Wast Water, Lake in Wasdale Valley, Lake District National Park, England.
Wast Water is a lake in Wasdale Valley within Lake District National Park, England. It is England's deepest lake and sits surrounded by dramatic mountain slopes that rise steeply from its shores.
During World War II, the lake supplied water to the Royal Ordnance Factory at nearby Drigg. This industrial role supported wartime production in the region.
The name Wast Water combines elements from Old Norse 'vatn' and Old English 'wæter', reflecting the linguistic heritage of the region.
Walking trails circle the lake and connect to routes leading toward surrounding mountain peaks. Most access points and starting places for walks are located in the nearby village of Wasdale.
The southeastern shore is defined by the Wastwater Screes, steep slopes of loose rock that tumble from the mountaintop down to the water level. This unusual formation creates a distinctive landscape rarely found at other lakes in the region.
