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).
Coniston Water is a lake in the Lake District in North West England. It is the third largest by volume, after Windermere and Ullswater , and the fifth-largest by area. [ 1 ] The lake has a length of 8.7 kilometres ( 5 + 3 ⁄ 8 mi), a maximum width of 730 metres (800 yd), and a maximum depth of 56.1 m (184 ft 1 in).
The Lake District is a major sanctuary for the red squirrel and has the largest population in England (out of the estimated 140,000 red squirrels in the United Kingdom, compared with about 2.5 million grey squirrels). [41] The Lake District is home to a range of bird species, [42] and the RSPB maintain a reserve in Haweswater. [43]
Graph of Dissolved Oxygen and Water Temperature for Little Muskego Year 1999. The average pH for Little Muskego in 1999 was 7.8 [6] The minimum water temperature is 0.5 degrees Celsius (32.9 F) with a maximum of 26.67 degrees Celsius (80.01 F). [3] The average Secchi depth is 1.65 meters (5.4 feet). [3] It is classified as a dimictic lake.
Lake stratification is the tendency of lakes to form separate and distinct thermal layers during warm weather. Typically stratified lakes show three distinct layers: the epilimnion, comprising the top warm layer; the thermocline (or metalimnion), the middle layer, whose depth may change throughout the day; and the colder hypolimnion, extending to the floor of the lake.
As the temperature continues to drop, the water on the surface may get cold enough to freeze and the lake/ocean begins to ice over. A new thermocline develops where the densest water (4 °C (39 °F)) sinks to the bottom, and the less dense water (water that is approaching the freezing point) rises to the top.
Temperature regimes are very different in large lakes. In temperate regions, for example, as air temperatures increase, the icy layer formed on the surface of the lake breaks up, leaving the water at approximately 4 °C. This is the temperature at which water has the highest density.
Ullswater is a glacial lake in Cumbria, England and part of the Lake District National Park. It is the second largest lake in the region by both area and volume, after Windermere . The lake is about 7 miles (11 km) long, 0.75 miles (1 km) wide, and has a maximum depth of 63 metres (207 ft).
