What are deep vs shallow lakes?
What are deep vs shallow lakes? Deep lakes only mix in spring and fall, and the bottom of deep lakes stays cold and dark because light cannot reach the bottom. Shallow lakes, in contrast, mix all summer because light reaches the bottom of the lake and warms the whole water column. A healthy shallow lake has clear water and dense aquatic plant growth.
At what point does a pond become a lake?
For example, if sunlight can reach the bottom of the entire body of water, it's generally considered a pond, according to the National Park Service. Conversely, if the body of water is deep enough in some places that sunlight cannot penetrate it, it's generally considered a lake.
Which country has the deepest lake in Earth?

What is the difference between a deep lake and a shallow lake?
In sharp contrast to deep lakes, shallow lakes (typically mean depths less than 8 feet) can remain well-mixed and oxygenated from surface to bottom over the summer months. Thus, the depletion of dissolved oxygen is typically not a problem in many shallow lakes.
What is the problem with shallow lakes?
Sunlight warms the entire water column in a shallow lake, therefore the water can mix with the bottom sediments all summer long. Waves caused by wind can also turn to the bottom of shallow lakes and stir up sediments.
