Stamford Canal

Stamford Canal, now disused, is one of the earliest post-Roman canals in England. It opened in 1670, around 100 years before the start of the Industrial Revolution which brought about the "golden age" for canals in Britain. Parts of the route can be traced on the ground, though only one lock survives intact. It was part of the Welland Navigation in Lincolnshire. First authorised in 1571, during the reign of Elizabeth I, construction did not start until 1664, under powers granted in 1620 and ratified by James I. It ran for 9.5 miles (15.3 km) from Stamford to Market Deeping and had 12 locks, two of which were on the river section at Deeping St James. No plans of its construction survive, although one of the locks was documented by a visiting water engineer in 1699. It contributed to the wealth of Stamford, allowing barley to be transported to the town for malting.

Plans to link it westwards to the Oakham Canal, northwards to the South Forty-Foot Drain and southwards to the River Nene in 1809 came to nothing, and it closed in 1863, soon after the arrival of the Midland Railway in the area. Although Stamford Corporation attempted to sell it after closure, its ownership was disputed, and they were unable to do so. Its course and some of its structures can still be traced in the landscape. These include warehouses at the terminus in Stamford, and a weir which regulated water levels on the River Gwash, which it crossed on the level.

The River Welland was one of the earlier on which improvements, in this case to allow navigation to Stamford, were authorised by an act of Parliament. The Welland Navigation Act 1571 (13 Eliz. 1. c. 1) was granted in the reign of Queen Elizabeth I in 1571, and the preamble explained how Stamford had prospered as a result of the river, but also stated that mills built between Stamford and Deeping had resulted in it no longer being navigable, as they had diverted the water. Powers were granted to restore the river using either the old channel or the new one, although it is not clear exactly what was meant by this. There is no evidence that any work was carried out under the terms of the act.

However, the powers were revived in 1620, when Stamford Corporation was given permission by the Commission of Sewers to build a new artificial cut, which would run from the eastern edge of Stamford near Hudd's Mill, to Market Deeping, where it would rejoin the river. The corporation estimated that it would cost £2,000 to carry out the work, and the act enabled them to charge tolls for its use, set initially at three pence (1.25 p) per lock, which could be charged once the work was completed. The decision was ratified in 1623 by a grant of James I, and the corporation expected to have the work completed by 1627. However, they were unable to find a suitable contractor to carry out the work, and failed to reach agreement on terms with David Cecil in 1636, and two other potential contractors after that. Nothing happened until 1664, when an Alderman from Stamford called Daniel Wigmore took the job. He built the cut and 12 locks, which included the High Lock and the Low Lock on the river at Deeping St James, at a cost of £5,000. In return for his expenditure, he was given the lease of the tolls for the next 80 years, for which he paid a rent of one shilling (five pence). The cut was the longest canal with locks in the country, when it was opened in 1670. Its construction preceded the 'canal age' by around 100 years, making it one of England's earliest post-Roman canals.

There are no known contemporary documents describing the design or methods of construction of the canal and nothing about its opening. However, a report from 1632 on alterations to the river noted that 600 men were involved in the work, so presumably there was sufficient labour locally for such tasks. Wigmore probably used handbills at local inns to recruit his workers, since there were no newspapers to carry advertisements. The work would have been done using pickaxes, shovels and wheelbarrows. The excavated ditch was then lined with blue clay to make it watertight. Excavations for a sewer in 1974 and work on a rubbish tip in 1979 revealed the layers of blue clay, and there were clay pits near Stamford, which supported a pottery industry, although their precise location is unknown.

The canal enabled goods to reach Stamford from The Wash, which was 34 miles (55 km) away, by way of Spalding and Crowland. The lower 24.4 miles (39.3 km) used the course of the Welland, after which the two river locks and weirs at Deeping St James were encountered. Beyond Market Deeping, the course consisted of an artificial cut with 10 more locks, by which it reached the eastern edge of Stamford, after which it rejoined the river to reach the town wharf. The length of the cut was 6.5 miles (10.5 km), although the length of the canal is usually quoted as 9.5 miles (15.3 km), to include the improved river sections at both ends. Just below Stamford, the canal crossed the River Gwash on the level. There was a weir on a bypass channel and a sluice on the main river channel, which enabled the river levels to be controlled, so that barges could cross.

Trade thrived, for Richard Blome recorded the prosperous Stamford malt trade in 1673, which depended on barley being carried by boat. With the death of Daniel Wigmore, his son-in-law Charles Halford became the owner of the toll rights. In 1695, he was receiving between £400 and £500 per year, most of it derived from the carriage of sea coal. The trade amounted to 3,000 chaldrons that year, and he tried to get the tax on sea coal, which Parliament had approved, reversed. He did not succeed, and failed again in 1706, by which time he stated that the tax had decreased the amount of coal carried to just 500 chaldrons. Besides coal, the canal carried malt and agricultural produce, groceries, timber, slate and stone. Boats used on the canal were small lighters, 35 feet (11 m) long by around 7 feet (2.1 m) wide, capable of carrying from seven to fourteen tons, and normally worked in trains of four vessels.

Although there are no known records from the time the canal was constructed, the lock at Hudd's Mill was documented by Thomas Surbey in 1699. Surbey was a water engineer, and made notes and drawings when he visited it, during a journey from London to York. The lock chamber was 86 feet (26.2 m) long and 11 feet (3.4 m) wide. The gates were hung on stone piers, but the banks between them were of earth. The gates were conventional 'V' gates, similar to modern ones, which included some sort of paddle, but did not include balance beams. Instead, a chain or rope was attached to the mid-stream edge of the gate and to the bank. While this would have made opening the gates possible, it is not obvious how they were shut. The measurements match those of the surviving structures, with the exception of Briggin's lock, which appears to only be 56 feet (17 m) long. There is no visible evidence that it was shortened at some point, nor any obvious reason why it would have been built shorter than all the others.
