What is the main purpose of a reservoir in the water cycle?

The main purpose of a reservoir in the water cycle is to store fresh or potable water. Reservoirs are typically constructed to capture and hold water for various uses, such as supplying drinking water, irrigation for agriculture, or maintaining water levels for recreation and ecosystems. By storing water, reservoirs play a critical role in managing water resources, especially in regions where water availability can be inconsistent due to seasonal changes or droughts.

Reservoirs also help regulate water flow and supply, which can mitigate the risk of flooding downstream during heavy rainfall and ensure a reliable water supply during drier periods. This storage capability is vital for urban planning, agricultural support, and conservation efforts, making reservoirs an essential component of the broader water cycle.
