What is the best size to make a wind pool within 2 meters in front of the house?

Make a wind pool within 2m in front of the house. Generally, the surface area of the fish pond should be 3-4m, with a maximum of 5m. The depth of the pond is limited to 1 meter, the underground part is about 7 cm, and the height of the ground is 3 cm, which can limit the entry of yard debris and accumulated water into the fish pond, causing the pond water to be turbid, which is not good for fish farming.
