水库 (shuǐ kù): reservoir

After this reservoir was completed, the villages downstream would no longer be flooded during the rainy season.

In order to provide a stable supply of drinking water for the city, the government built a large reservoir in the valley.

This summer was especially dry, and the reservoir's water level dropped to a historic low, making the farmers very anxious.

This reservoir is not only used for flood control, but has also become a great place for nearby residents to fish and take walks on weekends.
