We hope that more data on the early tonnages will
come to light as more research is undertaken.
The continual decline in tonnage presumably came about as the rail
network became more extensive and more reliable. However, it should
be noted that the railways came to Louth in the 1840s and that even
in the 1890s a considerable amount of trade was carried on using the
Navigation. Hardly an overnight collapse in canal use.

Tonnage out is a different matter. By the time these tables
commence, cotton had become the great rival to wool & the Lancashire
& Yorkshire cotton mills were fully operational. This may have had
economic repercussions for Lincolnshire which had drawn a lot of its
wealth since the13th century from the sale of wool. Louth never
became an industrial town as it was not near to any coalfields.
