Fens Waterways Link

The Environment Agency has obtained a "significant proportion" of the £8m required for phase one. Starting from the north, the first development was the provision of a new tidal lock from the Haven in Boston to the South Forty-Foot Drain at the Black Sluice, opened to traffic on 20 March 2009.[2] Funding for phase two of the project, which will involve widening of the South Forty-Foot Drain from Donington to a new road crossing under the A151 road, a new lock and a junction with the River Glen, a tributary of the River Welland, at Guthram Gowt has been secured from the East Midlands Development Agency.[3]

To connect the Glen to the Welland requires a new tidal lock at the Surfleet Sluices and reconstruction of the tidal Fulney Lock in the River Welland, leading to Spalding.

Another major innovation will be a new cut between the Welland, probably at Peakirk and the River Nene downstream of Peterborough, costing at least £20m and probably using the Folly River and part of either Car Dyke or Cat's Water Drain, entering the Nene near Flag Fen. From here the link will follow the existing Middle Levels through Whittlesey Dyke, King's Dyke and Vermuyden's Drain (Forty Foot Drain) to Chatteris. To avoid the existing troublesome crossing from Salter's Lode to Denver Lock a new lock would probably be provided from Vermuyden's Drain into the Old Bedford River at Welches Dam, and thence to the Great Ouse at Earith, though another possibility is to use Fenton's Lode to avoid most of the tidal section.[4]

The completion of the project would be the long-discussed Bedford and Milton Keynes Waterway canal between Bedford and Milton Keynes following the course of the Great Ouse and joining the Grand Union Canal, mooted as the "first new canal in over a century". The funding for this is slowly appearing and as well as providing for the first time an inland route for broader boats—up to 3.2 metres (10 ft 6 in) wide—between the north and south of England, it would also serve as a flood relief channel for new developments in the areas through which it is to pass through. This extra benefit may release funding from wider sources.[5] Adaptation of existing locks and bridges would be necessary to increase the dimensions to Grand Union Canal gauge, both in width and air draft.

  Proposed route
• 
  Black Sluice Lock, where the South Forty-Foot Drain joins The Haven at Boston
• 
  The South Forty-Foot Drain at Pointon, between Boston and Guthram Gowt. Here its origin as a drainage channel, set below the level of the surrounding fields, is very evident
• 
  Guthram Gowt. The location of the planned lock into the Glen is probably somewhere in this photograph.
• 
  The water level in the River Glen, here pictured looking west towards Guthram Gowt, is maintained by a tidal sluice at Surfleet Seas End. The sluice will be replaced by a lock
• 
  This section of the Car Dyke, near Eye, will be restored to navigation as part of the Link if problems of culverting under modern road improvements can be solved
• 
  The Cat's Water Drain is under consideration as an alternative route should the Car Dyke prove unsuitable
• 
  The Forty Foot Navigation, 1997. A new cut to bypass this shallow section may be constructed
• 
  The Forty Foot Navigation at Welches Dam on the Old Bedford River. The lock was restored in 1991
• 
  The route along Well Creek crosses the Mullicourt Aqueduct above the Middle Level Drain
