The Lassnitz is a tributary of the Kainach in western Styria .
geography
The Lassnitz is a small torrent . It rises in the Kohlgruben on the northern slope of the Steinberg in the municipality of Ligist .
The Lassnitz flows between the settlement areas
- Laßnitz (written with ß according to the official map), Grabenwarth and Holzberg in the north as well
- Rauchegg, Rubmannsberg and Bubendorf in the south.
The stream flows into the Kainach north of Bubendorf.
In the middle reaches the Lassnitz forms the border between the communities Mooskirchen and Ligist , cadastral communities Steinberg and Grabenwarth. The lower reaches (from the Holzberg settlement) is the border between the communities of St. Johann-Köppling and Mooskirchen.
In the northwest of the upper reaches of the Lassnitz, in the cadastral municipality of Steinberg, there is a settlement area that bears the name "Laßnitz". Because of its local proximity to Grabenwarth, this settlement is often counted as part of Grabenwarth in everyday life.
About 1 km south of their sources is the Steinberg motorway junction of the A 2 south motorway .
Navigation systems can confuse the water with two other rivers:
- the 18 km in a straight line south lies also in Western Styria river Laßnitz in Germany Berg and Frauental an der Lassnitz or
- the river Laßnitz near Gleisdorf , located approx. 32 km eastward in Eastern Styria .
Names
The water has been given different names.
In the 18th century the brook is called "Lahensbach", in the 19th century it was called "Lachnitz".
In the maps based on the re-registration in the middle of the 20th century, the water was referred to as the "Rumerberg Bach". It can not be verified whether this naming was an attempt to use the name of the neighboring Rubmannsberg settlement as the basis for the name of the water in order to avoid confusion with the Lassnitz near Deutschlandsberg . The settlement of the same name today on the north bank of the Laßnitz was shown in this map generation as "Laßwitz".
From 1983 the brook is called "Laßnitz" in the maps of the official regional survey. The new edition of the official maps in 2009 uses the spelling "Lassnitz".
Information that calls West Styria a river Laßnitz can refer to the small brook near Ligist or three rivers in the Deutschlandsberg area: the upper reaches of the Lassnitz (Niedere Laßnitz), the wild brook (Hohe Laßnitz) or the Rettenbach (also Niedere Laßnitz called).
Another river in Styria called Laßnitz is located in East Styria east of Graz, mainly in the municipalities of Laßnitzthal and Gleisdorf . This Laßnitz belongs to the river system of the Raab (river) .
The name "Lassnitz" and its spelling variants such as "Laßnitz" is derived from the Slavic "Lieznica" and translated as "Waldbach". In linguistics, * loNč'nica "Wiesenbach" is also discussed for Laßnitz (890 Luonzniza) , as a further possibility (1345 Lesniz, Laßnitz near Murau or 1080 in Paltental Laznich) * laz'nica "Gereutbach".
history
The name of the Lassnitz is evidence of an old Slavic population. The settlements in the vicinity of the brook have Slavic and German names, although Celtic roots of names from the previous settlement period can still be proven.
The German roots can be traced back to the settlement from German-speaking areas from the 8th century onwards as part of the development of the Karantanische Mark on the Sulm and Lassnitz rivers .
The water is located in the area that was administered in the Middle Ages around Söding by the Cistercian Rein monastery north of Graz . Information about a body of water near Söding called "Lachitz", "Laßnitz" or similar refers to the stream described here, not to the Lassnitz river near Deutschlandsberg. The Rein near Graz was instrumental in the settlement of the Kainachtals and the Central Styria south of Gleinalm involved.
The name Kohlgruben for the area in which the Lassnitz rises is not a reference to coal mining (there are no coal seams in the block gravel or mica slate of the area), but to the activity of charcoalers in the production of charcoal .
The Lassnitz only flows permanently into the Kainach since the large-scale Kainach regulation in the 20th century.
