Here you look at a historical location.
Historical interpretation: Zierikzee was besieged by the Spaniards in the 16th century, during the 80 years war. To make it more difficult for the Spaniards to conquer the city, Rev. Gerardus van Culemburgh set out with his consistory and a group of sailors and soldiers on October 3, 1575 to pierce the seawall at Borrendamme, south of Zierikzee. The Spanish general Cristóbal de Mondragón tried to close the gap, but the dike broke and almost the whole of Schouwen was flooded.
Zierikzee held out, although the population was severely affected by famine during the siege. When the Spaniards left the city in November 1576, the damage was enormous. Schouwen was under water and almost all residents on Duiveland had fled. Many houses and barns were destroyed or used as firewood. The recovery took many years and cost a fortune. First of all, the repair of the dikes was started, the sea water even threatened the city walls. After the repair of the dikes, the Kaaskenswater and the nearby Ronde Weel remained.
In most places the Kaaskenswater is one to three meters deep, but at 'De Schouwsedijk' it can be up to five meters deep.
Trout and eel swim in the water. The salt content is 3000 mg/l in winter and more than 9000 mg/l in summer. This is much too salty for freshwater fish. In the past people have tried to turn it off there, but that was never successful. The Kaaskenswater is a popular place among fishermen who fish for saltwater fish.
