Vieille Meuse
Koedood was the name of a small stream, flowing from the Oude Maas northwest to the Meuse River, opposite of Schiedam. It separated the island of IJsselmonde from Poortugaal and Rhoon. It was dammed and used for draining the surrounding polders. The hamlet was built near the southern end of the river, and consisted of six houses with 42 inhabitants around the middle of the 19th century.
