The Ladenbek is a brook in the south-east of Hamburg that flows through the Boberger Niederung nature reserve and flows into the Bille there .
The Ladenbek was once a small source brook, which rises from a wet meadow between today's Weberade and Grandkoppel streets and turned from the Geest slope through dry areas on the Moosberg, before soon flowing into the Bille .
development
The natural water supply was steadily decreasing due to the increasing sealing of the soil through development in its spring catchment area , the upper Lohbrügge . However, since more rainwater had to be drained off due to the increasing development, a rainwater retention basin was built north of Bergedorfer Straße ( Bundesstraße 5 ) and the Ladenbek was moved into a straight concrete channel.
Because the channel was concreted, the insects and plants on the water could not adapt, the balance was disturbed. Furthermore, the water balance in the Boberger Niederung was disturbed, as no water could seep away.
Therefore, in 1987, the concrete channel in the area of the Boberger Niederung was removed again in order to achieve that the course of the stream becomes more natural and animals and plants can settle better. In addition, an infiltration pond was created in the upper third so that the surrounding area can also benefit more from the surface water. In a further step, the rain retention basin was also brought into a state that is more adapted to nature.
Shortly after the bridge over the Ladenbek on the Walter Hammer hiking trail named after Walter Hösterey , a fitness trail started in the 1970s . These devices for health prevention have since been abandoned and dismantled.