Before that, the mouth of the Lassnitz was dependent on the course of the Kainach. This course could change significantly after floods. In this way, the Lassnitz partly flowed directly into the Kainach, sometimes it flowed into a mill stream of the nearby Grössl mill or into the Lahnbach, which ran parallel to the Kainach or even formed its upper course. The name “Lahnbach” is not derived from the old German word for avalanche, not even from Lehne (there are no steep or long slopes in the area where avalanches usually occur), but from the Celtic “Lahn (e)” - sluggish water .
environment
The Lassnitz flows through forests and agricultural areas. The settlements in their catchment area are not located directly on the water, but on the slopes around them.
fauna
Dragonflies and caddis flies live near the water. Their larvae are a reliable indicator of water quality; they only occur in bodies of water with good to very good water quality.
After heavy rainfall in thunderstorms, etc., the stream can emerge from the banks. The resulting small pools of water and the courses of small channels from the catchment area of the stream form the basis of life for swarms of gels.
The only hunted game in the area is mainly hares and deer or foxes.
Water quality
The water quality is quality class I-II (almost unpolluted, in practice almost drinking water quality). The adjacent pastures can cause less pollution.
The water hardness is low (range 1–2 - soft water).
Floors
The agriculturally usable (or previously used as such) soils on the Laßnitz are lime-free brown soils from crystalline slate in the upper reaches (rock brown soils ), in the middle reaches on the slopes partly sedimentary brown soils as medium-quality arable and grassland with a good water supply. The base material of the soils are metamorphic rocks ( crystalline of the Koralm ). The valley of the brook is gullied .
On the road between Laßnitz and Rauchegg south of the Krakl property there is a soil protection point (VOX 4) according to the Styrian Agricultural Soil Protection Act. In Styria, the Soil and Plant Analysis Department of the Agricultural Experimental Center created a network of over 1000 examination sites in 1986-2006 to assess the degree of pollution of agricultural soils due to pollution, erosion and compaction Numerous parameters (general soil parameters, nutrients and pollutants) are continuously examined.
Agriculture and Forestry
Agriculturally used areas are used as fields and pastures. A widespread breed of cattle is the Fleckvieh (so-called "check (s)").
The small forest area is used by the landowners as required; it is too small for independent, large-scale forestry.
geology
The source area of the Lassnitz in the Kohlgruben area lies in the crystalline rock ( gneiss and garnet mica schist ) that make up the Steinberg area.
The course of the stream then touches a narrow zone of gravel (Schwanberger block gravel ) and block rubble from the older Baden (lower bathing area ). The rock blocks in it can be over a cubic meter: This zone is a shoreline of the former sea in the Graz Basin. It is associated with a phase in which the Styrian foothills were raised. The level of the Graz Basin began to emerge around 23 million years ago. The basin itself is formed by rocks and deposits of a former sea from the Neogene (formerly Young Tertiary), at its edge - as here in the Laßnitztal - younger deposits lie.
The Lassnitz then flows between hills made of gravel-bearing sand or clay, which was created by deposits of old rivers in today's Kainachtal. This subsoil belongs to the so-called Stallhofer layers from the Lower Baden, up to approx. 16 million years old, which was last formed into today's landscape in the Ice Age (approx. 1.8 million years and younger). The gravel layers are also called "Eckwirt gravel, layers of pure". The Eckwirt gravel is mostly heavily weathered crystalline and quartz gravel with layers of sand in between. The layers of Rein contain freshwater marl and limestone , clays , sands , etc. Where the Lassnitz flows from the hill country into the Kainach valley, there are gravel terraces from the Ice Age . The Holzberg and Bubendorf settlements are located on such terraces.
The Kainachtal at the mouth of the Lassnitz consists of deposits, the max. 12,000 years old ( Holocene , "post-ice age").
There are two drilling points on the middle course of the Lassnitz, a third drilling point is in the headwaters in the Kohlgruben area. What was searched for in each case (groundwater, coal, oil, geological foundations) and the results of these boreholes can be found in the records of the Federal Geological Institute .
The rock in whose area the Lassnitz rises (Koralmcrystalline) sinks rapidly to the east and is covered by deposits (gravel, etc.). These deposits are around 100–150 m thick at the confluence of the Lassnitz and Kainach. As a result, the rock near Söding is already approx. 379 below sea level, thus under a more than 700 m thick layer of deposits.
The geological subsoil belongs to the Lieboch sub-basin of the West Styrian Basin, which is part of the Styrian Basin.

The small tributaries in the Kainachtal confirm this interpretation: they are “flat and full” (with water that cannot drain quickly due to the lack of a gradient and promotes swamping).
