A polder is a diked, low-lying piece of land that is either used for land reclamation through drainage or, as in this case, serves as a flood protection retention area by being flooded when necessary to absorb water masses and protect the areas below. Description: Diked areas along rivers (here: the Rhine) that serve as retention basins. Purpose: During extreme floods, these areas are deliberately flooded to absorb water masses, reduce pressure on dikes downstream, and thus prevent flooding in low-lying areas (e.g., Rees). Function: Water is channeled into the polder in a controlled manner via locks or special overflow channels. Polders are separated from the water and the surrounding landscape by dikes. The principle is to create controllable bodies of water, either to reclaim land or, as in this case, to protect against the destructive power of flooding. (Source: Overview with AI)

The Bislich-Landesgrenze Dike Association, as a water and soil association, is planning the construction of the dike relocation and the Lohrwardt summer polder. This project will create an additional retention area of approximately 15 million square meters within a retention area of approximately 270 hectares. As part of the "ecological planning" for polder operation, the inlet structure is part of the continuous system spanning the Rhine, Lake Roosenhof, Lake Lohrwardt (= Grindsee), Reeser Altrhein, and the connection downstream to the Rhine. The entire system of inlet structure-culvert-outlet structure also serves to ensure fish passage in and out of the summer polder, including a fish trapping and monitoring station and a fully automated process control system for the water level and flow systems. Appropriate closure devices (dike gate, channel gate, and stop log closure) are planned for the "retention polder" operation scenario. When planning the inlet structure for the purpose of ecological flooding, the geometric, static, and visual aspects and dimensions, as well as the type of system and control technology, were adapted to the conditions already established in the pumping station, particularly for reasons of maintenance and operational safety.

Pumping stations are directly and indirectly required for the Bislich-Landgrenze Dike Association's area and the affected catchment areas (see also waterway maintenance) to ensure proper outflow in the landwehrs. The natural outflow at the pumping stations depends on the respective Rhine water level. This means that the Rhine water level must be below the outflowing water in the ditches and landwehrs. If this is not the case and the Rhine level is higher, the natural outflow is disrupted and not possible. To prevent Rhine water from entering the association's area, the floodgates are closed. Once the outflow is disrupted and natural outflow can no longer occur, for example, because the Rhine water level is higher than that of the landwehrs, water must be artificially pumped (drawn) from the hinterland into the Rhine using pumps. The relocation of the dikes results in changes in the sluice and groundwater conditions. In addition, the rerouting of some of the association's waterways and the reactivation of old water structures will be necessary, which will also impact existing water management conditions, necessitating the construction of the "Polder Lohrwardt" (PL) pumping station as part of the Lohrwardt dike relocation project.

Very nice cycle path with a view of the Rhine.

A really nice experience to watch the storks from a distance

Always nice to watch the storks in the nest

Beautiful river landscape on the left bank of the Lower Rhine – a link between nature and industry. The river serves as a transport route for essential raw materials and finished products on their way all over the world.
