The Brunner Weiher is a still water in the area of ​​the Baden-Württemberg community Kißlegg in the district of Ravensburg in Germany .

location

The 6.4 hectare large Brunner pond , the village wells and five and a half kilometers northwest of the town center Kißlegg at an altitude of 699.3  meters above sea level. NHN , is privately owned and is used today for fishing.

Hydrology

The lake, first mentioned in 1735, was created in the late Middle Ages by overflowing a fen area and today has a catchment area of ​​around 69 hectares. The size of the water surface is 6.4 hectares, with an average depth of 1.7 meters and a maximum depth of 3.1 meters, the volume is around 109,000 cubic meters.

The main inflow of the lake is through several drainage ditches, the outflow via a Mönch to the Holzmühleweiher and from there via the Immenrieder Ach and the Obersee to the Wolfegger Ach and Schussen into Lake Constance and thus to the Rhine and ultimately into the North Sea .

ecology

Since 2000, Kißlegg and Bad Wurzach (catchment area only) have been involved with the Brunner Weiher in the action program for the rehabilitation of Upper Swabian lakes . An important goal of this program is to reduce nutrient inputs in streams, lakes and ponds and thereby improve and maintain the condition of the water bodies.

60 percent of the lake's catchment area is used for forest and 40 percent for agriculture - mainly grassland.
