District and Dijk Manager

Rayon manager and dike keeper Albert Kiers, works for Wetterskp Fryslân. He tells us about the inner and outer dike area on Terschelling. The island is slightly tilted: part is above NAP and part below. Kiers is constantly looking for the right water level for the whole area.
