The dredging works are taking place through a joint partnership with the Trust and Grantham Canal Society, with funding made possible thanks to the People's Postcode Lottery.
The project complements a separate scheme, funded by the Heritage Lottery Fund to restore two locks on the canal. Works on Lock 15 were completed last year with volunteers taking it apart, piece by piece, after its 200 year old walls deteriorated. The volunteers laid new foundations, completely rebuilt the lock walls and created new lock moorings.
Much of the material removed from the canal as part of the dredging project is set to be re-used in the landscaping around Lock 15.
The canal was opened in 1797 as a cost effective way of transporting coal from Nottingham to Grantham. It proved prosperous until the opening of the Grantham to Nottingham railway in 1850. Unable to compete with the railway the canal eventually closed to boats in 1929 and over time the locks fell into dereliction.
Since the 1970s volunteers have been working, from the Grantham end, to reverse the decline and around four miles of the canal is navigable to boats between Woolsthorpe and the A1.
Karen Rice, project manager for the Trust, said: “It's an incredibly exciting period in the canal's long history, with the restoration of the two locks, there's a real sense of momentum. If people want to get involved and play their part in the restoration of this fantastic canal we'd love to hear from them.”
David Lyneham-Brown, chief executive officer of the Grantham Canal Society, said: “When this section is fully dredged it will add two locks and over half a mile to the navigable eastern end of the canal – another major step in the restoration process. It would be fantastic to see more people join us in this latest endeavour.”
