The River Etherow is a river in northern England, and a tributary of the River Goyt. Although now passing through South Yorkshire, Derbyshire and Greater Manchester, it historically formed the ancient county boundary between Cheshire and Derbyshire. The upper valley is known as Longdendale. The river has a watershed of approximately 30 square miles (78 km2), and the area an annual rainfall of 52.5 inches (1,330 mm).
Rising in the Redhole Spring and Wike Head area of Pikenaze Moor in Derbyshire, the river broadens into the Longdendale Chain of reservoirs in the Peak District National Park. It emerges again in Tintwistle, Derbyshire, at the foot of Bottoms Reservoir dam [1] and passes Melandra Castle in Gamesley, where it is joined by Glossop Brook. [2] The Etherow enters the borough of Tameside at Hollingworth in Greater Manchester, passing into Stockport where it passes through Etherow Country Park. It flows into the River Goyt at Brabyns Park near Marple.
The modern accepted start of the River Mersey is at the confluence of the Tame and Goyt, in central Stockport, 4 miles (6 km) downstream. [3] However, older definitions, and many older maps, place its start at the confluence of the Etherow and Goyt; for example the 1911 Encyclopædia Britannica states "It is formed by the junction of the Goyt and the Etherow a short distance below Marple in Cheshire on the first-named stream." John Stockdale's map published on 12 April 1794 shows the Mersey River extending to at least Mottram, and forming the boundary between Cheshire and Derbyshire. [4]
The upper reaches of the River Etherow pass through peat moorland, inhabited by red foxes, voles and an introduced population of mountain hare. Red grouse, ring ouzel, wheatear and golden plover may be seen. Kestrels, merlins and short-eared owls nest here. The reservoirs attract mallards, and also teal, pochard, common sandpipers, black-headed gulls and Canada geese. The woodlands are home to redstart, great spotted woodpecker, and spotted flycatcher. [5] Water rail have been recorded at Etherow Country Park. [6]
Longdendale is a steep-sided V-shaped valley that is glacial in origin. Longdendale is in the Dark Peak, where a thick blanket of peat overlies the Millstone Grit sandstone, formed on a bed of shale through which flows the Etherow. Directly beneath the upper valley lie areas of Carboniferous Millstone Grit, shales and sandstone. It is on the edge of the Peak District Dome, at the southern edge of the Pennine anticline. The Variscan uplift has caused much faulting and Glossopdale was the product of glacial action in the last glaciation period that exploited the weakened rocks. The steep-sided valleys of the cloughs cause significant erosion and deposition. The layers of sandstone, mudstones and shale in the bedrock act as an aquifer to feed the springs. The valley bottoms have a thin deposit of boulder clay. The brooks are fed by the peaty soils of the moors and are, therefore, acidic (pH5.5–7.0). [7]
The Etherow valley was an important trans-Pennine route, and in AD 78 the Romans under Agricola built the fort of Ardotalia (later known as Melandra or Melandra Castle) to defend it. The Mercians settled at Hollingworth about 650 AD. Many placenames of the area date from this period; for example, Mottram and Glossop. At the time of Domesday (1086) the river was firmly established as the boundary between Cheshire and Derbyshire, but the name Edrow or Etherow applied to this upper reach of the Mersey cannot be dated earlier than c.1772. [8]
A packhorse route (known as a saltway) was maintained from the Middle Ages onwards to allow the export of salt from the Cheshire towns of Nantwich, Northwich and Middlewich across the Pennines. The saltway followed the Etherow to Ladyshaw, and at Salters Brook ( SK137999 ) it forked, with one route leading to Wakefield and another to Barnsley. [9]
Water was an important source of power for industry, and the Etherow and its tributaries were fast flowing and constant. Watermills were used to grind meal and to full woollen cloth (Littlemoor 1781). Wool was transported along the turnpike road (1731) that ran from Ashton-under-Lyne, Stalybridge, Mottram, Woodhead and Lady's Cross to Sheffield, to be woven on hand-looms in the dale. [10]
From 1782 to 1820, water-powered cotton mills were built along many brooks feeding the Etherow, including six on the Glossop side of the river. With the adoption of steam to power the ever-larger mills, built closer to the coal fields, the river assumed a new role as a source of water for Manchester and Salford. In 1844 John Frederick Bateman advised Manchester Corporation that the River Etherow, which rose at the highest point of the Pennine chain, could provide water, collected in purpose-built reservoirs, "nearly as pure as if it comes from the heavens." This led to the construction of the Longdendale Chain of reservoirs, the first scheme of its type in the world. Three reservoirs were built on the Etherow to impound drinking water, with another two to provide compensation water for the mills downstream. [11]
The name Etherow could be of Brittonic Celtic origin and derived from the ancient term *ador, meaning "watercourse, channel". [12] The settlement-name Tintwistle, however, implies that Etherow may be an Old English replacement for an earlier name of the *Tin- type (see River Tyne), derived from the hydronym *edre, which is possibly related to ēdre, "vein". [12]
The Longdendale Chain of reservoirs comprises three impounding reservoirs, Woodhead Reservoir, Torside Reservoir and Rhodeswood Reservoir, supplying 24,000,000 imperial gallons (110 Ml) of water a day by gravity to Manchester and Salford, and 6,600,000 imperial gallons (30 Ml) to Hyde and Denton through the Mottram tunnel. Valehouse Reservoir and Bottoms Reservoir are compensating reservoirs which have a combined holding capacity of 4,200,000,000 imperial gallons (19,000 Ml).
