# List of lakes of the Lake District

This list contains the lakes, tarns and reservoirs in the Lake District National Park in Cumbria, England.
Only one body of water, Bassenthwaite Lake, is traditionally named a lake. Larger bodies of water in the Lake District are generally named as mere or water, whilst smaller ones are denoted by tarn. Some writers, particularly in the media, refer to Lake Windermere though this use is deprecated.

## Physical characteristics of the main lakes

## Map of major lakes

The map shows the locations of the lakes with a volume over 4 x 10$^6$ m³ and gives an indication of the volume of water in each lake. The markers suggest this by showing the size of a drop of water where the volume of the drop would be in proportion to the quantity of water in the lake (the diameter of the drop is proportional to the cube root of the lake's volume).
