Thames Area assets

In the Thames area we have a wide range of assets, including locks, weirs, flood defences, boat moorings and monitoring stations for air and water quality. Flood defences can include embankments, walls, flood gates and flood diversion channels. Our assets help to protect people, property, and the environment from flooding, drought and pollution.


We regularly receive enquiries about our work. This page will highlight the assets that we we receive the highest level of interest for. You will find asset information, frequently asked questions, and latest news. If you are interested in an asset not given here, please email our enquiries team.

To ensure you keep up to date about our most recent work for these sites, register with us and then subscribe to follow this page. Links to do this are in the information bar.

The Environment Agency can carry out maintenance, improvement, or construction work on main rivers to manage flood risk and protect the environment. This is done using our permissive powers under the Water Resources Act 1991. You can learn more about the Water Resources Act 1991 through this link. Any work we carry out using these powers is subject to available funding and resources.

Responsibility for maintaining main rivers ultimately remains with the riparian land owner. All watercourses not designated main river are ordinary watercourses and the Lead Local Flood Authority has similar permissive powers on these.

    Following a tree strike in 2023 an inspection of this 90 year old bridge highlighted significant safety risks caused by cracks within the cast iron structure and one of the bridge supports.

    Keeping the public safe is one of our highest priorities and we therefore closed Bridge 142 in February 2024.

    We have closed a section of the Thames path, just south of the Runnymede Bridge/ M25 bridge between the Runnymede Hotel and north of Staines. There is an alternative safe route in place.
