River Medway: conditions, closures and restrictions

River conditions, reach closures and restrictions affecting boaters on the River Medway.

River conditions

Current condition on the River Medway:

Green: all clear (effective from 11am 27 March 2018).

What the conditions mean

  • Red: strong stream. We advise users of all boats not to navigate because the strong flows make it difficult and dangerous.
  • Green: all clear. No stream warnings are in force, all boats can navigate the river freely.

This web page will only be updated during business hours (Monday to Friday, 9am to 5pm). Outside these hours, customers should call Allington Lock on 01622 752864 for the latest stream information.

River closures

There are currently no unplanned closures on the River Medway. See planned lock closures and river draining for 2018.

When Where What’s happening
Monday 9 April 2018 and Thursday 26 April 2018 East Peckham Railway Bridge Following the works on East Peckham Railway Bridge in Winter 2017, contractors are returning to complete works. There will be a 4x4 meter floating pontoon with a scaffold tower erected onto the pontoon and covered with terram to catch any potential debris falling during preparation and painting operations. The pontoon will be moved out of the way when contractors are not working and can be moved to allow navigation to pass but please proceed with caution and allow time for contractors to move. The planned working times are: (day shift) Monday 9 April to Saturday 14 April 7am to 5pm, Saturday 14 April 10pm continuous to Monday 16 April 5am, (day shift) Monday 16 April to Friday 20 April 7am to 5pm, (nightshift) Monday 16 April to Thursday 19 April 10pm to 5am, (day shift) Monday 23 April to Friday 27 April 7am to 5am, (nightshift) Monday 23 April to Thursday 26 April 10pm to 5am
on or after 17 April 2018 Hampstead Lock - Sluice Weir Lock Navigation will be temporarily lowered due to an unforeseen issue with the operation of Anchor Sluice which requires urgent attention. We do not anticipate that the work will take more than one day and we will reopen the river as soon as possible. During this time no navigation will be possible in this pen and we will be temporarily closing Hampstead Lock and Sluice Weir Lock. The river level lowering will be subject to suitable river and weather conditions, and may be postponed if the conditions are not suitable.

Planned lock closures

There are no current planned closures on the River Medway.
