The River Rom, also known as the River Beam below its confluence with the Ravensbourne, is a tributary of the River Thames in England that flows through east London suburbs surrounding the metropolitan centre of Romford, forming the boundary between the London boroughs of Barking and Dagenham and Havering. The Rom is culverted for a brief midsection as it passes through the centre of Romford.
At this Geocache River rom is protected by fence and concrete column with bolts and nuts, they are well fixed and cannot be cross!