The Woodhead Line, which followed the river from Hadfield to the Woodhead Tunnel portal, was an important cross-Pennine route built in 1844 by the Sheffield, Ashton-under-Lyne and Manchester Railway. Three tunnels of 4,840 metres (15,880 ft) were dug, connecting Woodhead with Dunford Bridge on the River Don. Though now closed to railway traffic, one tunnel is used to route electricity cables for the National Grid, with work in progress to use a second tunnel for a new cable, thus preventing the re-establishment of rail traffic.
Following the closure of the railway line, the trackbed was taken up and the Longdendale Trail constructed along its route. This is now part of the Trans-Pennine Trail, Sustrans National Cycle Route 62. [13] This, in its turn, is part of the 2,000 miles (3,200 km) European walking route E8 from Liverpool to Istanbul. The Pennine Way crosses Longdendale, descending from Bleaklow to the south and ascending Black Hill to the north. The youth hostel at Crowden is a traditional stop after the first day's walking, from Edale.
The circular walk known as 'The Longdendale Edges' takes in the high ground (at about the 1,000 feet (300 m)-1,500 feet (460 m) level) on both sides of the valley. It is about 17 miles (27 km) long and is 'not recommended in doubtful weather'.[ citation needed ] The detailed route, clockwise from Crowden Youth Hostel, is given in Peak District Walking Guide No.2, published by the Peak Park Planning Board.[ citation needed ]
Torside Reservoir is home to Glossop & District Sailing Club and Etherow Country Park is the home to Etherow Country Park Sailing Club. [14] [15]
Etherow Country Park, in Compstall, close to the mouth of the Etherow, opened in 1968 as one of the UK's first country parks.[ citation needed ] Originally it was an industrial area incorporating a mine, a mill and a mill pond. The River Etherow flows through the park and is the source for the mill pond. Etherow Country Park is associated with many local groups, including a small local community group, the Friends of Etherow, anglers, the afore-mentioned sailing club, and a model boat club.
Compstall Nature Reserve is a 12.8-hectare (32-acre) region of the park which is designated a Site of Special Scientific Interest (SSSI). The area was given the designation in 1977 for its biological interest, in particular its wide range of habitats, including open water, tall fen, reed swamp, carr and mixed deciduous woodland. [6]

The Etherow has no major tributaries; it is fed by numerous brooks and streams from the cloughs flowing off Kinder Scout, Bleaklow and Black Hill. Minor left tributaries are:
Minor right tributaries are:
Glossop is a market town in the Borough of High Peak, Derbyshire, England. It is located 15 miles (24 km) east of Manchester, 24 miles (39 km) north-west of Sheffield and 32 miles (51 km) north of the county town, Matlock. Glossop lies near Derbyshire's borders with Cheshire, Greater Manchester, South Yorkshire and West Yorkshire. It is between 150 and 300 metres above sea level and is bounded by the Peak District National Park to the south, east and north.
Longdendale is a valley in the Peak District of England, north of Glossop and southwest of Holmfirth. The name means "long wooded valley" and the valley is mostly in the counties of Derbyshire and Greater Manchester.
Broadbottom is a village in Tameside, Greater Manchester, England. Historically in Cheshire, it stands on the River Etherow which forms the border with Derbyshire.
Mottram in Longdendale is a village in Tameside, Greater Manchester, England. At the 2011 census, the population for the ward of Longdendale, which includes Mottram and the surrounding area, was 9,950.
The River Goyt is a tributary of the River Mersey in North West England.
