A reservoir is a man-made lake or large storage area created to store water. It is typically used to control and regulate the release of water for irrigation, drinking water, hydropower, and other purposes. Reservoirs are also used to control flooding, provide recreational activities, and generate electricity.
Types of Reservoirs
There are several types of reservoirs that serve different purposes.
Offstream Reservoirs
Offstream reservoirs are created by damming a river or stream to create a larger body of water. This type of reservoir is often used for flood control, irrigation, and drinking water.
Onstream Reservoirs
Onstream reservoirs are created by damming a river or stream in its natural course. This type of reservoir is often used for hydropower and recreational activities.
Storage Reservoirs
Storage reservoirs are created by damming a river or stream to create a large storage area. This type of reservoir is often used to store water for irrigation, drinking water, and other uses.
Benefits of Reservoirs
Reservoirs are beneficial for many reasons.
Flood Control
Reservoirs are used to store excess water during periods of heavy rain, which can help to reduce the risk of flooding downstream.
Irrigation
Reservoirs are used to store water for irrigation, which can help to reduce the need for costly irrigation systems.
Drinking Water
Reservoirs are used to store water for drinking, which can help to reduce the need for costly water treatment systems.
Recreational Activities
Reservoirs are often used for recreational activities such as fishing, swimming, and boating.
Hydropower
Reservoirs are used to generate electricity through hydropower.
Conclusion
Reservoirs are an important part of our water supply system. They provide flood control, irrigation, drinking water, recreational activities, and hydropower. They are essential for keeping our environment healthy and sustainable.
