Planned lock closures: updated 15 March 2018
The Environment Agency carries out a programme of works on the River Thames every year between November 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 early August each year. Please see Issue 4 details below.
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 email@example.com.
Listed below are the locks that will be closed during the 2017 to 2018 investment programme. The locks will be closed from the first date listed and re-open on the day after the final date.

Know your river conditions
Any river activity poses a greater risk when there are strong currents, high river levels or cold weather conditions. River flows can increase even during the summer months – never assume sunny weather means the conditions are not hazardous.
Warning boards may be displayed at locks to inform river users of the conditions. Read the explanations of what these mean for you. Don’t take risks and never underestimate the power of the river.
When these red boards are displayed on lock gates, we advise users of all boats not to navigate because the strong flows make it difficult and dangerous.
People in hire boats arriving at a lock where these boards are displayed should stop immediately and contact their hire boat operator to ask for instructions.
When these yellow boards are displayed on lock gates, 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 further warning.
When these yellow boards are displayed on lock gates, we advise users of all unpowered boats not to navigate and users of powered boats to navigate with caution.
Dealing with changing river conditions
Read this section carefully to find out what to do if you find yourself in conditions where we advise you to stop navigating. Remember, not all conditions will be serious enough to require all the measures suggested below.
- Please take the advice to stop. Even the most experienced boater can be caught out, so think about those who could be put in danger if they have to help you.
- Moor your boat in a safe place, preferably in a marina or at a recognised mooring. Limited space may be available at some locks. Moor against high banks if you can.
- Ensure your mooring lines are fastened to secure fixings such as bollards, rings or even trees; put out extra lines for additional security and allow enough slack for a further rise in river levels; don’t rely on your own mooring pins or stakes, they might not hold.
- If possible, put extra fendering (eg scaffold poles or strong timber posts) between your boat and the bank side, to prevent your boat drifting onto the river bank and becoming caught up when levels drop.
- Make sure you have a safe exit ashore from your boat. If not, you should consider returning home or finding alternative accommodation until conditions improve.
- If you are running low on essential supplies or have other safety concerns and are not able to vacate your boat safely, treat this as an emergency and dial 999 to ask for evacuation.
- Those in hire boats: if you are advised to stop navigating, you should stop immediately and contact your hire boat operator and follow their instructions.
Please remember your life is more important than your boat
The Environment Agency does not provide emergency services and is not able to carry out search and rescue, or provide supplies to stranded boats.
