Overdiepse polder
In times of extreme high water, the Bergsche Maas is a threat to villages and towns along the river from Geertruidenberg to 's Hertogenbosch. Brabantse Delta Water Board, government and residents have worked together to create room for the river in the Overdiepse Polder to prevent flooding. The dikes on the north side of the polder have been lowered so that excess water can flow over them. On the south side, on the contrary, a new (winter) dike has been built to hold back the water. The eight farms in the polder have been placed on mounds. Thanks to the Overdiepse polder more than 4 million residents in the area keep dry feet.
