Suspension of Navigation Notices.

Any confirmed upcoming suspensions or closures to navigation will be published on this page and via @MLC1862 on X and our Facebook page. You can also sign-up to receive a text message alert. Emergency closures will also be posted. Our News page includes navigation news items.

• If you are planning to enter or exit the Middle Level navigation via Stanground Lock or Salters Lode Lock, the Environment Agency have set up online calendars to host the latest navigation closures, restrictions and/or advisory notices on the Great Ouse (inc. Tidal Gt Ouse crossing) and Nene

Planned Suspensions for 2026 and 2027

The following are planned suspensions to navigation in 2026 and 2027. Once date windows are confirmed a suspension notice will be published and distributed.

• Ashline Lock – Closure likely during Autumn/Winter 2026/27 to de-water the lock and inspect the structure to inform future gas replacement and associated works. This would suspend the Nene – Gt Ouse link route.
• Lodes End Lock & navigation to the west of the lock – Two closures in Spring 2027 to enable the safe removal and return of the fourth of six pumps at Bevill’s Leam Pumping Station.
