John Grundy's Plan of the proposed Louth Navigation

Grundy Map

John Grundy an experienced drainage engineer from Spalding was approached by Louth Corporation in 1756 to survey the marshes and find the most feasible route for a navigation from Louth to the German Ocean.

His original survey has survived although it is now in urgent need of restoration, having faded considerably.

Apart from the elevations of the lock which can be clearly seen, the plan also shows how the area was farmed and managed before the enclosure act of 1805. All details of ownership are shown from the Mallards Ing (now Riverhead) up to the discharge into the Humber Estuary just past Tetney. Along with Brown's panorama this is one of the most important visual documents of Louth's history.

At the beginning of this year the Louth Navigation Trust, not having the resources to properly store and archive the survey, handed over the survey to the Lincolnshire Archives where it now awaits restoration.
