This flag was adopted by municipal resolution on 20 Mar 1962. The colors
and lozenges have been derived from the municipal arms; the color yellow
symbolizes the important rôle of water in this municipality. The
placement of the lozenges reminds of the position between the rivers "Oude
Maas" and "Oude Waal".
