Pond Size And Depth. by Tom Burton. Once the where is decided, we need to determine size and depth. An ideal pond for the average hobbyist is between 23 and 25 feet long by 12 to 13 feet wide and 3 to 4 feet deep.
Koi Pond. While humans enjoy their ponds for swimming, large fish like koi prefer a pond at least 4 feet deep under the waterfall, with shallower shelves for bog and aquatic plants.A deeper pond allows the koi to hide from predators, like cats, raccoons, egrets and cranes.enerally, garden ponds are 18 to 24 inches deep. With the addition of a filter, the waterfall will clean and aerate the pond water, allowing small aquatic creatures, such as turtles, frogs and fish, to thrive amid your water garden plants.
