A reservoir is like a giant bathtub that holds a lot of water. Just like how you fill the bathtub with water when you want to take a bath, a reservoir collects and keeps water from rivers and rain. This water is saved up so that people can use it later when they need to drink, water plants, or even have fun swimming!
Think of a reservoir as a big treasure chest full of water. Just like how pirates keep their treasure safe in a chest, a reservoir keeps the water safe and ready to use. When there’s not enough rain or when it’s very hot, having this treasure chest of water helps everyone have enough to drink and stay cool.
Imagine a reservoir as a giant sponge that soaks up water. When it rains a lot, the sponge fills up with water, and when it’s dry, the sponge can let the water out to help plants grow and keep rivers flowing. This way, a reservoir helps to share water with everyone, just like sharing toys with friends so everyone can play together.
