The The Ravensbourne is a watercourse in the London Borough of Havering . It arises north of Ardleigh Green and flows south. At Hornchurch it turns west and flows into a lake in Harrow Lodge Park, from which it is drained underground. It comes to the west of the Upper Rainham Road ( A125 road ) again to the surface and shortly thereafter flows into the River Rom .
