Windermere is a ribbon lake in the Lake District in North West England. It is the largest lake in England by length, area, and volume, but considerably smaller than the largest Scottish lochs and Northern Irish loughs. The lake is about 11 miles (18 km) in length and 1 mile (1.6 km) at its widest, has a maximum depth of 64 metres (210 ft), and has an elevation of 39 metres (128 ft) above sea level. Its outflow is the River Leven, which drains into Morecambe Bay. The lake is in the administrative county of Westmorland and Furness and the ceremonial county of Cumbria. It has been one of the country's most popular places for holidays and summer homes since the arrival of the Kendal and Windermere Railway's branch line in 1847.
