The Overdiepse Polder is one of the places where the river will be given more space. A special project because local polder residents and farmers already jointly sought information about this development during an early stage and they provided the final solution: the ‘dwelling mounds plan’ (terpenplan). A sustainable solution for safety and the agricultural use of the polder. The water from the river will flow through the polder every 25 years on average. This will lead to the high water level at the Bergsche Maas river dropping by approximately 27 cm where the Overdiepse Polder is located. You will still be able to notice this drop in the water level far upstream.
