Notices and stoppages
If you're planning a boat journey, or going for a walk or ride along our towpaths, it's a good idea to check if there are any closures or works affecting your route before you leave home.
To travel through some tunnels, bridges and locks you will need to book passage in advance. This might be because of unexpected events, such as an unplanned stoppage or coronavirus restrictions, or because boat passage needs to coincide with tide times.
Search for any closures (stoppages), restrictions and booking information, opening times, notices and navigation advice. Simply enter the first two letters of the waterway you’re interested in. Then filter by type of notice and view notices either in a list or on the map.
Any stoppages on our network relating to coronavirus restrictions will be listed on this page. However, if you'd like more general information about how we're reacting to the pandemic and how we're supporting those who rely on our network, you can read our latest statement.

Winter works programme 2021/22
Each winter, when fewer boats are cruising our waterways, we carry out essential repairs and maintenance. In many cases we need to close the waterway completely, and sometimes even the towpath.
Before we begin we always consult the people who use our waterways to make sure these stoppages cause as little disruption as possible.
Thank you to all those who commented on our draft winter 2021/22 programme. This has now been finalised and you can see the individual stoppages in the main search below. You can also download a full list of the 2021/22 winter stoppages.
Please remember that all planned stoppages are subject to change, depending on the latest advice from the government regarding the coronavirus epidemic. We will update the notices to reflect any such changes.
However you use the waterways, please be aware of and considerate to other users. Read and follow our waterway code for boaters, anglers and unpowered craft and our Towpath Code for everyone using the towpaths.
Download a PDF of your waterway, for navigation information and boaters’ facilities. Note: some information may not be up-to-date, so cross reference with other available guides.
Check the dimensions of our waterways before setting off on your journey. Note: this information is only a helpful guide. Always use your own judgement and check water levels and other navigation advice first.
