ハウゼン・イム・ヴィーゼンタルの湖・トップ18

The Hornberg Basin near Herrischried is Germany's highest reservoir and part of the Wehr pumped-storage power plant. A variety of trails lead around the basin through the extensively planted landscape, which, upon completion, was designed with around 40,000 trees and shrubs. There are also numerous other hiking options and refreshment stops nearby.

The Eichener See (popularly known as Eiemer See in Alemannic) lies above the Schopfheim district of Eichen in the Lörrach district and is a karst lake that only appears intermittently. The lake only has water when the groundwater level is high and lies in a hollow (shell limestone karst basin). It has no surface inflow, the outflow occurs partly underground and partly through evaporation. Geologically, it is a sinkhole that is temporarily filled with water, in which groundwater comes to light, especially after the snow melts or after long periods of rain. In dry phases, the ground distance (difference in height between the groundwater table and the earth's surface) can be up to 40 m; The deepest point of the trough that stores the groundwater is around 48 m below the earth's surface. The background to the strong fluctuations is the cavities in the Dinkelberg, which is mainly made of shell limestone, which can fill with water very quickly due to a groundwater backup, but only empty again slowly. The lake was first mentioned in a document in 1771, when five people drowned in it from a capsized boat. People also died in the lake in 1876 and 1910. Source: Wikipedia

Nice view and a huge storage

Wonderful to reach by gravel or road bike

The lake is always worth a trip

Cool natural spectacle above oaks. The lake only appears when the groundwater level is high, and there are rare primeval crabs in the lake

A lot of people go for a leisurely run or bike here and enjoy the wonderful nature around the Eichener See - it's great here!

A dolienensee that only appears when the groundwater level is high and then disappears again. There are rare crabs.
