The building of the Ripon Canal was authorised by an
Act of Parliament passed on 15 April 1767, and the canal was the final part of a larger plan to upgrade the
River Ure from its junction with the
River Swale to Oxclose, where the canal would leave the river and head for Ripon, some away. Below the Swale the Ure becomes the
River Ouse, and so carriage of goods to and from
York and
Hull would be possible. The estimated cost of the whole project was £9,000, and the Act established Commissioners, who could borrow money in order to fund the development although the total amount of money to be borrowed was not regulated by the Act. The works were designed to allow the passage of
keels, which were . Work started first on the lower sections, which were progressively opened from 1767. The canal route was surveyed by
William Jessop and work on its construction started in 1770, with Jessop acting as Engineer, supervised by
John Smeaton. The engineer overseeing the day-to-day operation was John Smith, and a masonry contractor from Halifax called Joshua Wilson was also employed. Construction was completed in early 1773, at a cost of £16,400, and regular services between Ripon and York started in February. The canal was fed with water by a feeder that left the Rivers Laver and
Skell in Ripon. The original Commissioners had ceased to function, and so a group of creditors formed
"The Company of Proprietors of the River Ure Navigation to Ripon", and obtained a second Act of Parliament on 23 June 1820, which gave them powers to raise £34,000 by the issuing of shares, with an extra £3,400 if needed. They were required to spend £3,000 on repairs within five years of the Act being issued. Improvements were made, both as a result of the Act and separately in 1838, which resulted in larger boats being able to negotiate the canal. Payloads increased from 30 tonnes in 1822 to 70 tonnes in the 1840s, when the navigation could accommodate boats drawing all the way to Ripon. It was never able to handle the Humber sloops, which ran as far as Boroughbridge, with their width of and draught of . Despite the railway from Darlington to York opening on 4 January 1841, which provided a way to bring coal from the Durham Coalfields south to York, the
Aire and Calder Canal were shipping around 26,931 tonnes of coal per year along the Ure Navigation at the time, and the Company of Proprietors was making profits of £886 on an income of £2,013. Some of this traffic stopped at Boroughbridge on the River Ure but a good proportion passed along the canal to Ripon. ==Decline==
