounts to with the planned Stauhöhe approximately 52 M.

Approximately 2550 persons had to be resettled for the Biggetalsperre into the again built localities new Listernohl, separate Hanemicke and Eichhagen. 4.4 km federal highway became,14.8 km highway, 18.2 km circle and local roads as well as 31 km of edge ways, together 68.4 km roads and ways again built. For the new traffic routes the building of eight large valley bridges and 24 smaller bridges was necessary.

Also the Marien chapel forest castle had the building of the Biggetalsperresoft and again again one established on the bank of the Biggesees.

As check building a 52 meter high rock granular fill dam with an asphaltic concrete external sealing serves in the case of the Biggetalsperre. The Listertalsperre has against it a concrete dam.


in the course of the years have themselves the seas tooTourist magnets develops. Apart from the possibility for the water haven (sails, Surfen, paddles and fishing rods) on and in the Biggesee two person ships on the lake operate. There are also two official dipping places, the Weuste and the Kraghammer saddle. Besides numerous wheel and moving way lead approximately around the lake andinto the environment. Particularly to the summer time are used this active. Many the holiday-maker refer their accomodation in the camping sites around the lake.

About 100 hectars large island with the name, lying in the Biggesee, „Gilberg “is with the adjacent water surfaces as bird protected area classified andtherefore of the native simply bird island one calls.

As special exit goals in the proximity the cities corroding thorn and Olpe are to be called. They know comfortably with the help of the “Biggesee expresses”, a railway line along the Biggesees from Finnentrop to Olpe with some stops in the proximity of theLakeshore, to be reached.
