set of tidal gates (at the entrance from the Welland).  There are no locks.

Waterway notes

Maximum Boat Sizes

  • Length: Unlimited, but craft over 30 foot (9.1 metres) will have difficulty in turning.
  • Width: 14′ 6″ (4.4 metres) – Surfleet End Sluice
  • Headroom: 6′ (1.8 metres) above ordinary summer water level at Sluice Bridge
  • Draught: 3′ (0.9 metres) at Surfleet, but reducing nearer to Tongue End

Navigation Notes

  • Entrance to the River Glen depends on the state of the tide on the River Welland.  The tidal gates are only available when the tidal river Welland is at the same level as the Glen.
  • The junction with the Bourne Eau is the only turning point above Pinchbeck Bars Bridge (a distance of 5 miles – 8km).  Small craft may be able to proceed further upstream, but there is no turning.

Navigation Authority


There is a towpath for the whole length of the navigable river Glen, and beyond Tongue End as far the A15 road bridge.  The entire towpath forms part of the Macmillan Way, a continuous signed 290 miles (467 km) long-distance path running from Boston to Abbotsbury on the Dorset coast.

Waterway news

Waterway underfunding

Hundreds of miles of waterways – along with their unique heritage and habitats – are currently starved of funding and rely on constant lobbying by us to safeguard their future.

Sustainable Boating

We want boating on canals and rivers to be more sustainable and – even though the current overall contribution to UK carbon emissions is very small – we want to help reduce emissions on the waterways.

Waterways Heritage at Risk

Britain’s canals and rivers are a unique, living heritage. But that heritage is at risk – from urban development, lack of protection, loss of skills and knowledge and climate change.

You can help Save Waterways Heritage.

Waterway restoration

Restoring the UK’s blue infrastructure – our inherited network of navigable canals and rivers – is good for people and places.
