Current survey areas Water Board Rivierenland

Within the Riverland water board, leveling areas are used. A level area is a water management unit where the same water level prevails. This level can be regulated by a pump or a weir. Current reference areas are those for which both polling and borders are laid down in the polling decision. These are adjusted by updating the standard decision, which happens once every ten years. The maps show the summer and winter levels per level area. The value 999.99 indicates that a min max bandwidth is used instead of a summer or winter level. These values will follow later.
