Koedood was the name of a small stream, flowing from the Oude Maas northwest to the Nieuwe Maas, 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.[1]
The hamlet was formerly divided into two parts: "Oude Koedood" in the west[2] and "Nieuwe Koedood" in the east.[3]
