Water retention in the Dwingelderveld good for the region
As a result of climate change, we occasionally face heavy rainfall. For this reason, it is important to incorporate areas into the design where rainwater can be retained or temporarily stored. Engineering measures, such as heightening of dikes and the use of extra rubble, can no longer sufficiently protect the lower regions of our country from flooding. This is why we have to collect the water in designated areas. Even the Dwingelderveld can collect water if necessary. This ensures that the water does not have the chance to cause flooding downstream, so that towns such as those just south of the Dwingelderveld and Meppel remain safe from flooding. By means of an ingenious system, the Dwingelderveld is able to retain rainwater for a number of days. Very gradually, the water is then discharged into the Ruiner Aa. Thereafter, the water flows through Meppel towards the IJsselmeer.
The district water authority's entire catchment has a water plan. Nature and water storage or water retention often go well together. Under conditions of extreme precipitation, 1.25 million of cubic meters rainwater can be retained in the Dwingelderveld with little damage to the environment. This allows the Dwingelderveld to temporarily retain more water than the minimally required for this catchment area and this is beneficial to the area surrounding the Dwingelderveld. This also means that the district water authority doesn't have to impose any extra batters on the areas outside of the national park.
