Description
Chew Valley Lake is a reservoir in Chew Stoke, Chew Valley, Somerset, England. It is the sixth-largest artificial lake by area in the United Kingdom, with an area of 1,200 acres (4.9 km2), but only the forty-seventh largest by volume, reflecting the fact it is a shallow lake. The lake, created in the early 1950s, was opened by Queen Elizabeth II in 1956. It provides much of the drinking water for the city of Bristol and surrounding area, taking its supply from the Mendip Hills. Some of the lake water is used to maintain the flow in the River Chew.
