People build dams to control water—to make sure the right amount is at the right place at the right time. River water rises behind dams, forming artificial lakes called reservoirs. The stored water can be used to generate electricity or to supply water for homes and industries, for irrigation or for navigation.
Why Are Dams Built?
Dams are structures built across a river or a stream to hold back water. They are usually built for a variety of reasons, including providing water for drinking and irrigation, controlling floods, and generating power. Dams can be built to store water in times of plenty, so it can be released during times of scarcity. They can also be used to create reservoirs, which provide recreational activities such as fishing and boating.
The most obvious reason why dams are built is to create a reservoir to store water. This water can be used for a variety of purposes, such as providing drinking water and irrigation, controlling floods, and generating power. The stored water can also be used to generate electricity. By using the stored water to drive turbines, electricity can be produced. This electricity can be used to power homes and businesses throughout the region.
Another reason why dams are built is to control floods. By slowing down the flow of water, dams can prevent flooding in areas downstream. The stored water can also be released during times of drought. This helps to mitigate the effects of drought by providing water for drinking and irrigation.
In addition to providing drinking water and controlling floods, dams can also be used for recreation. By creating a large body of water, dams
