Difference between Lake and Pond

Nature has given us some beautiful gifts on earth. The mountains, the lakes, flora, fauna, and the wild species of animals are the beauty of nature. The natural surroundings are soothing and calming for the human mind. Whenever we get a chance to visit somewhere, we choose the mountains and other heavenly gifts of nature. Now, there are a variety of things that nature has to offer. One of these things includes lakes and ponds. Lakes and ponds seem to mean the same. But it is not so. Both are different in two things, i.e., the size and depth. The basic difference is given below.

1. A lake is larger than a pond. A pond is much smaller in size as compared to a lake, river, or ocean.
2. A lake is much deeper than a pond. The sun rays do not reach under the lake. On the other hand, a pond is not deep, and the sun rays can easily fall beneath it.

These are the two basic differences between the two. Lakes and ponds are different from each other.

Now, you must be wondering what a lake is and how it contributes to flora and fauna. Well, without further ado, let us discuss about the lakes in detail.

A lake is considered as an area that is full of water situated on the land. A lake is not part of any river or ocean. A lake is different from lagoons. Now, what is a lagoon? Well, a lagoon is a small water body, unlike a river or an ocean. A lagoon is found in the coastal regions.

Lake vs Pond

There are several natural lakes all over the world. These natural lakes are found in the mountain regions where there are glaciers. Many lakes have been drained from the ice age. All the lakes are temporary except for the ones in the mountain regions. Nowadays, many lakes are temporary and are made for industrial purposes.

It is interesting to know that the word 'lake' comes from the Middle-English word 'lake,' Germanic word 'lako,' and an Old English word 'lacu' meaning a pool or stream. Many limnologists (aquatic life researchers) define lakes as water bodies that are larger than a pond. The size of a lake ranges from 5 acres to 20 acres. Lakes have the following characteristics.

  1. Lake has the same water level on all the parts.
  2. A lake is not part of any ocean or river.
  3. A lake fills several basins.
  4. Lakes are divided based on nutrients and the plants that grow within them (mesotrophic lakes, eutrophic lakes, and hypertrophic lakes).

A majority of lakes are in the northern hemisphere. Canada has around 30,000 lakes, whereas Finland has around 1,80,000 lakes, thereby covering a much larger area than Canada. These all are natural lakes present in particular countries. On the other hand, artificial lakes are used for various purposes like hydroelectric power generation, agricultural use, industrial use, etc. According to some facts, one-third of the water on earth is represented by lakes. There are many kinds of lakes worldwide based on water chemistry, level, volume, and the lakes composed of other liquids. So, let us discuss such kinds of lakes in detail.

  • Ephemeral Lake: It is a seasonal lake that fills and dries up when the season changes.
  • Perennial Lake: It is a lake in which the fluctuations do not occur. This lake remains stagnant in all the seasons.
  • Salt Lake: Salt Lakes are found in arid regions with a high amount of salt in water.
  • Lava Lake: As the name suggests, the lava lake is a lake that consists of molten lava.
  • Hydrocarbon Lakes: The lakes that contain methane and ethane are called hydrocarbon lakes.
  • Eutrophic Lakes: The lakes rich with nutrients that result in good plant growth are called eutrophic lakes.
  • Hypertrophic Lakes: The lakes that are excessively rich in nutrients are called hypertrophic lakes.
  • Mesotrophic Lakes: The lakes that consist of the least nutrients are called mesotrophic lakes.

These are some of the major kinds of lakes present on earth. Some of the notable lakes on earth include:

  • Caspian Sea
  • Lake Michigan-Huron (second largest lake)
  • Lake Baikal (the deepest and the oldest lake in the world)
  • Lake Tanganyika (the longest lake in the world)
  • Manitoulin Island (largest island lake)

These are some of the notable lakes that add to the ecosystem. Lakes are an important part of nature and also give a soothing view to humans. Everything that nature has to offer is essential for the survival of mankind. Along with lakes, ponds also contribute to the ecosystem. Ponds are water bodies that are smaller in size than a lake. A pond can be natural or artificial. Many aquatic plants and animals reside in the ponds. The plants and animals in the pond get affected by various factors like seasons, depth, solar radiations, salinity, etc. One of the major use of a pond is that it is used for agricultural and irrigation purposes. A pond is defined as a body of water that has a surface area of around 10 acres.

A pond cannot be beyond 15 acres. Other uses of ponds include:

  1. A pond is used for the breeding of various organisms.
  2. Ponds are used for irrigation purposes.
  3. Ponds present in villages help the residents in bathing, fishing, washing, etc.
  4. In India, ponds are used for sacred and religious purposes like bathing, immersing the ashes, etc.

One of the key features of a pond is that it provides habitat to various biological organisms. This habitat is referred to as pond life. Ponds include water lilies and aquatic animals like frogs, turtles, snakes, etc.

Ponds provide both environmental and practical benefits to society. Ponds help in reducing the harmful elements from the environment. They also help us in fighting climate change. Some of the notable ponds are:

  • Walden Pond, Massachusetts
  • Christian Pond, Wyoming
  • Hampstead Pond, London
  • Big Pond, Nova Scotia

These are some of the notable ponds. These are only two points of distinction between a lake and a pond which are mentioned above. Lake and pond add to the biodiversity and the beauty of nature. Both lakes and ponds can be natural or artificial. We should learn to preserve the things that nature has offered us. Thus, lakes and ponds contribute to the survival of humans, plants, and animals.
