Construction of Lauwersmeerdijk tidal culvert marks start of unique nature projects
On Monday, June 3, construction began on a dyke passage in the Wadden Sea dyke near Lauwersoog. Collaborating parties jointly gave the go-ahead for construction on the sea dyke, thereby launching the implementation of the nature projects for the Lauwersmeer-Vierhuizergat dyke reinforcement. The projects will improve the ecological water quality and nature of the Wadden Sea. In addition to the dike passage, this involves a tidal area in the Marnewaard, artificial reefs and tidal pools, and the development of natural salt marshes.
On Saturday, June 8, there will be an open house where interested parties can take a look at the construction of the dike passage.
Attendees at the launch of the nature projects
Annette van Velde, portfolio holder at Noorderzijlvest Water Authority: “In 2023, work began on reinforcing the dike. It's wonderful that we can now also start implementing the nature projects! Together with government agencies, nature organizations, and the Ministry of Defense, we have developed these nature projects for a healthy Wadden Sea ecosystem and a strong dike. Together with the market, we are reinforcing the dike with significantly lower emissions and smart (re)use of raw materials. In this way, we are building the most sustainable dike in the Netherlands. I cordially invite everyone to come and see for themselves during Construction Day on Saturday, June 8.
Linda-Rose Santhagens, director of Rijkswaterstaat North Netherlands: "This Lauwersmeerdijk-Vierhuizergat project shows that it can be done! It is a wonderful combination of dike reinforcement and nature development in the Marnewaard and along the edges of the Wadden Sea. The 70 hectares of intertidal area being created here is truly unique in its kind and size. I am therefore proud that it has come this far, thanks in part to the commitment and conviction of all the partners involved!"
Susan Top, deputy for the province of Groningen: "In this special part of the Netherlands, the dyke reinforcement, which is necessary for water safety, offers an opportunity to link nature projects to it. We have worked hard with all those involved to make this possible. In this way, we are taking steps together in the development of a coast that is future-proof and also provides unique nature."
What are the nature projects?
Over the next three years, dike workers will also be working to make the transition between land, mudflats, and water more natural by constructing:
- Marnewaard tidal area: we are constructing a dike passage and tidal area in the Marnewaard.
- Artificial reefs and tidal pools: we are constructing an artificial reef along the dike and creating tidal pools at the foot of the dike. This will make the transition between the mudflats and the dike more natural.
- Natural salt marsh development: we are creating a natural salt marsh along the dike near the Westpolder.
The implementation of the nature projects will take around three years and will be completed at the same time as the dike reinforcement.
Dike reinforcement
Reinforcement of the dike is necessary because it no longer meets water safety standards. Once the work is complete, the dike will once again protect against higher sea levels and extreme weather caused by climate change for the next 50 years. The dike reinforcement is part of the national Flood Protection Program (HWBP) and thus the national Delta Program.

Open house Saturday, June 8
Saturday, June 8, is Construction Day, when visitors can visit the Marnewaard dike passage construction site. There will also be all kinds of activities in the harbor and at the dike information center, offering a glimpse into the construction of our dike of tomorrow. The open house is from 10:00 a.m. to 4:00 p.m. at the Dike Information Center, harbor 46C Lauwersoog.
