Restoration of stream system
The Eelderdiep stream system, including the Runsloot and Stroetenloop, is important for water management in the Kop van Drenthe region. Due to interventions such as peat extraction, the straightening of streams, and water supply from the Noord-Willemskanaal, the system no longer functions naturally. This leads to problems in the water system:
Restoration and reinforcement of water system
To tackle the problems in the Runsloot and Stroetenloop water systems, the Noorderzijlvest Water Authority is implementing measures aimed at restoring and strengthening the water system.
Problems
Problems in the water system:
- Water drains too quickly during wet periods
- In summer, there is actually a water shortage.
- The ecological quality does not comply with the Water Framework Directive (WFD).
- There is a risk of the upper reaches drying up.
Measures
The measures focus on:
- Developing a natural and self-regulating stream valley and stream system
- Increasing the sponge effect so that water is better retained in the area
- Improving water quality by creating a more permanent flow and increasing the biodiversity of plants, aquatic animals, and fish.
Location

European Water Framework Directive (WFD)
In Europe, agreements have been made about clean and healthy water. These agreements are laid down in the Water Framework Directive (WFD). The aim is to improve the quality of streams, ditches, and other waterways.
For the Eelderdiep water system, this means that we will make the course of the Runsloot and Stroetenloop more natural. We will ensure that fish can live better in the lower reaches of these rivers. This will create a healthier living environment for plants and animals. These measures will also help to prevent the area from drying out.
Fishing for Connection
Groningen is one of the few provinces where streams flow into the sea. Waters such as the Reitdiep with all its upper reaches (Peizerdiep, Eelderdiep, Dwarsdiep) are crucial for migratory fish such as sea trout, eel, ide, and stickleback—which in turn are an important food source for Wadden Sea birds.
That is why measures are being taken throughout the entire route, from the Wadden Sea and Lauwersmeer to the upper reaches of the streams, to ensure ecological restoration. This also applies to the Runsloot and Stroetenloop.
The aim of the Vissen voor Verbinding (Fish for Connection ) project is to improve connections so that migratory fish can migrate between the sea and the waters behind it.
Northern Drenthe
This project is part of the Kop van Drenthe regional approach. Various organizations are working together in this area, which stretches from Fochteloërveen to De Onlanden. Together, we are making the landscape more resilient to climate change. More information Kop van Drenthe
The water board ensures good water distribution, more plants and animals, cleaner water, and a landscape that is better able to withstand drought and heavy rainfall. In this way, we are making the area stronger for the future.