The M67 is a 5-mile (8.0 km) urban motorway in Greater Manchester, England, which heads east from the M60 motorway passing through Denton and Hyde before ending near Mottram. The road was originally conceived as the first section of a trans-Pennine motorway between Manchester and Sheffield that would connect the A57(M) motorway with the M1 motorway; however, the motorway became the only part to be built.
The River Tame flows through Greater Manchester, England. It rises on Denshaw Moor and flows to Stockport where it joins the River Goyt to form the River Mersey.
Hadfield is a town in the High Peak of Derbyshire, England, with a population at the 2021 Census of 6,763. It lies on the south side of the River Etherow, near to the border with Greater Manchester, at the western edge of the Peak District close to Glossop.
Woodhead is a small and scattered settlement at the head of the Longdendale valley in Derbyshire, England. It lies on the trans-Pennine A628 road connecting Greater Manchester and South Yorkshire, 6 miles (10 km) north of Glossop, 19 miles (31 km) east of Manchester and 18 miles (29 km) west of Barnsley. It is close to the River Etherow and the Trans Pennine Trail. Although part of Derbyshire since 1974, like nearby Tintwistle and Crowden, the hamlet was in the historic county of Cheshire.
Crowden is a hamlet in the High Peak borough of Derbyshire, England. Historically a part of Cheshire, Crowden was incorporated into Derbyshire for administrative and ceremonial purposes in 1974 and is now Derbyshire's most northerly settlement. It lies in the Longdendale valley, 5.8 miles (9.3 km) north-east of Glossop and 5.7 miles (9.2 km) south-west of Holme in West Yorkshire.
Woodhead reservoir is a man-made lake near the hamlet of Woodhead in Longdendale in north Derbyshire, England. It was constructed by John Frederick Bateman between 1847 and June 1877 as part of the Longdendale Chain of reservoirs to supply water from the River Etherow to the urban areas of Greater Manchester. It is at the top of the chain of reservoirs and was the first to be started, though, due to construction problems, it was the last to be completed.
Torside Reservoir is the largest man-made lake in Longdendale in north Derbyshire, England. It was constructed by John Frederick Bateman between April 1849 and July 1864 as part of the Longdendale Chain of reservoirs to supply water from the River Etherow to the urban areas of Greater Manchester.
Rhodeswood Reservoir is a man-made lake in Longdendale in north Derbyshire, England. It was constructed by John Frederick Bateman between 1849 and June 1855 as part of the Longdendale Chain of reservoirs to supply water from the River Etherow to the urban areas of Greater Manchester. It is third in the chain, and it is from here that the water is extracted to pass through the Mottram Tunnel to Godley for Manchester.
ValehouseReservoir is a man-made lake in Longdendale in north Derbyshire, England. It was built between 1865 and 1869 as part of the Longdendale Chain of reservoirs, which was built to supply water from the River Etherow to the urban areas of Greater Manchester, while maintaining a constant flow into the river. The upper reservoirs supply the drinking water, while Vale House and Bottoms are compensation reservoirs which guarantee the flow of water to water-powered mills downstream. Valehouse, with a crest elevation of 503 metres (1,650 ft), is too low to supply water under gravity to the Mottram Tunnel, so could not be used as an impounding reservoir. Today 45 megalitres of compensation water are released each day into the River Etherow.
Arnfield Reservoir is a man-made lake in Longdendale in north Derbyshire, England. It was constructed in 1854 as part of the Longdendale chain to supply water from the River Etherow to the urban areas of Greater Manchester. Unlike the other reservoirs in the chain, Arnfield and Hollingworth Reservoir are not in the Etherow valley but lie in the valley of tributary brooks to the north and above. From Arnfield the water is extracted to pass through the Mottram Tunnel to Godley.
The Longdendale Chain is a sequence of six reservoirs on the River Etherow in the Longdendale Valley, in northern Derbyshire. They were constructed between 1848 and 1884 to a design by John Frederick Bateman to supply the growing population of Manchester and Salford with fresh water.
The A628 is a major road connecting Greater Manchester and South Yorkshire in northern England. It crosses the Pennine hills by way of Longdendale and the Woodhead Pass in the Peak District National Park. The road's altitude and exposure to bad weather create problems in winter and the road is sometimes closed due to snow or high winds.

The Mottram Tunnel is a tunnel carrying drinking water by gravity from Arnfield Reservoir, Tintwistle, Derbyshire, in the valley of the River Etherow, to Godley, Greater Manchester, in the valley of the River Tame. It was essential to the construction of the Longdendale Chain of reservoirs constructed by John Frederick Bateman. The tunnel was built between August 1848 and October 1850, and the Godley Reservoir was finished in 1851 to receive and filter the water.
