Restoring the Stroudwater Navigation and Thames & Severn Canal


Trow Image The History of the Cotswold Canals

There were many early attempts to build a navigation from the River Severn to Stroud. In the 1740s Richard Owen Cambridge built a man made waterway near to Wheatenhurst for pleasure purposes. The Kemmett Canal was built between 1759 and 1763 from Framilode to the Stonehouse area. It was the earliest known example of container traffic on an inland waterway.

The Stroudwater Canal was built between 1775 and 1779 from Framilode, on the banks of the River Severn, to Wallbridge, Stroud. From the beginning, the canal was very profitable, and with the success of the canal the Stroudwater Canal Company was soon looking to extend it towards London. In 1781 they commissioned a survey of the line from Stroud to Cricklade on the River Thames which recommended the Stroud to Cirencester route. However, the surveyor, Robert Whitworth, warned that trouble would be encountered on the summit, which was to be built over "bad rocky ground".

A Bill was introduced in 1783 and construction of the canal was expected to take six years. Josiah Clowes was appointed Resident. On 31st January 1785 the first vessel passed through the lock at Wallbridge in Stroud and went up the new canal as far as Chalford. The 241 feet rise from Wallbridge to the summit level at Daneway (near Sapperton) was completed in the summer of 1786 requiring 28 locks over a distance of seven miles.

At the summit came Sapperton Tunnel, the largest and longest canal tunnel built up to that time. Even to this day, its length has only been exceeded by two other canal tunnels in this country. It is 3817 yards long and about 14 feet wide by 15 feet high. Work on the tunnel started in 1784 and, after problems with the difficult ground and an incompetent contractor, was completed in 1789. The first boat passed through the tunnel on the 7 mile summit pound to Cirencester in April 1789.

Work had proceeded meanwhile to the eastern side of the summit where the canal descends 129 feet over 13 miles via 15 locks to the Thames. The first boat reached the River Thames at Inglesham Lock on 20th November 1789. A construction time of six and a half years.

Lack of experience in the design and construction of canals anywhere resulted in a shortage of water almost from the first day. Numerous locks were built to varying lifts and due to the narrowness of the Golden Valley were constructed with intervening pounds of insufficient capacity. These problems, coupled with fissured limestone ground on the summit, made it wasteful of water. After using a wind pump for some years, the Company installed a Boulton & Watt single acting beam engine at Thames Head. In 1854 the Watt engine was replaced with a cornish beam engine of much higher capacity. The new engine could deliver three million gallons of water to the summit pound every 24 hours. The engine was scrapped in 1941 to aid the war effort.

The years 1820 to 1845 brought many improvements to the locks and constant maintenance kept leaks to a minimum. All of the locks between Chalford and South Cerney were shortened creating the characteristic double top gate recesses and side ponds were added to some of the locks in the Golden Valley. The efficiency of the navigation was marked by steadily increasing receipts which peaked in 1841. However, competition from the railways was growing and at the end of 1893, a notice was issued closing the canal east of Chalford until further notice. Despite many protests the canal remained closed, but eventually led to the formation of a trust which took over the canal. The Trust was formed by six other canal companies and five local authorities who reopened the canal throughout its length in March 1899. This achievement was short-lived however, as leakage on the summit caused the canal to close once again in June of that year.

In 1901 the canal was transferred to Gloucestershire County Council who began further restoration work. The length of canal from Cirencester to the River Thames was reopened in July 1902, from Stroud to Daneway in April 1903, and the summit pound in January 1904. The first vessel over the reopened summit was the "Staunch" in March 1904. The restored canal was still not completely reliable and was closed for at least twelve weeks of each year in 1905, 1906, and 1908 for repairs to the summit. It was also closed for twelve weeks in 1907 for repairs to Puck Mill Pound, which was emptying in four hours through leaks in the clay puddle lining.

The last loaded boat passed over the summit in May 1911 and only a few repairs were carried out in the next four years. In 1927 the canal was formally abandoned from Lechlade to Whitehall Bridge in the Golden Valley, and in 1933 the remaining length to Stroud was also abandoned. The Stroudwater Canal, which had remained independent, carried on until 1941 when traffic of all kinds effectively ceased. It was abandoned by Act of Parliament in 1954 despite vigorous lobbying to keep it open by local figures, notably Mrs Airey .

The fifteen years following the abandonment of the Stroudwater Canal were the most destructive period in its history. The sections of the Thames & Severn Canal abandoned in the early part of the century very soon became derelict. Sapperton Tunnel suffered two roof collapses and sections of the canal were returned to agricultural use or had factory buildings erected over them. The construction of the M5 motorway and its link road to the A38 resulted in the loss of Bristol Road and Meadow Mill Locks and the one mile of canal linking them. A flood relief scheme by SevernTrent Water Authority in the vicinity of Whitminster, merged the canal with the River Frome for about 400 yards and resulted in the infilling of Whitminster Lock.

A total of nine swing bridges were fixed, including Walk. Over the years the remaining locks were allowed to decay with various service pipelines being installed at water level. British Rail enclosed the bridge over the canal at Stonehouse Court with an "armco" tube and the road crossings at Stonehouse and Bath Road, Stroud were infilled. More recently the canal at Capels Mill Viaduct was infilled to provide the Stroud East/West Bypass. However, a bridge was incorporated into the scheme to allow future restoration.

In 1996 Gloucestershire County Council commissioned British Waterways to make a corridor study. The resulting report examined the cost benefit of full or partial restoration and concluded that in either case the benefits to the local community were extremely good both in terms of payback and number of jobs created.

Ownership of most of the Stroudwater Canal still remains with the original company with whom the Cotswold Canals Trust enjoys close cooperation. After abandonment Gloucestershire County Council sold much of the Thames & Severn east of Chalford to the riparian landowners. The Trust leases a section of canal on the outskirts of Stroud from the County Council and itself owns a section near Frampton Mansell, at Puck Mill.

The Canal Trust has promoted a reversal of the destructive processes and has undertaken specific restoration works using volunteer . Volunteers come from both trust members, the Waterways Recovery Group and Dig Deep. The result of all this effort has been that most of the canal corridor has been declared a Conservation Area.
