Offering fresh water is the best benefit of the lakes that we get. Not only in our lives, but there is also the importance of lakes in the environment.

Importance of Lakes | Definition | Types | Pollution Effects

Lakes are mainly formed due to the melting of glaciers. There are many types of lakes in the world where we will get individual importances of lakes. But pollution effects on the lakes badly. And as a result, the importance of lakes is getting reduced day-by-day.

What is Lake

When a surrounded part of land contains certain water and localized in a basin, we call it a lake. Rivers and streams fed and drain most of the lakes. You can see the natural lakes in mountainous areas, rift zones, and areas with ongoing glaciation. Lake Erie and Lake Ontario are the instances of lakes.

Types of Lake

Here, we are providing the names or different types of lakes from where you get to know also the importance of lakes.

  • Organic lakes

These are small size lakes and also rare seen. Organic lakes form with the help of action of flora or fauna. A reservoir is an instance of an organic lake which is made by the damming of a river by the action of beavers.

  • Volcanic lakes

If any lake is the origin of the volcano, then we call these as volcanic lakes. We get to see the volcanic lakes in volcanic craters or calderas. It occurs while the precipitation rate is higher than the rate of water loss via evaporation or drainage through an outlet. Creator Lake that is within Mount Mazama’s caldera in Oregon, USA is an example of a volcanic lake.

  • Glacial lakes

A melted glacier can form this type of lakes. The Great Lakes is an instance of glacial lakes. Besides, the Lake District of England is also an example of glacial lakes.

  • Tectonic lakes

These types of lakes are formed with the help of the deepest and largest lakes in the world. The Caspian Sea and the Sea of Aral are a few of the instances of tectonic lakes.

  • Fluvial lakes

Sometimes, a river doesn’t flow straight, it has to bend throughout its course due to the uneven and non-uniform topography of the land. At that time, many lakes are formed. Crater Lake is an example of it.

  • Landslide lakes

It is formed due to the dam of a river by the deposition of debris resulting from a rock avalanche, landslide, mudflow, etc.

  • Solution lakes

While the bedrock is soluble, these types of lakes are formed.

  • Aeolian lakes

The reason for its formation is the action of winds. Moses Lake that is in Washington is an example of it. These lakes are seen in arid environments. We call these as interdunal lakes also.

  • Shoreline lakes

These lakes are formed due to the deposition of sediments by rivers, wave action, or ocean currents.

  • Anthropogenic lakes

The reason for the anthropogenic lakes is human activities. People use these lakes for different purposes such as the generation of hydroelectricity, storage of water for future needs, pisciculture, etc.

  • Meteorite lake

The reason for its formation is a meteor or asteroid crashing on to the Earth’s surface.

Pollution Effects on Lakes

  • When the number of nutrients increases in the lakes, it results in toxin build-up, the oxygen level drops, fish kills, and other poor conditions for recreation.
  • Metals are also one of the reasons which pollute lakes. Mercury and lead are those metals which cause pollution in lakes.
  • Particles such as silt and clay effect in the environment when these mix into the lakes in a large amount.

Importance of Lakes:

The importance of lakes are as follows:-

  1. Lakes help to prevent the risk of droughts and floods by storing large amounts of water and releasing it during shortages.
  2. It helps to replenish groundwater and improves the quality of downstream watercourses, and preserve the biodiversity and habitat of the area.
  3. Using lakes as water supplies for industry and an irrigation source for agriculture is a great importance of lakes.
  4. We can get help from lakes such as recreation, tourism, and cottage or residential living.
  5. The importance of lakes comes mainly when we say about freshwater. Besides, these contain their historical and traditional values.

Why are Lakes Importance for Human and Environment

Importance for Human Importance for Environment
Lake delivers freshwater to us fir different usages. Lakes prevent floods and droughts.
Humans depend on fishes as these are part of their lives. Lakes play here an effective role. These are the source of freshwater that is the main importance of lakes.
Lake is a nutrient-rich water body. Lakes provide water in the agriculture area.
It acts as a waterway. Lakes replenish groundwater.
Humans use lakes also for tourism purposes in different hill stations. It preserves the biodiversity of the environment.

Why We Should Save Lakes

Everyone should know properly what is the importance of lakes in human life as these are the only source of fresh water. The lakes play a crucial role in replenishing groundwater.
