how deep does a turtle pond need to be
Garden Pond. A small garden pond with a waterfall should be deep enough that the bog and aquatic plants' soil are under 3 to 6 inches of water. Generally, 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.
