Key Points
- A reservoir is a human-made water body created by constructing a dam to block the flow of a river or stream.
- Reservoirs are primarily built to store water for purposes such as irrigation, drinking water supply, hydroelectric power generation, and flood control.
- Famous examples include the Bhakra Reservoir (India) and the Hoover Dam Reservoir (USA).
- These artificial water bodies help in managing water resources and ensuring water availability during dry periods.
- Reservoirs also support aquatic ecosystems and recreational activities like fishing and boating.
Additional Information
- Lagoon: A lagoon is a shallow water body separated from a larger water body, such as the sea, by a barrier like a sandbank or coral reef.
- Estuary: An estuary is a coastal area where freshwater from rivers mixes with saltwater from the ocean, creating a unique brackish environment.
- Oxbow Lake: This is a naturally formed water body created when a river meander is cut off from the main flow, forming a crescent-shaped lake.
- Dam Construction: The creation of reservoirs often involves building large dams, such as gravity dams, arch dams, or earthen dams, depending on geological and environmental conditions.
- Environmental Impact: While reservoirs provide significant benefits, they can also disrupt local ecosystems, displace communities, and affect sediment flow in rivers.
