Wast Water or Wastwater (/ /) is a lake located in Wasdale, a valley in the western part of the Lake District National Park, England. The lake is almost 3 miles (4.8 km) long and more than one-third mile (500 m) wide. It is a glacial lake, formed in a glacially 'over-deepened' valley. It is the deepest lake in England at 258 feet (79 m). The surface of the lake is about 200 feet (60 m) above sea level, while its bottom is over 50 feet (15 m) below sea level. It is owned by the National Trust.
The head of the Wasdale Valley is surrounded by some of the highest mountains in England, including Scafell Pike, Great Gable and Lingmell. The steep slopes on the southeastern side of the lake, leading up to the summits of Whin Rigg and Illgill Head, are known as the "Wastwater Screes" or on some maps as "The Screes". These screes formed as a result of ice and weathering erosion on the rocks of the Borrowdale Volcanic Group, that form the fells to the east of the lake, towards Eskdale. They are approximately 2,000 feet (600 m), from top to base, the base being about 200 feet (60 m) below the surface of the lake.
A path runs the length of the lake, through the boulders and scree fall at the base of the craggy fell-side. On the northwestern side are the cliffs of Buckbarrow (a part of Seatallan) and the upturned-boat shape of Yewbarrow. Wast Water is the source of the River Irt which flows into the Irish Sea near Ravenglass.
Name origin and pronunciation
"Wastwater" comes from "Wasdale" plus English "water". " 'Wasdale lake' or 'the lake of Vatnsá, lake river'. The present name rather curiously contains the reflexes of both Old Norse 'vatn' 'water', 'lake', and Old English 'wæter' 'water', with the meaning 'lake' probably influenced by the Old Norse 'vatn'.
The valley is pronounced as in was, not with a hard a: the name of the lake similarly but with a soft "s" as in "thou wast". The lake is named "Wast Water" on Ordnance Survey maps but the spelling "Wastwater" is used with roughly equal frequency, including by its owner, the National Trust, along with the Cumbria Tourist Board, and the Lake District National Park Authority.
Points of interest
The Lady in the Lake
In 1976, The Wasdale Lady in the Lake, Margaret Hogg, was murdered by her husband and her body was disposed of in the lake. She was found after eight years, with her body preserved like wax due to the lack of oxygen in the water.
In February 2005 it was reported that a "gnome garden" complete with picket fence had been placed in the lake as a point of interest for divers to explore. It was removed from the bottom of Wastwater after three divers died in the late 1990s. It is thought the divers spent too much time too deep searching for the ornaments. Police divers report a rumour that the garden had been replaced at a depth beyond the lowest they were allowed to dive.
PC Kenny McMahon, a member of the North West Police Underwater Search Unit, said
Wastwater is quite clear at the bottom, but there's nothing to see. At a depth of about 48 m [157 ft], divers had taken gnomes down and put a picket fence around them. But several years ago there were a number of fatalities and the Lake District National Park Authority asked us to get rid of them. We went down there, put them in bags and removed the lot. But now there's a rumour about a new garden beyond the 50 m [160 ft] depth limit. As police divers we can't legally dive any deeper so, if it exists, the new garden could have been purposefully put out of our reach.
Water was first pumped from the lake during World War II to supply the Royal Ordnance Factory at Drigg. It is pumped to the nearby Sellafield nuclear facility as an industrial water supply. The Nuclear Decommissioning Authority is allowed to extract from the lake a maximum of 4,000,000 imperial gallons (18,000 m3) a day to use on that site.
On 9 September 2007, Wast Water was announced as the winner of a vote to determine "Britain's Favourite View" by viewers of ITV.
