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.

So that river users can plan their winter cruising and boat movements well in advance, the Environment Agency publishes the first issue of their programme of works in August each year.

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 customers can keep up to date. To receive this information, sign up to the email update service by emailing .
