Lutter (Lachte)

Lutter at Bargfeld, from left opens out the narrow water

The Lutter is an approximately 26 km long, semi-natural heath brook on the eastern edge of the Nature Park South Heath, a tributary of the Laughed. Your source is located near the B191 north of Weyhausen in the district of Celle.

Course

The Lutter predominantly flows in a southerly direction, increases from left to the Ahrbeck and first reaches Marwede. On their way further to the south reaches the Lutter Bargfeld. This flows to the narrow water from the left. Behind Bargfeld leads a largely channeled Köttelbeck. The Lutter then flows in a southwesterly direction to Eldingen passing through the village Luttern and flows north of Jarnsen at Lachendorf in the Laughed. The Lutter exceeds Laughed here to water flow and length, is hydrologically So the main strand of the river system of Laughed dar.

Use of the water body

In Marwede is a former water mill, which was first mentioned in 1438 at this location. Approximately 1687 to 1954 operated the Miller family Wolf Hagen this mill. It was driven by hydropower have a grain mill, a saw mill and an oil mill with a pug mill. In 1796 a fire destroyed the building. 1906, the water wheels were replaced by a turbine. In the 1960s, the mill was shut down. She is now a protected monument.

Since acquiring the mill in Eldingen, in the context of large-scale conservation project Lutter in 1992, the mill pond is no longer discharged. In order that no fine sediment comes to lying underneath the course more in the Lutter. In 2000, the dam was removed and expanded the turbine. The mill lost her jam law. The ecological permeability of Lutter has been restored and created a prerequisite for the successful development of the conservation project.

Reserves

Virtually the entire Talung the Lutter and the narrow water, Köttelbeck and some other tributary streams are protected and form the 2435.3 -acre nature reserve Lutter. This is part of a total of 5113 hectares of the FFH area " Lutter, Laughed, Aschau ( with some side streams ) " and bordered by the mouth of Lutter at the nature reserve Laughed.

The run is the Lutter, on the lower reaches marginal, South Heath Nature Park, which does not apply to the entire nature reserve.

Fauna and Flora

The area is a semi-natural area of ​​South Heath for conservation of particular importance. Not only the streams itself as a habitat of fish and otters, but also the adjacent floodplain and swamp forests, bogs, swamps and source areas where bird species such as the black stork, eagles, cranes, kingfishers and rare riverine dragonflies, such as, inter alia, the endangered scarlet Dragonfly and the highly endangered small blue arrow are native.

More than 160 endangered animal and plant species live and in these heathen streams. Of particular importance here is one of the last occurrence of the freshwater pearl mussel ( Margaritifera margaritifera ). The place particularly high demands on the quality of their habitat. Through a large-scale conservation project successes in the conservation of freshwater pearl mussel has been made. The stock listed above, the only one in the whole of Europe, a positive development. In initial experiments in 1985 captured brook trout were in the Lutter infected with freshwater pearl mussel larvae and returned to the stream. However, these initial measures were initially without success. The cause lay in the unnaturally high sand load of Lutter, a thing you later found and eliminated as part of the conservation project. The scientific substantiation by Buddensiek ( 1991) and the confirmation in practice by Abendroth (1993 ) led to the breakthrough. In 2008, more than 12,000 shells were detected again ( in the 1930s lived in Laughed and Lutter still about 50,000 copies).

Nature conservation project

The Federal Agency for Nature Conservation, the State of Lower Saxony as well as the districts of Celle and Gifhorn promoted the nature conservation project " Lutter " 1989-2006 financially with 16.5 million euros. The federal government contributed 75 % in this case, the state of Lower Saxony 15%, and the districts of Celle and Gifhorn 10 % of the cost. An important measures were carried out:

• Purchase almost all floodplains, tributaries and marshes from which water enters the Lutter,
• Rewetting of Moore,
• Features of the trenches with sand traps,
• Purchase of storage rights of mill weirs and degradation of the weirs,
• Construction of Sohlgleiten to the still existing weirs,
• Mill ponds are not drained.

Name

The name is Low German Lutter and related to the appellative "louder", which is in Middle High German for loud, bright, pure, clean. Lutter is a common river or stream name, but also occurs in derived place names. The same significance is louder in fixed expressions yet received ( eg, a " fair character ").
