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.

Shallow lakes are lakes where the sunlight can reach the bottom. Generally, this corresponds to 10-15 feet deep or less. Since the sunlight can reach the bottom, plants are able to grow there. There are over 5,000 shallow lakes in Minnesota that are over 50 acres in size.
Lake Baikal, in Siberia, holds the distinction of being both the deepest lake in the world and the largest freshwater lake, holding more than 20% of the unfrozen fresh water on the surface of Earth. It is also the oldest freshwater lake in the world, with an estimated age of 20 million to 25 million years.
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.
The Smallest Lake in the World – Lake AisoIn contrast, Lake Aiso is considered to be the smallest lake in the world. Located in Bevagna, Italy, Lake Aiso has a diameter of just 25 meters and goes 13 meters deep.
Not only is Lake Baikal safe to swim in, but it also boasts some of the purest water in the world. The only drawback is the temperature - even during the warmer months, a dip in the lake is pretty invigorating.
Lake Baikal is so deep because it is located in an active continental rift zone. The rift zone is widening at a rate of about 1 inch (2.5 centimeters) per year. As the rift grows wider, it also grows deeper through subsidence. So, Lake Baikal could grow wider and deeper in the future.
