River conditions

Current condition on the River Medway:

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.
