Why is it important to have a dam?

Dams are important because they provide water for domestic, industry and irrigation purposes. Dams often also provide hydroelectric power production and river navigation. Dams and their reservoirs provide recreation areas for fishing and boating. They help people by reducing or preventing floods.

Keeping this in view, what are the advantages and disadvantages of dams?

The advantage is linked to the purpose. You can build a dam to provide drinking water, recreation, flood control, power generation or a small dam for livestock. The advantage of each also has some possible disadvantages.

What is the difference between a dam and a reservoir?

A dam is any barrier that holds back water; dams are primarily used to save, manage, and/or prevent the flow of excess water into specific regions. A reservoir is a man-made lake that is primarily used for storing water. They can also be defined as the specific bodies of water formed by the construction of a dam.

Why would a dam be removed?

Dam removal is the process of demolishing a dam, leaving a river to flow freely. All dams negatively affect the aquatic environments of rivers that they are located on, but those effects are often negated by the stated purpose of the dam, whether it is hydroelectric power, flood control, or other functions.
