Rivers Welland and Glen locks

There are 2 locks on the Rivers Welland and Glen. They are both staffed by the Environment Agency:

  • Fulney Lock in Spalding, which marks the boundary between the non-tidal (or freshwater) River Welland with the tidal Welland
  • Surfleet Sluice, which connects the River Glen to the River Welland

The river is tidal beyond Surfleet Seas End - only experienced sailors and boaters should go through this sluice and into the Wash.

You must not operate these locks yourself.

Call the River Inspector before you arrive on 07721 390128, or call the Environment Agency on 03708 506 506 (find out about call charges).

Lock dimensions

Typically the locks on the Rivers Welland and Glen are 26m long and 4.6m wide.

Distances between locks

Distances and times between each lock based on the speed limit of 7mph and assumes that you will take 20 minutes to pass through each lock.
