The River Slea begins as a patch of marshy ground to the west of Sleaford in Lincolnshire. It runs through Sleaford and eventually meets up with the River Withim which flows south to Boston and the Wash. In 1792 work began to convert the River Slea into a 'Navigation' to carry goods from Sleaford to Boston via a junction with the already navigable River Withim at Chapel Hill.

Restoration has now begun on the derelict locks and silted waterway to bring boats back to the Slea. ArtsNK for Sleaford and North Kesteven District Council commissioned Ian to walk the fifteen miles of a proposed riverside walk along the bank of the Slea Navigation, from its junction with the Witham at Chapel Hill to the centre of Sleaford. The result was to capture the modern reality of the watercourse in a series of ten consecutive prints.

The prints have been reproduced onto interpretation boards and sited along the riverbank at the points at which the sketches were drawn.
