Water storage Volkerak-Zoommeer
Current situation
The Volkerak-Zoommeer (lake) is being prepared as a temporary storage site for river water during extreme situations. The water storage facility will provide protection for the southwest of the Netherlands in the event of storm surge barriers being closed in combination with very high discharge from the rivers - an exceptional combination. The likelihood of the Volkerak-Zoommeer water storage facility being utilized is 1/1,400 a year.
