Between 1801 and 1812, over £20,000 was spent on the canal, which included scouring the basin at Coalisland, building wharves, stores and boundary walls around it, rebuilding of lock walls and floors, dredging the whole canal to give a depth of 4 feet , repairs to lock houses, puddling of the lower reaches where it passed through peat, and upgrading of the towpaths.
