Haweswater is a reservoir in the valley of Mardale, Cumbria in the Lake District, England. Work to raise the height of the original natural lake was started in 1929. It was controversially dammed after the UK Parliament passed a local act of Parliament, the Manchester Corporation Act 1919 (9 & 10 Geo. 5. c. cxix), giving Manchester Corporation permission to build the reservoir to supply drinking water to the city. The decision caused a public outcry because the farming villages of Measand and Mardale Green would be flooded and the valley altered forever.

The reservoir is now owned by United Utilities. It supplies about 25% of the North West's water supply.

## Etymology

[edit]

Haweswater is derived from Old Norse or Old English. 'Hafr's lake' refers to the personal Norse name 'Hafr' or in Old English 'Hæfer'; 'water' or 'wæter' is the dominant term for 'lake' in old English.[2]

## Geology

[edit]

Haweswater is the location of a caldera volcano succession.[3]

## History

[edit]

Parapet atop the Haweswater Reservoir

Haweswater was originally a natural lake about 4 km (2.5 mi) long. A tongue of land at Measand divided the lake almost in two. The upper and lower reaches of the lake were known as High Water and Low Water.

In 1929 work started to build the dam wall across the valley floor. At the time of construction, its design was considered to be at the forefront of civil engineering technology because it was the world's first hollow buttress dam. The wall would be created from 44 separate buttressed units joined by flexible joints. When the dam was completed by 1935, it measured 470 m (1,540 ft) long and 27.5 m (90 ft) high. It has a 1.4 m (4 ft 7 in) wide parapet that runs atop the length of the dam. Building supplies were brought to the site from the adjoining valleys of Heltondale and Swindale. When the valley was flooded, the dam raised the water level by 29 m (95 ft). This created a reservoir 6 km (3.7 mi) long and up to 600 m (2,000 ft) across at its widest point. It holds up to 84 billion litres (18×10 ~~^~~ 9 imp gal) of water.

Before the valley was flooded in 1935, all the farms and dwellings of the villages of Mardale Green and Measand were demolished, as well as the centuries-old Dun Bull Inn at Mardale Green. The village church was dismantled and the stone used in constructing the dam; all the bodies in the churchyard were exhumed and re-buried at Shap.

Today, when the water in the reservoir is low, the remains of the submerged village of Mardale Green can still be seen, including stone walls and the village bridge.[4]

Manchester Corporation built a new road along the eastern side of the lake to replace the flooded highway lower in the valley, and the Haweswater Hotel was constructed midway down the length of the reservoir as a replacement for the Dun Bull. The road continues to the western end of Haweswater, to a car park, a popular starting point for a path to the surrounding fells of Harter Fell, Branstree and High Street.

## Wildlife

### Fish

[edit]

There is a population of schelly fish in the lake, believed to have lived there since the last Ice Age.

### The RSPB at Haweswater

[edit]

The Royal Society for the Protection of Birds (RSPB) first became involved at Haweswater because of the presence of golden eagles – the first to return to England in over 170 years. The organisation currently leases two farms in the area and has rights to their associated common land.

Until 2015, Haweswater was the only place in England where a golden eagle was resident. A pair of eagles first nested in the valley of Riggindale in 1969, and the male and female of the pairing changed several times over the years, during which 16 chicks were produced. The last female bird disappeared in April 2004, leaving the male alone.[5] There was an RSPB viewpoint in the valley for people wishing to see the eagle. The last sighting was in November 2015, and it was reported in 2016 that the 20-year-old bird might have died of natural causes.[6]

Since 2012, the RSPB has leased two farms from the landowner United Utilities.[7][8] The aim is to combine the improvement of wildlife habitats and water quality, with running a viable sheep farm. Moorland and woodland habitats are being improved for birds as well as the rare small mountain ringlet butterfly. Measures include grip blocking, where the water level of drainage ditches is raised to encourage re-vegetation and reduce erosion, heather replanting, and juniper woodland planting (especially in the ghylls).

The RSPB have established the largest native tree and plant nursery in the Lake District.[citation needed] Seed is collected from the existing plants and trees on-site, grown in the nursery and planted to restore the landscape.

## Literary references

[edit]

Hawes Water is described in Anthony Trollope's novel Can You Forgive Her? (1864).[9]

Lake District writer and fell walker Alfred Wainwright had this to say on the construction of the Haweswater Dam in his 1955 book A Pictorial Guide to the Lakeland Fells:

> If we can accept as absolutely necessary the conversion of Haweswater [to a reservoir], then it must be conceded that Manchester have done the job as unobtrusively as possible. Mardale is still a noble valley. But man works with such clumsy hands! Gone for ever are the quiet wooded bays and shingly shores that nature had fashioned so sweetly in the Haweswater of old; how aggressively ugly is the tidemark of the new Haweswater![10]

Haweswater is a 2002 novel by British writer Sarah Hall, set in Mardale at the time of the building of the dam and flooding of the valley.[11] It won the 2003 Commonwealth Writers' Prize for a First book.[12] The novel was released in the United States as a paperback original in October 2006, by Harper Perennial.

The RSPB's site manager at Haweswater, Lee Schofield, published Wild Fell: Fighting for Nature on a Lake District Hill Farm (2022), a personal account of the charity's work at the site.
