Navigation on the River Thames may be restricted or closed in certain areas. Find out where and when these restrictions and closures are.
Boating by all types of vessel can resume on the non-tidal River Thames. We have completed surveys of every reach, marking all identified obstructions in the main navigation channel.
All locks are self-service until further notice. Public power functionality has been restored at all locks that have it installed (Godstow to Molesey except Blakes).
Before boating on the River Thames, you should check the current river conditions.

Planned lock closures
The Environment Agency carries out a programme of works on the River Thames every year between October and Easter. This often results in the closure of a number of locks for relatively long periods.
The Environment Agency publishes the first issue of the programme in August each year. This is so that river users can plan their winter cruising and boat movements well in advance.
This programme of work is subject to change, due to weather and other circumstances. Revised issues of the programme of works are published throughout the winter, so river users can keep up to date. To receive this information, sign up to the email update service.
