· an outlet to let the water flow out of the pond so that you can take out all the fish and clean the pond, the outlet having a screen to keep your fish from getting away when you drain the pond;
· an overflow to let some of the water flow away when there is too much water in the pond. If there is too much water in the pond, some of the water may flow over the banks and some of your fish may get away. The overflow should have a screen to prevent this happening.
