1. Difference between pond
lake and river
Dr. Asha Jyoti Bharati

2. Our planet is covered by more than 70%
water which is around 3/4 of the area.
Water is very important in everyday
life. The nature of this water can be
either fresh or salt.
There are different types of water
bodies.
These waterbodies are the habitat of the
smallest aquatic organisms to largest
aquatic organisms.
Water bodies are in the form of sea,
waterfall, river, pond, and lake.

3. Pond, lake, and river, their
characteristic, properties and major
difference

4. Characteristics and
Importance of pond

5. The pond is a kind of stable freshwater body.
It is smaller in size than the lake.
Ponds are natural or artificial.
Unlike rivers or streams, the water in the pond is
stagnant.
The depth of a pond is about 1.8 meters. Hence, sunlight
can enter the bottom of most ponds.
Naturally-made ponds are of any size, but man-made
ponds are almost quadrangular in shape.
Pond water is relatively hotter than river water.
The amount of oxygen in the bottom is low and is
covered with silt
Characteristics of pond

6. Importance of pond
Ponds are a habitat for many aquatic
organisms.
Ponds work as mini reservoirs during the
rainy season.
It recycles nutrients and reduces the
amount of nitrate and phosphate.
Ponds are nowadays getting extinct due to
human activity.
Therefore, the conservation of ponds is
very important for maintaining the
ecosystem of different species in the ponds
and maintaining the balance of nature.

7. Characteristics and
Importance of river

8. Rivers are continuous flowing freshwater
bodies created by nature.
A river flows from top to bottom according
to the land slope.
The stream of the river flows over the
surface.
Water in the river is nourished by ice or
rainwater.
The river falls into any lake or sea.
A river has many distributaries (a stream of
water flowing from the main river) and many
tributaries (mixed streams in the main river).
Characteristics of the river

9. Importance of river
In the past, various river-centric civilizations
(Egyptian civilization centered on the Nile) were
formed.
Polyamide is deposited on two banks of the river
during floods so the soil is fertile which is suitable
for agricultural purposes.
At present, the river is getting polluted due to
various reasons. As a result, the river ecosystem is
being destroyed.
So rivers should be protected from pollution, for
their important contribution to human life

10. Characteristics and
Importance of Lakes

11. Characteristics of lake
Lakes are formed naturally. It is like a pond, but
larger in size.
Lake is generally formed by rainwater, river
water, glacier water, and seawater.
Lakes are surrounded by land. The size of the lakes
is much larger.
The water in the lake is either fresh or salty.
The lake is formed at any height from sea level

12. Importance of lakes
Lakes play a very important role in human
life.
It helps in controlling the flows of rivers
and restocking groundwater.
Lakes are commercially important as a
source of fish and minerals and in other
ways

13. Difference between pond and a
lake

14. Properties Pond Lake
Size The pond is smaller. The lake is larger.
Depth The depth of the pond is less. Lake is more deep than pond
Water type Fresh water Fresh or salt.
Wave No wave Have waves
Creation Ponds are natural or artificial. Lakes are natural.
Sunlight
Due to the low depth sunlight can reach the
bottom of the pond.
Due to the more depth the sunlight
cannot reach the bottom.
Shape
Naturally-made ponds are of any size. Man-
made ponds are quadrangular.
Lakes are created by nature.

15. Difference between pond and
river

16. Properties Pond River
Creation The ponds are natural or artificial. The river is natural.
Nature of flow A pond is a kind of stable water body. The water body of the river is flowing.
Depth The depth of the pond is less. The depth of the river is greater.
Slope of flow Ponds cannot flow.
The river flows from top to bottom according
to the land slope.
wave No wave in the pond water. There are waves in the river.
Source of water Rainwater is the only source. Ice meltwater or rainwater
Distributaries and tributaries
There are no Distributaries and
tributaries
A river has many distributaries and many
tributaries.

17. Difference between
river and lake

18. Properties River Lake
Slope of flow
The river flows from top to
bottom
The lake water is stable
Falling place Stream falls into any lake or sea.
A lake’s stream may fall into any river
or sea.
Surrounding structure The boundary is not bounded The lakes are surrounded by land
Water type The water of the river is fresh. The water of the lake is fresh or salt.
River or sea combination
There is a connection between the
sea with the river.
There may be a connection between the
river or sea with the lake.
Distributaries and tributaries
Many distributaries and
tributaries.
No Distributaries and tributaries of lakes.
Nature of flow
The water body of the river is
flowing.
Lake is a kind of stable water body.
Cannot flow or have a slow speed
