  • Have you ever swum in a lake?
  • What about a pond?
  • Is there a difference between the two?


Lakes and ponds are aquatic biomes.

A biome is a large part of the earth that has specific types of animals and plants living there. For example, the desert is a biome. Lakes and ponds are biomes, too, even though they are so different from deserts!

  • Do you know the difference between a lake and a pond?

A lake is a large body of water. Most lakes are freshwater, but some, like the Great Salt Lake in Utah, are made up of salt water. Saltwater lakes are generally found near the ocean.

Lakes get their water from glaciers, rivers, and streams. Lakes are surrounded by higher land, like hills and mountains. This helps lakes keep their water, rather than all pouring out of the lake.

A pond is much smaller than a lake. Ponds often get their water from underground springs. Hills and mountains usually surround the water in a pond. This keeps the water from draining out of the pond.

The picture on top shows a lake, the picture on the bottom shows a pond.

Lakes and ponds are divided into four zones.

The first zone, found at the top of lakes and ponds, is called the littoral zone. The littoral zone is the warmest part of the water.

  • Why is it the warmest part of a lake or pond?

Great work! The littoral zone is the warmest because it is the closest to the sun! Here you will find various types of aquatic plants, like algae and lily pads. You will also find snails, crustaceans, fish, and amphibians living in this zone.

Below the littoral zone is the limnetic zone, or photic zone. The limnetic zone is cooler than the coastal zone, although this zone still receives light from the sun. Fish and plankton can be found living in this zone.

Beneath the limnetic zone is the profundal zone, or aphotic zone. This zone doesn't get much light. Some fish and amphibians can be found living in this zone.

At the very bottom is the benthic zone. The benthic zone gets no light from the sun. The benthic zone is found at the bottom of a body of water. This includes the soil and sediment found at the bottom of the lake or pond.

Check out the picture below to see the different zones. Don't forget the benthic zone is at the very bottom of the water. It is not pictured below.

Lakes and ponds change with the temperature.

Depending on where a lake or pond is located, the temperature of the water will change. For example, a lake that is found near the equator and gets more sunlight will be much hotter than a lake found in the northern parts of Canada.

As the environment changes, so do lakes and ponds. They expand and shrink depending on the temperature and rainfall.

  • Have you ever seen a pond after days and days of rain?

Some ponds and lakes may overflow and flood the surrounding land after heavy rainfall.

Lakes and ponds are not permanent. Some lakes and ponds dry up.

  • Can you imagine a lake or pond that has dried up?

The picture below shows Owens Lake, found in California. This lake dried up because Owens River was diverted to send water to Los Angeles, removing all the water Owens Lake needed to stay full.
