Cromford Canal - Origins

Origins

At the end of the eighteenth century an extension was proposed to the Erewash Canal by various interested parties who wished to encourage coal mining further north. The suggestion was declined by the canal company, so local businessmen, including Joseph Outram, the father of Benjamin decided to go ahead on their own, asking William Jessop to design one between Langley Mill and Cromford, with a branch to Pinxton. This would carry coal to Cromford, which was becoming industrialised, and limestone from the area for the growing iron industry. Also important would be lead from Wirksworth and cotton from the Cromford mills. The connection to the Erewash Canal would provide an outlet to the Trent and Mersey Canal and the rest of the country.

The canal therefore attracted the support of some powerful figures such as Philip Gell of Hopton Hall and Sir Richard Arkwright - the latter initially at least. Matters were taken out of the Erewash Canal owners hands, for, without their co-operation, there was the implicit threat that a competing canal would be built to the Trent. The major opposition came from the water-powered mill owners along the Derwent, of which there were many, downstream of the proposed canal, fearful of loss of flow in dry weather. Since, between Cromford and Pinxton, the canal would be level, Jessop was able to give reassurance, carefully downplaying the problem of the descent, with its locks, to Langley Mill.

However, with the assistance of Benjamin Outram, he also spent over a year measuring the flow rate of the Derwent, a precaution which was invaluable when the bill was placed before Parliament. He also proposed to make the summit pound deep enough that it could be replenished on Sundays when the mills were closed, and hold enough water to supply the locks for a week even in the driest weather.

The length from the Erewash Canal would be built to match, accessible to barges from the Trent. Through the Butterley Tunnel and along the narrow Derwent valley it would be to narrow boat standards, similar to the Trent and Mersey.

At the last minute before the Bill was to be presented to Parliament, Richard Arkwright raised a problem. The assumption had been that water would come from Cromford Sough, the drainage from the Wirksworth lead mines. Arkwright complained that the canal crossed his land and insisted that water should be obtained from the river by raising the height of the weir at Masson Mill. This was an unwelcome complication (which would mainly benefit Arkwright himself and his mill) but the canal Committee reluctantly agreed.
