The Lutter is a brook that rises on the edge of the Elm near Königslutter and flows into the Schunter after 7.5 km from the left . The hard , strong calcium - and bicarbonate -containing spring water originates from a Karst source , with an average bulk (20,000 m³ per day) of 230 l in the second one of the strongest sources in Northern Germany. The Lutter gave the place Königslutter its name.
Surname
The term Lutter is down German and related to " Loud ", which in the Middle High German for loud, bright, clean, clean is. That should have played a role here when naming the water because of its pure spring water. Lutter is a common river or stream name, but also occurs in place names, such as Lutterbeck, Lutter am Barenberge . The synonymous "louder" is still used today as an expression, e.g. B. a "pure character". Today's Königslutter was first mentioned in 1135 as Lûtere . The naming as Lutter was based on the stream flowing through it. At the end of the 14th century, it was given the addition "Königs-" because of the king and later Emperor Lothar von Süpplingenburg, who was buried in the Kaiserdom Königslutter .
geography
Lutterspring
The Lutter spring is one of the strongest springs in northern Germany with an average discharge of 800 m³ per hour. This is due to the fact that it is a karst spring .
The source is located south of Königslutter on the Elm road upwards. Below the spring, the water gushes out of six further spring pots in a flat area and forms smaller ponds. The source was named as Abbot Fabricius source , but is better known as Lutterspring , after which the forest restaurant above the source was named. Lutterspring with the Quellenhaus and the temporarily operated restaurant has been a tourist destination since the beginning of the 20th century.
course
The spring area with the spring pots is a park-like area. From here the Lutter runs in two branches of the stream in a north-easterly direction to Königslutter, about 1 km away. A hiking trail runs parallel (Unter den Eichen) . The stream flows through the village - also through the grounds of the AWO Psychiatry Center - and is partially built over there. He crosses Mühlenstrasse and comes to the surface at the Zur Herrenmühle inn . To the east of the city wall by the moated castle, the bank of the Lutter is overgrown in sections. It also flows through the former sugar factory site and what is now the Centro Kö . Below the village it runs a few kilometers to the northeast and north and flows into the Schunter after about 8 km between Beienrode and Groß Steinum .
The hard, mineral-rich water of the Lutter was used in previous centuries by 73 breweries in Königslutter to brew the top-fermented Duckstein beer . The Lutter's water power was used by up to ten water mills , of which there were seven in Königslutter in 1403 alone. They served as grain , oil , fulling , paper and powder mills .
Water quality
The upper reaches of the Lutter above Königslutter shows hardly any pollution and in 2002 was assigned quality class I-II, although only three species of mayfly larvae ( Baetis rhodani , Baetis vernus and Cloeon dipterum ) and one genus stone flies ( Nemoura ) are represented in the entire water . However, 63% of the species native to the Lutter are typical of rivers. In the further course of the water the pollution increases, so that the rest of the run was classified in quality class II.
In order to implement the EU Water Framework Directive , the responsible state office NLWKN divided the Lutter into water bodies 15055 (upper reaches 1.6 kilometers in length) and 15054 (6.1 kilometers in length to the mouth) and assessed them in 2009. Here, too, the upper reaches are rated “good” in terms of chemical composition and the saprobic index, but the overall ecological condition is described as “unsatisfactory” due to considerable structural deficits. The water structure quality is only given the "V" rating in sections. The reasons for this are in some cases the lack of wood on the banks of the river, several falls and the continuously stretched course. In sections it also receives the grade “II”. The further course is assessed in a similar way, which scores a grade worse in terms of structural quality, but scores well in the other parameters despite the introduction from fertilized arable land. The data sheets contain a catalog of measures to improve the structure.
