Welcome to the Environment Agency's online River Thames conditions update service which displays our current advice to river users. We display warning boards at our locks to inform river users of conditions that may make navigating difficult and dangerous.

This page shows our current advice for each reach of the river between Cricklade and Teddington. We will update this information regularly when warning boards are being displayed at locks and as river conditions change.

Information for boaters

Footbridge Closure

We will be temporarily closing Temple Footbridge (upstream of Temple Lock on the River Thames, near Marlow, Buckinghamshire) at 10am on Saturday 16 March 2019 in order to carry out further investigations of the timber bridge arch.  We aim to complete our investigations by Wednesday 20 March 2019, when we will update this message.  The bridge will remain closed throughout this period. We apologise for any inconvenience this may cause.

Navigation notice, fallen trees update

The fallen tree between Rushey and Radcot locks has now been removed.

We will update you with any news on the fallen tree between Shifford to Rushy locks as soon as we can.

Apologies for any inconvenience caused.

Location of the tree

River conditions and navigation

For water levels go to https://flood-warning-information.service.gov.uk/river-and-sea-levels 

For flow rates go to http://www.gaugemap.co.uk 

Navigation marks on shoals and underwater obstructions.

When navigating upstream, leave red buoys to the left and green buoys to the right. When navigating downstream remember that the opposite rule applies. Avoid yellow and orange buoys as they mark hazards. For further advice, ask the local duty Lock Keeper.

Annual registration

If you keep your boat anywhere on the non-tidal Thames (including in marinas) you need to register your boat and pay the annual fee or risk being prosecuted for non-compliance. Most boat owners pay for their licence on time.

Contact the boat registration team on 03708 506 506.

Speed limit

The speed limit for all vessels (except rowing coach boats training crews) on the non-tidal Thames is 8kph or 4.3kts or 5mph. Do not create wash whatever speed you are navigating at.

Key

Caution strong stream
We advise users of all boats not to navigate because the strong flows make it difficult and dangerous.
Caution stream increasing
We advise users of all unpowered boats not to navigate and users of powered boats to find a safe mooring. This is because river flows are likely to strengthen and red boards could be displayed very soon and without warning.
Caution stream decreasing
We advise users of all unpowered boats not to navigate and users of powered boats to navigate with caution.

Floodline

This information is also available on Floodline. Call 0345 988 1188 and select option 1 for river information for boaters.
