What is a reservoir formed by a dam?
Quick Answer
A reservoir is a stored body of water created when a dam blocks a river. It can be used for drinking water, irrigation, flood control, or hydroelectric power.
The Full Story
When a dam is built across a river, water backs up and floods the valley upstream, forming a reservoir. Some reservoirs are small, while others cover vast areas, such as Lake Nasser behind the Aswan High Dam. Reservoirs can help regulate river flow, but they also change sediment transport, ecosystems, and local communities. Their levels may rise and fall depending on rainfall, water use, and energy demand.
