etymology
The name of the upper course Kattenbach refers to the Kattnäse , a cliff protruding in the shimmering forest . Contrary to popular etymology, the basic word kat has nothing to do with cats, but refers to a lost adjective “small, low”.
The shamlah is mentioned in 1590 as shamlahe and at the end of the 15th century as shamlaw . It is possible that the root of shame "small" means certain, however, the meaning is not. The basic word -lah is related to English lake and German Lache and can also be found in Hurle . The optional ending -bach is explained by the loss of productivity of the original basic word -lah.
geography
course
The Kattenbach rises at an altitude of approx. 510 m above sea level. NHN at the Kattnäse in the Schimmerwald in the Harz National Park . In the valley between Kattnäse and Uhlenkopf, the Kattenbach has a steep gradient: in the first 650 meters after the source from approx. 510 m to 350 m above sea level. NHN , which corresponds to a gradient of around 24.6%. After about a kilometer, the Kattenbach touches the Ottenhai settlement , and at the same time a stream flows here on the left, which rises from the Eschborn . It passes under the state road L 501 (Ilsenburger Strasse) and flows through a campsite. It then flows through the Heinische Bruch , a piece of forest drained by drainage ditches. It leaves this 2.5 kilometers behind the source in order to flow into the agriculturally intensively used region of the Harz rim hollow. It flows like a trench east of Westerode .
After 5.1 kilometers, the Kattenbach united in Bettingerode with the mash Bach to Schamlahbach , 50 meters following the springing in Heini's break Lehmgrundsbach. After a further two kilometers, the Schamlahbach arrives at Lochtum and flows into the Ecker on the other side of federal highway 6 after a total of 9.5 kilometers .
Mapping and naming
The common naming of Kattenbach and Schamlah follows the statements in the official water quality report from 2002. In the area directory for the catchment area of the Weser and in the official map of the state of Lower Saxony, the name is above Westerode Kattenbach and in the further course Schamlahbach.
Structural quality
The stream drains an area north of Ottenhai that is used intensively for agriculture, but still maintains a certain closeness to nature thanks to its peripheral vegetation (older trees, bushes). The stream usually falls dry over long stretches in summer, which is given as the reason for a below-average biodiversity.
The brook is awarded the biological quality grade II up to Bettingerode , but from Lochtum onwards only with reservation due to a strong decrease in species and individual density. The fauna is dominated by river fleas, caddis and mayflies. The caddisfly species Tinodes pallidulus can be found on the Lower Saxony Red List .
Flood
In extreme floods, the shamlah in Lochtum can overflow its banks. The Lower Saxony State Forestry this developed the "Heini Bruch" which is aimed at restoration of the forest of the same name to the wetland project. This is intended to buffer the outflow peaks of the upper reaches and the clay base ditch.
