Anglian waterways: river conditions, closures and restrictions

Strong stream advice, river conditions, reach closures and restrictions affecting boaters on Anglian waterways.

Strong Stream Advice

The Environment Agency issues Strong Stream Advice (SSA) to inform river users when river levels are increasing and when locks are being prepared to discharge flood water. Notice boards, flags and lights are displayed prominently on riverbanks to inform boaters of the status of the river and red flags are also raised at several boat clubs. Environment Agency currently issue SSA on the River Ancholme, River Nene and River Great Ouse (Bedford Ouse).

River closures and restrictions

We also offer an online shared calendar that provides up to date information on river conditions for boating on Anglian Waterways. This and our other river calendars can be accessed on our Northampton Marina website via Although this shouldn’t be a replacement for registering your details with us to receive river advice for boaters, you may find it useful and you can refer back to it regularly and create a subscription to get notifications sent in a way that you want, when you want.


For more information email or call our National Customer Call Centre on 03708 506 506.
