Important decision of the district water authority

On December 17, 2009, the Development plan and Water Decree Graben Structure Dwingelderveld were on the agenda of the General Board of the district water authority Reest and Wieden. The board definitively established the design. It took the submitted viewpoints and proposed plan changes into account.


The district water authority described the problems and solutions in a "Development plan and Water Decree Graben Structure”. Some citizens have suggested changes and expressed their concern about the waterlogging, complete with constructive suggestions. Handling all the remarks and considerations took longer than usual. This was due to, inter alia:

  • The decision of the Westerveld municipality regarding the Lhee Kraloo road.
  • The election of a new General Board Reest and Wieden.
  • The statutory testing of the plan due to the Environmental Protection Act. This required additional research.

Water retention

This has led to a number of changes in the plan, such as modifications to the quay route Kloosterveld and adjustments to the quay route and the construction of a pool on the Leisloot. Attention is also paid to existing water drainage Voor de Broeken. The district water authority is the advisory body in this matter. A plan is in the works to solve existing issues. As a result of the Nature Survey, no so-called V-notch weirs will be built in the Dwingelderveld, but special weirs will be constructed on the edges of the Dwingelderveld. This allows a large volume of water to be temporarily retained should excess rainfall occur. Once the peak flows out through the streams, the retained water is drained. This is comparable to the 'zippering' of cars on a freeway in order to avoid congestion. Water traffic, so to speak, often leads to wet feet in the stream valleys and in Meppel. In order to monitor the situation, the district water authority installs extra measuring points and the water level is also measured in the brook valley outside of the National Park. These measurements will be posted on the Reest and Wieden website shorty.

Major improvement

With the Water Decree, the district water authority largely resolves internal drought for the area of 2100 hectare. The water levels required to maintain and improve the nature come within reach. The administrators are responsible for other measures. If they were to convert the woods along the graben into heathland, the internal drought would be entirely (100%) resolved. Softwood consumes up to 75% of rainwater.



Stagnate - Retention - Discharge

As a result of climate change, it is essential to create space for water. Nature and water retention often go well together. In case of heavy rainfall, the Dwingelderveld is capable of retaining 1,25 million cubic meters of water with minimal damage to the environment. Under extreme circumstances, a few agricultural plots and the Bungalow Park on the Leisloot are faced with waterlogging. The solution is to design an overflow area on the north side of the Leisloot in the site of Natuurmonumenten. Measures for doing so are part of the Dwingelderveld development plan.

Anserveld and Moraine

In 2012, the drafting of a Water Decree for the Anserveld and the agricultural area Spier Moraine was undertaken. The agricultural area Spier Morain drains part of the excess agricultural water via the Dwingelderveld. An alternative solution for this is being considered. We begin with an initial meeting in the area in which we inventory requests and problems. During the meeting, the district water authority presents a plan of action. In Anserveld, there are a number of extra possibilities for water storage during extreme precipitation.
