Flood risk across Newham
Newham is bounded by the Thames to the south, the Lea to the west and the Roding to the east, and much of the borough — including the Royal Docks and Canning Town — is low-lying tidal floodplain protected by the Thames Barrier. Surface water is a significant risk too: the July 2021 storms flooded streets and homes across east London.
Flood zones only show river and sea flooding, and they ignore flood defences. Surface water and reservoir risk aren’t part of the zones – check them on the Environment Agency’s long-term flood risk service, or get the full report, which covers every source.
Rivers that shape local flood risk
Main rivers are managed by the Environment Agency. Smaller watercourses and drainage are the responsibility of Newham Council and landowners.
River Thames – The Royal Docks and North Woolwich
River Lea and Bow Creek – Stratford and Canning Town
River Roding – The eastern border with Barking
Channelsea River – Stratford
Who manages flood risk here
Newham Council is the Lead Local Flood Authority, responsible for surface water, groundwater and ordinary watercourses. The Environment Agency manages main rivers and the sea, and issues flood warnings. The same council also decides planning applications – and asks for a flood risk assessment in Flood Zones 2 and 3.
