<human>: How to make a pond in a backyard?
<bot>: To make a pond in your backyard, you will need to dig a hole that is about 4 feet deep and 8 feet wide. Next, line the bottom of the hole with stones or bricks to prevent erosion. Then, fill the hole with water and let it sit for several days before adding plants and fish. You can also add gravel to the bottom to help keep the water clean and healthy. Finally, you can add decorative elements like lily pads, rocks, and aquatic plants to give your pond more character.
