reservoir
Definition
A reservoir is a natural or artificial lake or pond that is used to store water. Reservoirs are typically created by damming a river or stream, which creates a body of water that can be used for drinking water, irrigation, hydroelectric power generation, or recreation.
Reservoirs are important for water supply because they can store large amounts of water that can be used during periods of drought or low rainfall. Reservoirs also help to regulate river flow, which can help to prevent flooding and erosion.
The design and construction of reservoirs is a complex process that takes into account factors such as the size of the reservoir, the type of dam, the surrounding land use, and the environmental impact. Reservoirs can have a significant impact on the environment, so it is important to carefully consider the environmental impacts before construction begins.
How can the word be used?

Why are reservoirs important?
AQA Science Exam Question and Answer
Question:
Describe the role of reservoirs in the water cycle and their importance in supplying water to human populations. Provide an example of a reservoir and explain how it contributes to water resource management.
Answer:
Reservoirs play a significant role in the water cycle by acting as storage sites for water, helping to regulate the flow of water through the environment. They accumulate water from various sources, such as rivers, rainfall, and snowmelt, and release it gradually, which aids in maintaining stable water supplies, preventing floods, and ensuring a consistent flow in rivers during dry periods.
A notable example of a reservoir is the Hoover Dam and Lake Mead on the Colorado River in the United States. Lake Mead serves as a massive reservoir that provides water for irrigation, hydroelectric power generation, and domestic use for millions of people in arid regions.
In water resource management, reservoirs offer multiple benefits. They provide a reliable source of fresh water for agriculture, industry, and domestic consumption. Additionally, reservoirs can store excess water during wet seasons and release it during droughts, helping to manage water scarcity and meet demand.
However, reservoirs also have environmental impacts, such as altering river ecosystems and affecting aquatic habitats. Careful management is necessary to balance the benefits of reservoirs with their potential drawbacks. In conclusion, reservoirs are essential components of water resource management, contributing to water availability, flood control, and sustainability for human populations and ecosystems.
