The technical distinction between a pond and a lake has not been universally standardized. Limnologists and freshwater biologists have proposed formal definitions for pond, in part to include 'bodies of water where light penetrates to the bottom of the waterbody', 'bodies of water shallow enough for rooted water plants to grow throughout', and 'bodies of water which lack wave action on the ...
an oxbow lake; a pond or still body of water created when a river changes course and some water becomes trapped. Located in Australia Boil: see seep: Bog: a type of wetland that accumulates peat due to incomplete decomposition of plant matter. Bourne or Winterbourne: a brook; stream; small, seasonal stream.

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.
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.
Ephemeral lake is a short-lived lake or pond. [49] If it fills with water and dries up (disappears) seasonally it is known as an intermittent lake [50] They often fill poljes. [51] Dry lake is a popular name for an ephemeral lake that contains water only intermediately at irregular and infrequent intervals. [36] [52]
Last summer, Lake Michigan was 10 degrees above normal, which resulted in the water taking longer to cool down in the winter. At the start of the year, only 3% of the Great Lakes were covered in ice.
It enters the water mostly via diffusion at the water-air interface. Oxygen's solubility in water decreases as water temperature increases. Fast, turbulent streams expose more of the water's surface area to the air and tend to have low temperatures and thus more oxygen than slow, backwaters.
Some ponds and lakes such as Park Lake in Rockaway completely prohibit ice skating due to insurance regulations that include daily drilling in multiple spots and the temperature maintenance of 20 ...
