geography

General

The Ruschweiler See is one of three Ice Age lakes in the Illmensee municipality, separated by silting areas. Together with the Illmensee and the Volzer See , it forms a lake plateau. The actual water surface of the at an altitude of 691  m above sea level. Ruschweiler Lake located at NHN is 22,124 hectares, with a volume of 1,976,200 cubic meters and a maximum water depth of 17.3 meters. The mean depth is 8.9 meters. The catchment area covers 1057 hectares.

Emergence

The Ruschweiler See is a residual lake of a larger coherent Zungenbeckensee between the terminal moraines of the main and the first retreat stage of the last ice age, the so-called Würme Ice Age, around 18,000 years ago. The Andelsbach drains this basin. Since 1937 there has been a drop in the groundwater level of 1.3 meters.

Inlet and outlet

The inlet and outlet of the Ruschweiler See are via the Andelsbach, a tributary of the Ablach , which flows into the Danube . Coming from the Illmensee, the Andelsbach feeds the lake with an amount of 94 liters per second. There are also other small tributaries.

history

colonization

The Ruschweiler See is where Neolithic pile dwellings were found . In the course of a lowering of the lake level in 1937, the teacher J. Bohn and his students discovered remnants of a pile dwelling settlement on the east bank of the Ruschweiler See in an extensive reed area. The 4600 square meter area, which was heavily eroded by the impact of waves, was examined by the prehistorian Friedrich Garscha from the Badisches Landesmuseum in Karlsruhe. During an archaeological excavation in a single-phase pile field, parallel piles were found on a partial area . These reveal two-aisled post structures with a 3 × 4 meter area. In the 1950s, today's soil monument was often the target of private research and the targeted collection of prehistoric finds. In 1980, the Ruschweiler See was re-examined by the Baden-Württemberg State Monuments Office as part of the project to research wetland settlements on Lake Constance and in Upper Swabia. Further inspections followed in 1983. Investigations of the ceramics found allow an assignment to the Pfyn-Altheim group ( Neolithic : 4000 to 3500 BC). In Upper Swabia, this forms a spatial link in the transition from the Pfyner culture (Switzerland / Lake Constance) to the Altheimer group (Iller / southern Bavaria).

Todays use

It forms together with the Volzer Lake since 1987, the 70.6-hectare nature reserve " Rusch hamlet and Volzer Lake " and expanded to Illmensee the 263.1-hectare conservation area "Illmensee, Rusch hamlet lake and Volzer sea". The lake can be fished to a limited extent. The fishing season starts on May 1st and ends on December 31st. The owner is the Illmensee municipality. There are holiday homes on the north shore of the lake in the "Halde".

ecology

fauna

The Ruschweiler See is the territory of a beaver who has built a stately beaver castle here. In September 2014, a small, temporary wooden weir was built below the small stone bridge on the Andelsbach to prevent it from advancing further in the direction of “Gampenhof”. After a so-called “fish jam” formed in the spring of 2015, it was removed on April 27, 2015. The building was ordered by the regional council.
